In cafés from Stockholm to Singapore, something curious is happening to the humble latte. The milk has changed – but the meaning of what’s being poured has changed even more. Oat milk, once a fringe choice in vegan corners of Brooklyn and East London, now commands entire refrigerator shelves in mainstream supermarkets. In London alone, sales of oat milk have more than doubled in recent years, outpacing almond and soy. But its rise has sparked a question with global implications: is this just a Western infatuation – or the beginning of a broader, localized reinvention?

As plant-based milks grow in popularity, they are revealing more than just a shift in taste. They have become markers of identity, class, health politics, and cultural resistance. For younger generations in Western cities, oat milk is as much a badge of sustainability as it is a coffee additive. But in Asia, where soy and coconut milk have been kitchen staples for generations, Western brands often appear as tone-deaf outsiders. In India, almond milk is aspirational, signifying affluence and global awareness. In Japan, flavored soy milk is sold in vending machines next to corn soup and iced matcha. Each tells a story – not just of diet, but of what progress tastes like in different corners of the world.

The Western Story: When Climate Guilt Meets Café Culture

In the West, plant-based milk has surged from niche to mainstream at breakneck speed. In the UK, oat milk has overtaken almond as the best-selling non-dairy option, with the market valued at over £146 million in 2023 and projected to reach more than £430 million by 2030—a growth trajectory that reflects not just a change in taste, but in values. In the United States, the plant-based milk market has experienced significant growth, with revenue increasing from $2.71 billion in 2024, more than doubling since 2019. This surge reflects a broader trend, as supermarkets now allocate entire aisles to milk alternatives, accommodating the rising consumer demand.​

For Gen Z and Millennials, this shift is as much about values as it is about flavor. The rise of “climatarian” diets—eating based on environmental footprint—has positioned oat milk as the virtuous option. It requires far less water than almond milk (48 litres per litre vs. 1,600) and carries a lower carbon footprint than cow’s milk. Among baristas, oat milk’s texture and foam-ability have cemented its status as the café go-to.

But these motivations are not universal. Among Gen X and Boomers, plant-based milk adoption often stems from health concerns—lactose intolerance, cholesterol, weight management—rather than climate ethics. Many still view oat and almond milk as a wellness product, not a moral choice. And the taste? It’s tolerated more than it is loved.

Despite its early momentum, the plant-based milk category in the U.S. is starting to show signs of fatigue. In 2024, sales declined by 5.2%, driven more by inflation-driven price sensitivity than by waning interest. What we’re seeing at Kadence International is that consumers are making sharper trade-offs at the shelf. While oat milk is still seen as on-trend, its pricing—often double that of dairy—has started to generate real resistance.

Minor Figures, a UK-based oat milk brand, has carved out a niche among creative professionals. Its hand-drawn packaging, minimalist design, and carbon-neutral commitment resonate with urban Gen Z. The brand installed oat milk refill stations in eco-minded cafés in East London, turning sustainability into something tangible. Co-founder Stuart Forsyth emphasizes their approach: “We want to grow sustainably, we want to grow ethically and just see where this sort of journey takes us.”

Still, even Minor Figures must contend with growing skepticism about “performative sustainability.” A growing share of younger consumers now want traceability—where was it grown? What happens to the packaging? As oat milk begins to look like the new default, the question becomes: what comes after default?

Research-brief

Southeast Asia: Taste First, Sustainability Later

If oat milk is the sustainability symbol of the West, in much of Southeast Asia, it’s still a curiosity—often priced high, unfamiliar in flavor, and positioned more as a lifestyle accessory than a kitchen staple. Here, taste and tradition are still the gatekeepers, and consumer priorities follow a different rhythm.

Soy and coconut milks remain the dominant non-dairy choices across the region. Long before Western plant-based trends took hold, these ingredients were already foundational in Southeast Asian cuisine. From Indonesia’s tempeh to Thailand’s tom kha, from soy puddings in Vietnam to rich coconut-based curries in Malaysia, non-dairy milk isn’t an “alternative”—it’s the original.

Yet, the surge of interest in plant-based eating is not being ignored. The market for dairy alternatives in Southeast Asia hit USD 3 billion in 2024 and is forecast to reach USD 4.1 billion by 2030. But the motivations driving that growth are not always what Western marketers expect.

For urban Gen Z consumers, the shift is being fueled by café culture and aesthetic appeal. In Singapore, Bangkok, and Ho Chi Minh City, oat milk is showing up in third-wave coffee shops, where latte art meets lifestyle branding. The creamy mouthfeel and mild taste of oat milk plays well with espresso, and baristas often frame it as the more “sophisticated” or “global” option. But the price—often two or three times higher than soy or coconut milk—makes it more of a treat than a household switch.

Health and digestion are also central to plant-based appeal. For Millennials balancing fast-paced urban lives with rising wellness awareness, soy milk retains a stronghold due to its protein content and familiarity. It’s not uncommon to see fortified soy drinks marketed for beauty benefits, gut health, or as part of fitness routines.

Among Gen X and Boomers, however, there’s little appetite for novelty. Traditional dairy is still prized, especially in countries like Vietnam, where sweetened condensed milk remains the heart of the national coffee. Coconut milk is not just nostalgic—it’s seen as natural, trusted, and tied to home cooking.

For Western brands attempting to gain traction here, the learning curve is steep. Oatly’s entrance into the region began with Malaysia and Singapore, distributed via speciality grocers and upscale cafés. The company announced in 2022 that Southeast Asia would form a “growth corridor” as part of its Asia expansion. But by 2024, it had shuttered its Singapore production facility to consolidate manufacturing back to Europe—a sign that demand in the region had not yet scaled fast enough to justify local production.

Oatly continues to maintain shelf presence in Singapore, but its growth in the region faces challenges. In December 2024, the company announced the closure of its production facility in Singapore as part of an asset-light supply chain strategy aimed at improving cost structures and reducing capital expenditures. This move reflects broader operational adjustments in response to evolving market dynamics in Asia.

The plant-based milk market in Singapore is becoming increasingly competitive, with local brands like Oatside gaining traction. In June 2023, Flash Coffee announced it would serve Oatside as the default in all milk-based beverages across its 24 outlets in Singapore. This highlights the growing consumer interest in plant-based options and the competitive landscape Oatly faces.​

It’s evident that for plant-based products to succeed in Singapore, they must appeal to consumers in both taste and affordability. The sustainability pitch alone often isn’t sufficient; products need to meet consumer expectations in flavor and be competitively priced to gain widespread acceptance.

Local innovation may hold the key. In Thailand, companies are experimenting with rice milk made from surplus grains. In Indonesia, startups are blending coconut and cashew milk to cater to local palates while improving texture. Unlike oat, which has to be imported and processed, these ingredients are homegrown—offering not just flavor familiarity but economic resonance.

The tension in Southeast Asia isn’t whether consumers will adopt plant-based milk—it’s which ones, and why. Taste leads. Price follows. Sustainability, for now, lags behind. But for a younger class raised on Instagram, global branding, and iced matcha oat lattes, the next shift may arrive faster than expected.

Japan: Tradition Meets Innovation

In Japan, plant-based milk isn’t a trend—it’s tradition. Long before Western oat and almond milks arrived on convenience store shelves, soy was already woven into daily life. From tofu to miso to soy-based desserts, the legume’s liquid form has been consumed for centuries—not as a replacement, but as a cultural staple.

This historical baseline gives Japan a unique position in the global plant-based milk story. While much of the West is shifting away from cow’s milk, in Japan, dairy was never dominant to begin with. Lactose intolerance affects approximately 45% of the population to some degree, and the country’s culinary heritage has long favoured plant-based ingredients.

Yet even here, the landscape is shifting—quietly, and with the precision Japan is known for. In 2024, the soy milk segment still made up the overwhelming majority of plant-based milk sales, but oat and almond are inching upward. Projections estimate Japan’s oat milk market will expand from approximately $51.7 million in 2024 to over $163 million by 2033, reflecting a compound annual growth rate of 12.6%.

But growth in Japan doesn’t mirror that of its Western counterparts. Oat milk here is not a lifestyle statement. It’s more likely to be encountered in a café serving Nordic-style pastries than in a supermarket fridge. In Tokyo’s upscale coffee districts—Daikanyama, Aoyama, and parts of Shibuya—young professionals are experimenting with oat lattes, but the movement is still niche.

Soy milk is still the default. People are curious about oat milk, but it’s expensive and unfamiliar. Soy is part of the Japanese identity.

The soy milk aisle in Japan looks nothing like its Western equivalents. There are over 30 flavors of soy milk in most convenience stores—banana, sweet potato, black sesame, and even matcha. Sold in small, colorful cartons, these drinks are as much a snack as a supplement. They appeal across generations and demographics, from school children to business executives.

Almond milk, introduced in earnest in the early 2010s, is viewed as a beauty product as much as a drink—touted for its vitamin E content and its role in “clean eating” routines. It’s marketed in lifestyle magazines and television ads featuring pop stars and Olympic athletes.

So where does that leave oat? Still finding its place. Japanese consumers value texture and subtlety in flavor—qualities that oat milk sometimes struggles to deliver in traditional dishes or teas. But its creamy body is finding fans in the coffee world, and as more cafés experiment with it, familiarity may breed demand.

What’s clear is that plant-based milk in Japan isn’t driven by environmental activism or dietary rebellion. It’s driven by harmony—with the body, with the palate, with the past. While the West frames oat milk as progress, in Japan, progress tastes familiar—it just might be flavored with yuzu or kinako.

India: Plant-Based Milk as Urban Status and Spiritual Alignment

In India, dairy isn’t just nutrition—it’s ritual. From temple offerings of milk to the everyday comfort of chai with malai, dairy products are woven into the country’s emotional and religious fabric. The white splash in a steel tumbler holds centuries of symbolic weight. So any conversation about plant-based milk here starts not with a health trend, but with the question: what could possibly replace something sacred?

The answer, for now, is: not much—but something is beginning to stir.

India’s plant-based milk market is still young, valued at around USD 50 million in 2024, but it is projected to grow at nearly 15% CAGR over the next six years. That growth, however, is uneven and tells a story less about dietary shifts and more about social signalling.

For Gen Z in India’s metros, plant-based milk is about cruelty-free living, fitness influencers, and Instagrammed morning routines. It’s not uncommon to see “dairy-free” smoothies and almond milk lattes showcased in the digital lives of young professionals in Bengaluru, Delhi, or Mumbai. These consumers often cite animal welfare, clean eating, and compatibility with lactose intolerance—affecting an estimated 60% of the population—as reasons for switching. But the shift is as much aesthetic as it is ethical. Almond milk isn’t just good for you; it looks good in a glass.

Millennials, especially those navigating careers abroad or within cosmopolitan India, are caught between reverence for traditional staples like paneer and ghee, and a rising curiosity about global wellness norms. Many are not rejecting dairy outright, but are experimenting with substitutes during certain meals, fasts, or fitness cycles. The language of Ayurveda also looms large—“easy on digestion,” “balance for pitta”—guiding product marketing and consumer trust.

For Gen X and Boomers, though, the idea of dairy-free milk is still foreign. Cow’s milk is considered pure in Hindu tradition. To deviate from it can feel like cultural heresy, particularly in religious households. Even within vegan circles, spiritual negotiations are common—almond milk in the smoothie, but cow’s milk in the temple.

And yet, there is movement at the margins.

Image credit: Good Mylk Co.

One company pioneering this shift is Goodmylk, a Bengaluru-based startup founded by Abhay Rangan in his teens. The company produces cashew and oat-based milk, peanut curd, and vegan butter. What sets it apart is its insistence on affordability and accessibility. “If we make it premium, we limit who gets to choose it,” Rangan said in an interview. Goodmylk raised $400,000 in seed funding and has focused on scaling without pricing itself out of the Indian middle class.

The brand also localizes its innovation. Mung bean and millet-based milks are in development—grains familiar to Indian households, now reimagined for lattes and cereal bowls. This strategy isn’t just functional—it’s cultural. “People trust what they’ve grown up with,” Rangan notes. “If we can use those same ingredients in new ways, we don’t have to change people. We just meet them where they are.”

What India reveals, perhaps more than any other market, is that the future of plant-based milk may not be about substitution—but about addition. The almond milk doesn’t replace the dairy in the chai. It sits next to it in the fridge, as an option, a symbol, a signal of modernity. Milk, in this context, is not just nourishment. It’s narrative.

Cross-Cultural Observations: What Tastes Like Progress?

From Bangkok cafés to Berlin grocery aisles, plant-based milk carries different meanings depending on where you are—and who you ask. To understand the global arc of milk alternatives, it’s not enough to look at adoption rates. You have to ask what each product represents in a cultural context. Because in the world of milk, progress has many flavors.

In the UK, oat milk has become shorthand for ethical living. It’s the fuel of the “climatarian”—those who select food based on its carbon footprint. It helps that oats grow abundantly in Europe and require far less water than almonds. But this is also about optics. Oat milk in a flat white signals something specific: sustainability without sacrifice. It says, “I’m paying attention.”

In Japan, soy milk is the opposite of a trend—it’s a staple. You’ll find banana soy milk in vending machines, black sesame soy in school lunch trays, and unflavored soy behind the counter of every ramen bar. Oat milk, by contrast, is a foreigner: imported, expensive, and still largely a café novelty. Where Western markets romanticize innovation, Japan reveres the familiar.

In India, almond milk is climbing—but it’s doing so as a marker of status. Its presence in a smoothie bowl or a vegan café menu connotes wellness, modernity, and a kind of cosmopolitan sophistication. It’s aspirational, not essential. Meanwhile, mung bean and millet milks are emerging quietly from startups like Goodmylk, using ingredients that feel both futuristic and deeply local.

In Southeast Asia, coconut milk is tradition in liquid form. It’s thick, aromatic, and the base of comfort food across generations. Oat milk, by comparison, is still figuring out how to earn trust—or at least a spot in the fridge. Soy milk, sold sweet and chilled at street stalls and in grocery chains, continues to dominate the category for its price, protein, and familiarity.

And then there’s the matter of price. Across nearly every market, oat milk carries a premium—often double or triple the price of cow’s milk, and far more than local alternatives. In the UK, it retails for £1.90 per litre compared to £1.20 for dairy. In Southeast Asia, import costs push oat milk into the realm of aspirational indulgence.

This price disparity cuts to the heart of a growing identity tension: who gets to eat for the planet? In many regions, sustainability remains a luxury. And with that, a subtle backlash is brewing against the Westernisation of food. Consumers in Asia, Latin America, and Africa are increasingly questioning why “plant-based” must mean foreign, expensive, and out of touch with local ecosystems. As these questions simmer, the most forward-thinking brands aren’t scaling Western models—they’re turning inward. Instead of exporting oat milk to Jakarta or Mumbai, they’re asking: what’s already growing here? And how do we make that the new norm?

Concept and pack testing is an area that’s ripe for innovation – a need made ever more pressing during the Covid-19 pandemic. Watch this 15 minute video to hear how we worked with Asahi UK to pilot the use of augmented reality for this purpose, testing pack designs for Fuller’s London Pride.

We’ll share our key findings, focusing specifically on what we discovered about the value of using AR versus static 2D images. These insights will have value to any researcher looking to broaden their toolkit and harness new technologies in the “new normal”.

This is is the first of Kadence International’s Micro Masterclasses, 15 minute videos designed to provide fresh thinking and a new perspective on research methodologies.

Before they reach the target market, products or services always start off as unproven ideas. But in order to avoid costly failures, businesses need to understand whether or not they’ll be a hit with consumers.

Concept testing is the process of using qualitative or quantitative research in order to test your ideas ahead of launch. It enables you to ascertain which features are likely to be popular with the target audience and which may need changing. 

Key methodologies and testing methods can include in-depth interviews, online communities and the use of a testing survey to gather feedback on your potential product.

Paving the way to success

Testing product ideas with your target audience enables you to optimize your approach before introducing products to the market, helping you to get features right from the earliest stage and dramatically boosting your chances of success by asking potential customers what they think. It can also prevent costly failures, so an investment in effective concept testing is worthwhile.

After all, seemingly minor product features can have a fundamental effect. In this way, market research enables you to find out what potential customers care about in order to determine which attributes should be incorporated into the final design ahead of the official product launch.

Product and concept development

Behind almost every successful product is a careful research and development phase – and we’ve worked with some of the biggest brands to take their big ideas and turn them into products consumers love through concept and product testing.

But how do you test a product concept effectively?

Here are five examples of how to test product concepts for any potential product.

1. Run an online survey to test overall concept appeal and to narrow down your options

A concept test survey can be a powerful tool. A testing survey can reach large audiences of carefully targeted consumers, providing rich data to be analyzed. It is possible to test a number of concepts in order to understand their appeal and to help you decide which concepts to take forward for further testing.

Product developers know that the use of effective survey questions is a proven way of generating relevant information on which to base future decisions. Questionnaires are typically used for obtaining valuable data. For example, to ascertain how many potential customers there are, whether they would find such a product or service useful, and the sort of price they would be willing to pay. 

The key is to ask the right people the right questions, and to ask enough people to get meaningful results. Often a Likert scale is used, a type of scale used to rate various features or attributes in the eyes of end users. Do bear in mind, too, that you need to approach a significant sample of people who match the profile of your target audience when sending out questionnaires.

Effective concept testing can also give you relevant information and clear pointers as to which demographic groups, geographies or market segments will get as excited about your idea as you are.

2. Employ conjoint analysis to understand which features really matter to consumers

As well as asking potential customers which concept they prefer, you can use techniques like conjoint analysis to gauge which product features are most important. This is a technique which involves presenting people with a series of attributes and asking them to rank them in order of appeal.

Conjoint analysis is regarded as an effective way of gaining detailed insights. Essentially, it’s a way of measuring the value that customers place on a product’s specific features. It typically works via a survey, in which participants are shown a combination of attributes and asked to compare or rank them. It can help measure and understand customer preferences for particular features to generate actionable insights to guide product development.

Whilst the process involves offering respondents a range of choices. It’s important, however, not to overload respondents so that they remain fully engaged with the process.


This approach can help you identify the features that matter to consumers. Use this to categorize features into ‘need-to-have’ versus ‘nice-to-have’. Consider which features and functionality your product really needs in order to be compelling to the target market to prioritize your investment.

3. Use qualitative methodologies to hone your ideas along with the target audience

Group discussions are a tried and tested way of getting rich qualitative input. We can bring groups of potential customers together – face-to-face in a focus group or in an online community – and conduct a carefully guided discussion, often with prototypes or other stimuli to spark conversation. This allows us to drill down into the product features that consumers really want or need. Qualitative research can also reveal unmet needs, inspiring further development and ensuring your product or service has the edge over the competition.  

 
In some cases, qualitative feedback can be gained by conducting one-on-one in-depth interviews. This is particularly useful if you have a detailed or complicated concept that’s targeted at a niche B2B audience.

It’s important to use open-ended questions to gather insights: Ask respondents what they like and dislike and give them the space to explain their views. This provides the opportunity to get objective feedback from your target audience without restrictions or bias and to obtain detailed and actionable feedback. 


Questions can include, for instance, ‘How appealing are following the features?’ or ‘Which of the following attributes are most important to you?’ or ‘How well do these statements describe the product?’ 


Choosing the right questions, moderating the discussion, probing at the right intervals and keeping respondents engaged is key to successful product concept testing. With so many products failing, testing your concept early is also vital. By testing product concepts thoroughly and early, you’ll know which concepts are likely to drive revenue before you have invested too much time and effort in development.

4. Embrace an agile and iterative testing approach

Another way to test product concepts is to develop an agile and iterative testing approach. Online methodologies like online communities lend themselves well to this, as it’s possible to test concepts, gain feedback, adapt the concepts based upon this and then retest them with consumers.

An online community is an online research platform where consumers are brought together to take part in a series of tasks. The discussion is curated by our team of researchers in order to gain in-depth feedback, which will enable effective concept iteration.

The online community platforms we use have built-in features for concept testing. For example, it’s possible to mark up images to highlight which aspects you like or dislike, adding detailed commentary. The results of this exercise can be analyzed, and the concept iterated accordingly, with the new and improved idea put back into the community for further feedback and testing. The result? By harnessing feedback loops to refine and retest, you’re able to develop the strongest concept possible. 

Even after your product has launched, there’s real value in continuing to gain feedback. Once your product is in consumers’ hands, there’s more to learn about the role it plays in people’s lives and any unforeseen pain points that could require further changes to address. Be ready to test your product concept to ensure it gets better and better. By honing and refining your product features, you can stay ahead of the competition. So always refine and iterate. Successful product innovation is never finished. The beauty of product concept testing is that you have the luxury of being able to respond to feedback until you hit on the optimum prototype. 

5. Harness new technology to bring ideas to life for consumers 

To get the most out of respondents during a piece of concept testing research, it’s important that you bring concepts to life by creating stimuli that enable the target market to picture your proposed products or services. With our own design team in-house we can take your initial ideas and turn them into beautiful mock-ups that ensure the core idea is clear.

To take this a step further, we are currently exploring how to use augmented reality (AR) to bring concepts to life, thereby eliciting higher-quality insights. Through AR, we can create 3D digital prototypes that consumers can place in real environments using their phones. Not only do immersive methods like this deliver richer insights, but they also allow you to test ideas in context.

Get under the skin of your potential customers in this way and let their feelings and needs guide you towards the solutions with the most potential. The results will speak for themselves.
