At the crossroads of flavour science and sustainable brewing, a fascinating discovery has emerged: beer drinkers don’t just vary in taste—they cluster into two distinct camps. A recent study, presented at the American Chemical Society meeting on 18 August 2025 in Washington, DC, reveals that when sampling lagers with comparable bitterness and alcohol levels, beer enthusiasts diverge sharply in their preferences. Some gravitate toward bold, vibrant flavour chemicals—think strawberry-like notes—while others lean into softer, more mellow compounds reminiscent of pineapple.
The Experiment: Tasting, Testing, Splitting
Dr. Devin Peterson and his team at Ohio State University set out to go beyond the realm of trained sensory panels. Instead, they gathered around 135 self-proclaimed beer lovers and invited them to rate 18 lagers over three separate tasting sessions. Despite all beers being matched for bitterness and alcohol, tasters responded in strikingly opposite ways. Mass spectrometry analysis revealed differences in aroma-chemical profiles between the beers. The result?
One faction favored beers high in strong, expressive flavour compounds—brands like Samuel Adams and Brooklyn ranked highly—while the other group flipped the rankings entirely. “Polar opposites in how they’re responding to the product,” Peterson told Nature.
He also noted that these insights unlock new opportunities: brewers can now “tailor these products better for these different cohorts.”
What This Means for Craft Brewers—and for Sustainability

For the independent brewer—driven not just by flavour but by values—the implications go beyond market segmentation. Understanding these two flavor-preference camps means you can direct your innovations with precision rather than experimentation by trial and error.
- Precision reduces waste: Instead of broad-spectrum small-batch trials that may fail to connect with any particular group, brewers can develop two focused lines—one punch-packed, one mellow. This avoids unnecessary ingredients, energy, and wasted product when a new flavor misses its mark.
- Optimize raw-ingredient use: By choosing hops, yeasts, and adjuncts aligned with the desired strong or gentle aroma profiles, brewers can minimize overuse of materials that won’t resonate with their audience.
- Lower carbon footprint: Fewer experimental brews means less energy used in trial runs, fermentation, packaging, and potential disposal. A streamlined, cohort-aware production system is leaner and greener.
- Elevated customer loyalty: Meeting your drinkers where their taste buds are fosters connection. When drinkers feel their preferences are acknowledged and catered to, they’re likelier to return—reducing overproduction of unsold kegs.
In short, this isn’t just flavour science—it’s sustainability in action. By embracing a more discerning approach to flavour and audience, craft brewers can stay inventive while cutting waste, preserving resources, and engaging consumers more meaningfully.

At its core, this study rewrites a long-standing assumption: that beer drinkers form a homogeneous crowd. Far from it—your audience may fall into flavor extremes. As craft brewers, you now have the tools to tailor your offerings, sharpen your sustainability goals, and deepen consumer engagement.
Imagine launching two flagship series: one designed around the energetic, bold strawberry-esque flavours, the other around the serene, pineapple-like calm. Each batch could be scaled according to real demand, reducing overproduction and cooling the carbon footprint of your brew house.
