5/10 confidence.
When a very large food survey was reduced to factors - clusters of things people tend to like together - one of them grouped coffee, beer, red wine and other bitter adult drinks. They share a quality: nobody likes them at first, and liking is acquired. This position came out attached to that cluster. It sits near TSNARE1, a gene involved in moving vesicles inside neurons, which is a long way from taste and is a reason to hold the finding lightly. The survey it comes from did test its own results in separate cohorts, and only a minority of them held up.
Good to know: Coffee, beer and wine cluster together because they are all acquired bitter tastes. The gene here has no obvious connection to taste, which is a reason for caution. This is about liking the group of drinks, not about how much of them anyone drinks.
Fun fact: Bitterness is the taste humans are born most averse to, which is thought to be a defense against poisonous plants - making the popularity of coffee and beer a genuinely odd fact about our species.
Discovery: Food-liking factors were mapped genome-wide in UK Biobank in 2022.
