They say that two who live together end up having the same tastes, even in drinks. In a study, published in the behavioural science journal Appetite, researchers from the University of Wrocław in Poland and the University of Dresden in Germany tested the aroma and flavour preferences of 100 heterosexual couples whose relationships ranged from three months to 45 years . They discovered that the longer the couples had been together, the more similar their preferences were.
Organization of the study
The study was based on each participant smelling 38 aroma samples, which included fragrances such as eucalyptus, butanol, orange, smoked meat and caramel. The researchers also dissolved samples of each of the five basic flavours: sweetness (10 grams of D-sucrose), sourness (5 grams of citric acid), saltiness (7.5 grams of NaCl), bitterness (0.05 grams of quinine hydrochloride) and umami (10 g of sodium glutamate). The participants were asked to rate each aroma and flavour sample from 1 (“I like it a lot”) to 5 (“I do not like it at all”).
The more time together, the more similarity in taste
The study examined not only how preferences might be affected by the longevity of a relationship, but also how they might be influenced by how happy the couple was. Happy couples did not have more similar preferences compared to those that were less satisfied. However, greater satisfaction in the relationships had a slightly negative correlation with similar smell preferences.
It is logical that the more years (and bottles of wine) a couple has shared, the preferences end up adapting to each other. The study concluded that even in an unhappy relationship, especially if the couple lives together, it is likely that the couples still smell and eat the same things out of habit, need or convenience.
Couples who drink together are happier
But there is more, because a new study from the University of Michigan states that couples who drink together are happier. Researchers have interviewed 2,700 married couples and analysed how much and how they drink. The conclusions were that the 2 members were more likely to consider themselves happy in their relationship when they shared these habits than those who remained sober while the other consumed alcohol, and vice-versa.
There are still many studies to be conducted to fully understand why the tastes of couples are aligned, but for now, why not use it as another great reason to spend time with our partner and our favourite bottle of wine?
