Scientists have discovered that a love of coffee can be passed on genetically

As the researchers noted, they used the available data to identify the parts of the human genome associated with whether a person would be inclined to drink coffee. After that, they identified directly the genes and biological processes that might underlie this habit.

The final analysis included data from the UK Biobank, as well as US-based DNA diagnostic company 23andMe. Scientists found a direct link between gene variants and coffee consumption, but many of these genes were also associated with an increased risk of obesity and to substance abuse.
