Sure, but non-obvious things often manifest in culture nonetheless. For example the romans with their mighty aqueducts, cleanliness rules in religion, drinking tea (needs boiled water) or beer/wine (alcohol desinfects), or being obsessed that evil witches dont poison your wells etc.

Also, beer provides large amounts of calories, so it also feeds the consumer with low risk of the "food" getting stale. There's a reason why in Bavaria a fat belly is called a "Bierbauch" ;)

A fat belly is literally called a beer gut or a beer belly in English as well.
