There are many more parameters, not only alcohol.
e.g. “IBU” and “Stammwürze” (original gravity)
Unfortunately you will not find those on the bottles.
Some micro breweries do.
I came in touch with IPA last year.
I got one brewed with so called aromatic hops.
“double hoped” was it called.
(This special hop came back from USA …GREAT)
Good taste.
Here are the IBU’s for German beer
