Most of the beers I like are 7.5%, except stouts which are 10-12%. They also come in large 16oz cans. Two of these is almost 4 drinks. "Craft beer enthusiast" can start to approach heavy drinker very quickly.
I often socialize with a Belgian guy, and he will choose similarly strong Belgian beers, but will almost always split the bottle with someone else. I think that can would probably be split three ways — it is equivalent to 2½ to 3 reasonable glasses of wine.
Sometimes that means drinking less, but it might also mean each person tries a wider selection of beers.
(A deleted comment asked for a "European" view, and I should make clear this is not a unified European view. That's impossible, as drinking culture varies massively between countries, by drink, culture, law and tax.)
Here was the reference I used. Small glass of red/white/rosé wine (125ml, ABV 12%) 1.5 units Bottle of lager/beer/cider (330ml, ABV 5%) 1.7 units
473ml*0.12 = 57ml of alcohol (!) - so almost 6 10ml units in a single can??? so two of those 12% stouts would be 11.4 units! Ouch... Yeah. Maybe switch to one of them as a special treat once in a while. :)
But the comparisons in this discussion are all confused, as the first person wrote "US measuring cup" but used UK alcohol "units" (which are 10mL = 6g), but the US "standard drink" contains 11g = 18mL alcohol.
UK units are nicer to calculate, as an example 150mL glass of 13% wine contains 150 × 13 ÷ 1000 → 1.95 "units" alcohol (19.5mL).
But the US standard drink is probably nearer to what people actually consider one drink. The UK site shows that typical drinks are nearer 2-3 units [3].

"For example, in the United States, a standard drink contains about 14 grams of alcohol." "Different countries define standard drinks differently. For example, in Australia, a standard drink contains 10 grams of alcohol,[4] but in Japan, one "unit" contains approximately 20 grams."
I guess if you're paying by the bottle who cares. Ensures more consumption?
And, was more noting how people could deceive themselves. I just fetched one of the large wine glasses from the kitchen. Filled but well below the rim (maybe a couple of cm below) it was 2 cups of water (so 6 units!) - I emptied out the water and filled it with 1 cup of water (so well over the 2 units) the glass was less than half full. Visually looked about a third of the way up the glass due to the curve.
A bottle of 5% beer is defined as 1.7 units, therefore a bottle of 6.5% or 7% craft beer would be well over 2 units.
