I have an experiment for you, pour e.g. a 0.5L Erdinger Weißen upside down and observe the resulting mess, then do the same with the 0.5% version of the same beer.
There's much less foam in low alcohol beers, so it's not just the alcohol content (unless that affect it directly in some way I don't know about).
- aftoprokrustes 3y agoAs far as I understand a Hefeweizen is put into the bottle with live yeast, which continue the fermentation and create the characteristic thick foam. So indeed, in that case, you cannot have that effect without alcoholic fermentation. But I am more of a Pilsener guy, and there are a few good alcohol free Pils which I am convinced would taste like the "real deal" with the added taste of alcohol.
- OkayPhysicist 3y agoAll beer, historically, was bottled with live yeast. That's how you got the carbonation. Some times we cheat today.
- ouchjars 3y agoAlcohol does change the surface tension so foaming will be different. Ever seen a security guard shake someone's water bottle to check if it's really water? The thing that makes beer foam stay there is the protein content. Yeast contributes some, but it's also in the grain. The foam should be less different if you compared something filtered like Heineken and Heineken 0.0.
