Frequently Asked Questions

▾

What's the difference between ABV and IBU?

ABV: alcohol content (strength); IBU: bitterness units (not strength related).

Do different beer styles have different ABV?

Yes; lagers 4-6%, IPAs 6-8%, stouts 5-8%, imperial styles 8-12%+.

Common Mistakes to Avoid

▾

!Assuming darker beer equals higher ABV (not true)
!Not accounting for gravity adjustment formulas at high ABV

⭐

Did you know?

Craft breweries produce higher ABV beers (6-12%); macro breweries lower (4-5%) for volume drinking.
