FAQ
Which ABV formula? +
We use the improved 'Brewer's Friend' formula: ABV = (76.08 × (OG − FG) / (1.775 − OG)) × (FG / 0.794). Accurate above 8% where the simple formula starts to overshoot.
What's attenuation? +
% of sugars the yeast converted. Higher = drier beer. 75% is typical for ale yeasts.
