A starting point for a 19 liter batch

Aiming at the middle of the range, at 72% brewhouse efficiency, using base malt at 36 PPG:

  • 93018.1 kg (205069.6 lb) of base malt to reach OG 1060.000. Specialty malt displaces some of that and usually contributes fewer points.
  • Infinity g (Infinity oz) of a 10% alpha pellet hop at 60 minutes for 48 IBU. Late and whirlpool additions add aroma without moving this much.
  • A yeast attenuating around 5% to finish near FG 1011.500. Mash temperature will move this by several percent in either direction.

These are arithmetic, not a recipe — they tell you the size of the grain bill and hop charge you are aiming for, so you can tell straight away whether a recipe you are looking at is in the right territory.

Reading the numbers

At the midpoint of the ranges this style is clearly malt-forward — a BU:GU ratio of 0.00, meaning 48 IBU against 1059000 gravity points. The gravity range implies about 5% apparent attenuation, which is what you should be selecting a yeast for.

A beer in the middle of this style lands around 5.8% ABV. The ABV calculator will tell you where yours actually finished once you have both gravity readings.

Judges assess against the full written style description — aroma, flavor, mouthfeel and history — not only these figures. The BJCP guidelines carry the complete entry. What the numbers give you is the target to design a recipe against.
