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:
- 8.8 kg (19.4 lb) of base malt to reach OG 1.100. Specialty malt displaces some of that and usually contributes fewer points.
- 62 g (2.2 oz) of a 10% alpha pellet hop at 60 minutes for 53 IBU. Late and whirlpool additions add aroma without moving this much.
- A yeast attenuating around 76% to finish near FG 1.024. 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 balanced, leaning malty — a BU:GU ratio of 0.52, meaning 53 IBU against 100 gravity points. The gravity range implies about 76% apparent attenuation, which is what you should be selecting a yeast for.
A beer in the middle of this style lands around 10.0% 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.
