Schwarzbier
Black and far lighter than it looks: a clean lager with a restrained, smooth roast and a dry finish. The beer to hand someone who says they do not like dark beer.

How and when the dark malt goes in. Mashed for an hour, Carafa gives a lager an acrid edge it cannot carry; added at the end, it gives colour and a whisper of cocoa.
Fermentables
| Malt | Weight | Colour | Extract | Of grist |
|---|---|---|---|---|
| Pilsner malt | 2.60 kg | 1.8 L | 37 ppg | 57% |
| Munich malt | 1.40 kg | 10 L | 35 ppg | 30% |
| Caramunich | 0.25 kg | 60 L | 34 ppg | 5% |
| Carafa Special Added at vorlauf, not at mash-in. Steeping it briefly gives colour and cocoa without any of the ash. | 0.35 kg | 400 L | 27 ppg | 8% |
Colour and extract are read from the malt reference, not typed into this recipe, so they are the same figures every other page on the site uses.
Hop schedule
| Hop | Weight | Alpha | Time | Contributes |
|---|---|---|---|---|
| Hallertau Mittelfrueh | 33 g | 4% | 60 min | 15.4 IBU |
| Tettnanger | 18 g | 4.5% | 15 min | 4.7 IBU |
Alpha acid varies by crop year and lot, which is why it lives on the recipe rather than on the variety. Brew to the figure printed on your packet and the bitterness will move; the IBU calculator will tell you by how much.

Strike temperature assumes grain at 20C and priming assumes the beer peaked at 20C after fermentation. Recompute both for your own kitchen on the strike and priming calculators.
Before you package
Take a gravity reading two days apart and only package when it has not moved. A beer bottled while still fermenting keeps fermenting in the bottle, and the sugar you prime with lands on top of whatever was left. At 2.5 volumes this one needs about 128 g of dextrose for the batch.
