Want to make your own malt-based colorant to darken up an American-style bock or other beers? This simple method comes from Pete Jones, co-owner (with Michael Stein) of the Lost Lagers historical beer consultancy.
MALT/GRAIN BILL
2 lb (907 g) pale malt
1 lb (454 g) black malt
4 oz (113 g) roasted barley
DIRECTIONS
Mill the grains and, in a mesh sack, steep in 2 gallons (7.6 liters) of 150°F (66°C) water for 30 minutes. Remove the grains, squeezing and rinsing with a bit more water to get only the darker extract. Boil the wort vigorously for about 2 hours, reducing it down to about 2 pints (1 liter)—but be careful not to scorch it! Cover and refrigerate until needed to darken some beer.
