The recipe for a tripel is simple. You’ll need enough Pilsner malt, and roughly 20% sucrose (table sugar), to reach your target original gravity. The Beer Judge Certification Program (BJCP) gives this range as OG 1.075–1.085. Plus, noble hops — all added near the beginning of the boil — to reach your target level of IBUs. The BJCP gives this as 20–40 IBUs. And finally, an attenuative yeast, with a moderately “spicy” Belgian character, to yield a low final gravity (FG). The BJCP gives this as 1.008–1.014 for a corresponding alcohol content of 7.5–9.5%. And that’s it.
Most Maibock recipes are very simple. The beer should be pale and better attenuated than other bockbiers, so the grist is usually 100% base malts. Crystal malts are not needed because caramel flavor and the extra body that crystal malts add are not desired. In the same vein, there is no call to add CaraPils (or CaraAnything) to your grist. A simple mix of Pilsner, Vienna, and Munich malt is ideal.
