Notes

Matt Mead's 'Treefort' Tropical Stout recipe, Gold Medal winner @ NHC 2024, scaled from 5.5 to 3.0 gallons.
His notes: Everything is standard brewing procedure (If you miss your starting gravity just add a little pale DME to get it to 1.070 or 1.075). I just fermented in my basement around 60–70°F (16–21°C). 68°F (20°C) was my target. Once fermentation was completed, I transferred to a keg and carbonated to 2.4 vol. of CO2. No need to use Brewtan B or any anti-oxidation products on this beer, as aging improves it over time. I entered this in competitions over the months and scores kept improving as it aged and got a little more caramel and rum-raisin character. No oaking either, although you can if you want. It might add some vanilla notes and tannins, which wouldn’t be a bad thing, but might take away from it being considered a tropical stout. Either way, it’s an amazing base stout.
