Instructions
Mash
Need to lauter at higher temp than usual to compensate for adjuncts. Pull a decoction to mash-out, aiming for 170-175F.
Boil
No bittering hops added during boil.
Add lactose during last 10 minutes of boil.
Primary fermentation (7 gal plastic bucket)
Pitch yeast and ferment at room temperature, ideally 68-70F. Once active fermentation begins dying down, add first round of dry hops, 1oz each added to sanitized cloth bags. Leave until active fermentation dies down almost completely (about 1 bubble per 15-20 sec in airlock), then rack to secondary.
Secondary fermentation (3 gal glass carboy)
Beforehand, prepare 3 lb frozen mango chunks.
Allow to thaw enough to soften.
Smash in a sanitized container with a sanitized tool/hands.
Seal sanitized container and refreeze.
Before racking, allow to thaw to avoid shocking yeast.
Add mashed mango to sanitized carboy. Add second round of dry hops, 1oz each added to sanitized cloth bags. Rack beer onto mango and dry hops, reseal and allow to complete fermentation at room temperature, ideally 68-70F. Take gravity readings before & after racking, and note increase by mango. Allow to rest at least 10 days before bottling.
Bottling
Before bottling, draw a tiny sample of beer and measure pH. Assuming pH is above 4.8, dissolve small amounts of citric acid, remeasure, and taste, aiming for 4.0 to 4.8. Once satisfied, scale up amount needed per 12 oz bottle. Add to each bottle:
4 dextrose carb tabs (not the usual 5).
One pinch of CBC-1 bottling yeast.
Measured amount of citric acid.
Bottle directly from secondary, using two-holed carboy seal and air filter to reduce contamination.
