Ley Lime Rind from ~1 LB of Key limes removed and placed in Rum for 2 weeks to extract flavor. After 2 weeks, Rind and rum added to secondary using spice ball wih fine filter, and allowed to sit for 5 days in secondary.
Sour mash 5 gallons by heating kettle to ~160 and adding DME, stirring until dissolved. Cooled to 100, added lactic acid until pH<=4.5. pitch L. brevis, Cover with cling wrap or tight kettle lid, wrap in towels.
Daily, open the kettle barely enough to test pH, then reseal & heat until kettle is 110F, remove from heat & rewrap in towels. Repeat daily until pH is 3.7.
Once 3.7 is reached, heat up the kettle, separately mash specialty grains in 2 quarts of water at 151F for 30 minutes before adding to kettle, barely reach a boil, add hops immediately, and low boil for 15 minutes, following additions as they come.
Cool to 70 before pitching WL644 (sour (4.2pH) starter Used but not necessary afaik). Check gravity and allow to ferment at 70-73F.
Gravity should stabilize in 4 days at around 1.010. Heat gelatin (heat 1 packet with 0.5 cup water to 160F with 5sec bursts in a microwave), then sprinkle on top of beer. Place bucket in kegerator and drop internal temp to 40F. 24h at 40F should fine the beer sufficiently for clarity.
Rack to secondary & save at least some yeast (for bottling). Hold open spice ball over beer, and pour Rind+Rum mixture through spice ball. Spice ball will catch rind, and rum will go into beer. Place spice ball in beer for 5 days in secondary.
At bottling, heat up 2 cups water & 6.65oz turbinado sugar. Place in bottling bucket, rack beer to bucket smoothly, then bottle immediately.
Store upright at 70F for three weeks. Label one bottle for <today’s date+7 days>, and label another for <today’s date+14 days>. If week 1 Bottle has no carb, shake all bottles (including week 2 bottle), and label a week 3 bottle. If week 1 bottle is ok but week 2 two bottle does not puff, shake all bottles. Repeat as necessary.
