Calc OG: 1.052 BE: 70% DP: 118 SRM: 10 IBUs: 60 TGW: 2.0 lbs.
Yeast: Safale US-05
Water Adjustment:
• Tap Water Profile (ppm): Ca=4 Mg=2 Na=69 Cl=11 SO4=15 CaCO3=128 HCO3=153
• Target Water Profile (ppm): Ca=87 Mg=10 Na=46 Cl=97 SO4=94
• Steps to Achieve Target Water Profile:
- Add 55mg (1/11 of 0.6g Campden tablet) of potassium metabisulfite to 2.0 gal tap water (remove chlorine)
- Add 1 gal distilled water for total 3.0 gal (33% dilution to lower Na level to 46)
- Add 1.0g CaSO4, 2.1g CaCl2, 1.0g MgSO4, 0.3g Ca(OH)2
- Acid Addition: None
• Target Mash pH = 5.5, Actual Mash pH = 5.4, Post-Fermentation pH = 4.1
Procedure:
Bring 2.5 qt (2qt 16oz) brewing liquor to 165F (water : grist ratio = 1.25 qt : 1 lb). Mash grains for 60 min at 152F. Bring 1.5 gal sparge water to 170F. Sparge grain, accumulating 1.75 gal in boil kettle. Bring to boil. Add 3g Mosaic, boil for 50 min. Add flocculant, boil for 5 min. Add 4g Mosaic, boil for 5 min. Turn off heat. Chill pot to 62F. Rack wort to secondary pot with 2 drops Fermcap-S. Rack wort to carboy. Aerate.
Hydrometer reading (Original Gravity) = 1.054
Pitch yeast. Fit air-lock.
Fermentation:
Fermenter is at 64F and started bubbling within a few hours--still strong at 24 hrs. Bubbling has slowed after 36 hrs. After 72 hours raise the carboy temp 1-2 degrees every 24 hours until carboy is 72F, then remove from the fermentation chamber and raise to 72F. Allow fermentation to continue for 3 more weeks. Dry hop with 4g Mosaic for the last 72 hours.
Bottling:
After 4 weeks fermentation, rack to bottling pot.
Hydrometer reading (Final Gravity) = 1.009 ABV = (1.054 - 1.009) x 131.25 = 5.9%
Add priming sugar: 23g Sucrose. Filled 9 - 12oz bottles. Allow 2 weeks, then refrigerate.
Notes:
Nice hoppy flavor
