Calc OG: 1.054 BE: 75% DP: 91 SRM: 29 IBUs: 27 TGW: 2.0 lbs.
Yeast: Nottingham
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=129 Mg=10 Na=41 Cl=83 SO4=81
• 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 (40% dilution to lower Na level to 41)
- Add 0.6g CaSO4, 1.5g CaCl2, 0.9g MgSO4, 1.2g Ca(OH)2
- Acid Addition: None
• Target Mash pH = 5.5, Actual Mash pH = 5.3, Post-Fermentation pH = 4.2
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 5g Northern Brewer, boil for 30 min. Add 6g Fuggle, boil for 20 min. Add flocculant, boil for 10 min. Turn off heat. Chill pot to 58F. Rack wort to secondary pot with 2 drops Fermcap-S. Rack wort to carboy. Aerate.
Hydrometer reading (Original Gravity) = 1.052
Pitch yeast. Fit air-lock.
Fermentation:
Fermenter is at 60F 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 2-3 degrees every 24 hours until carboy is 72F, then remove from the fermentation chamber. Allow fermentation to continue 3 more weeks.
Bottling:
After 4 weeks fermentation, rack to bottling pot.
Hydrometer reading (Final Gravity) = 1.009 ABV = (1.052 - 1.009) x 131.25 = 5.6%
Add priming sugar: 23g Sucrose. Filled 9 - 12oz bottles. Allow 2 weeks, then refrigerate.
Notes:
Nice head and color, and great flavor.
