Yeast: Safale US-05

Procedure:

Bring 1.5 gal water to 152 F. Mash grains for 60 min. Bring .5 gal sparge water to 160 F. Sparge grain bag for 15 min. Add sparge wort to boil kettle. Bring to boil. Add 3.5g Chinook, boil for 30 min. Add 3.5g Chinook and 3.5g Cascade, boil for 20 min. Add 3.5g Chinook and 3.5g Cascade and flocculant, boil for 10 min. Add 3.5g Chinook, 7g Cascade, 7g Amarillo, and 7g Simcoe. Turn off heat. Chill pot to 72 degrees. Rack wort to secondary pot with 2 drops Fermcap-S. Rack wort to carboy. Aerate.

Hydrometer reading (Original Gravity) = 1.063

Top off volume to one gallon. Pitch yeast. Fit air-lock.

Fermentation:

Fermenter is at 72 F and started bubbling within a few hours--still very strong at 24 hrs. Bubbling has slowed dramatically after 36 hrs. Allow 2 weeks.

Bottling:

After 2 weeks fermentation, rack to bottling pot.

Hydrometer reading (Final Gravity) = 1.009                                                                 ABV = (1.063 - 1.009) x 131.25 = 7.0%

Add priming sugar. Filled 9 - 12oz bottles. Allow 2 weeks, then refrigerate.

Notes:

After initial shock of sharpness (combination of hops and grapefruit), this IPA is refreshing, with dry finish.
