Prior to Brew Day

Collect water to allow chlorine to dissipate.

Brew Day

Heat 8 gallons of water to 155°.  (Unfiltered Dover City water with chlorine removed.)

Gently dough in grains until all grain is covered by water. Add 1/2 tsp gypsum and 1/4 tsp epsom salts and stabilize pH at 5.2

Mash grains at 150° for 1 hour.

Remove “grain bag“, rinse, squeeze and allow grains to drain.

Bring wort to a boil.

Once wort is boiling, add 1 oz Centennial hops and continue for 45 minutes.

Add 1 oz Centennial hops and continue boil for another 10 minutes.

Add whirlfloc, yeast nutrient, 1 oz Centennial hops and continue boil for 4 minutes.

Add 1 oz Centennial hops and continue boil for last 1 minute. (This is a good time to drop in the wort chiller.)

Reduce wort temperature to 170° and add 2 oz Centennial. Completely forgot this step because it didn’t print. :/

Reduce wort temperature to 68° and take OG reading.

Sufficiently aerate and transfer to primary fermenter.

Pitch rehydrated yeast into fermenter.

Allow beer 1~2 weeks in the primary to adequately ferment and cleanup any diacetyl produced during fermentation.

Dry hop with 2 oz Centennial for 1 week.

Bottle and wait another 2 weeks or keg and carb.

Enjoy!
