So this is my first time really brewing a New England style IPA. I have brewed many IPAs in my life, substituting different hops, yeast and grains. Messing with water chemistry. Doing different hopping techniques. You name it. For this brew I wanted to go high on the flaked oats and calcium chloride to get that signature soft mouthfeel that’s true to the style. I also wanted to use the correct yeast. In comes in Barbarian from Imperial. Their website describes it as follows. “ Ready to attack your IPA, Barbarian produces stone fruit esters that work great when paired with citrus hops. Barbarian will give you what you need for an exceptionally balanced IPA. “ To go along with medium flocculation this yeast should work great for the style.
Total Grain (Lbs) - 16.25

24.6% - 4 lbs. Flaked Oats
2 oz. Citra (13.4% alpha acids) @ Flameout (20 min. hop stand)
2 oz. Equinox (13.4% alpha acids) @ Flameout (20 min. hop stand)
1 oz. Mosaic (12.3% alpha acids) @ Flameout (20 min. hop stand)
4 oz. Citra @ dry hop (7 days)
2 oz. Mosaic @ dry hop (3 days)
2 oz. Equinox @ dry hop (3 days)
2 tsp Yeast Nutrient @ 15 min.

04/14/2017 - Made 1.25 L yeast starter on stir plate. My stir plate broke so luckily I work at a brewery and used ours at Community.
04/15/2017 - Brewed with Brian, Nate and myself on my Sabco BrewMagic. Started with 2 gallons of filtered Krum tap water and 4.5 gallons of distilled water for mash-in. Mash pH @ 5 min. 5.85. Added 10.2 grams of Calcium Chloride, 1.4 grams of Gypsum, 2.3 grams of epsom salt. Mash pH down to 5.7. I figured I’d wait until we raised up to the 155F rest to check again. I added 1.5 ml of lactic acid. pH down to 5.45. Left as is. Sparged with 1.3 gallons of filtered Krum tap water and 2.9 gallons of distilled water (added 2 ml of lactic acid to bring down pH). Collected 8 gallons of wort for boil. We did not have to dilute because our runnings never got below 2.5 Plato. Pre-boil gravity measured 1.058 (15 plato). Chilled to 68F and whirlpooled for 20 min. Collected a little over 5 gallons in fermenter. Added 30 seconds of pure O2, followed by the yeast starter. Set the SS Brewtech temp. controller to 64F.
4/17/2017 - 8 PM - Upped the temp to 72F. Gravity = 10 Plato.
4/18/2017 - Added first set of dry hops, 2 oz. Mosaic & 1 oz. Equinox.
4/22/2017 - Added second dry hops, 4 oz. Citra. Gravity = 3.5 Plato (1.014).
4/24/2017 - Crashed. Gravity = 1.014. 7.4% ABV, 79% Apparent Attenuation.
