(38) Sunday, July 8, 2012 Brew Day – Kitchen Sink Small IPA

I promised that I would make Gretchen a low alcohol hoppy beer that would taste like an IPA without all the alcohol. Today, I am attempting to do just that. I looked at a few recipes in Zymurgy and BYO and looked at what I had on hand and come up with this recipe to try. It also helps me clean out my left over grain.

Mash Schedule

Mash Type: Full Mash
Schedule Name: Single Step Infusion (67C-152F)

Step Type Temperature Duration
Rest at 152 F 60

Step By Step

7:24 Gas is on. Heating strike and sparge water.

8:12 Overshot the kettle temperature. Was over 180 °F. Flame is off and waiting for the temperature to drop.

8:18 Kettle water temperature is 174. Draining to mash tun.

Note to self. Clean out spigot on mash tun and boil kettle before use.

8:26 Water in mash tun. Temperature is 162 °F.

8:33 Mashing. Mash temperature is 152 °F. Volume is 6 gallons in the mash tun.

Yeast manufactured May 1st. Mr Malty says 49% viability or 49B cells. Recommend 170B cells. Expect a bit of a lag and some stress byproducts.

9:33 Mash complete. Vorlauff and lauter. Mash temperature 152 °F.

9:38 First runnings are 1.067 SG (1.052 SG at 138 °F). Collected 3-13/16 gallons.

9:45 Sparging. Temperature in kettle is 178 °F. Sparge temperature is 163 °F.

9:56 Second runnings are 1.019 SG (1.004 SG at 138 °F). Collected 6-7/8 gallons total (3-1/16 gallons from the sparge).

10:00 Flame on. Heating to boil. Boil gravity is 1.039 SG (1.028 SG at 122 °F). Target was 1.038 SG.

10:27 Boiling. Waiting for hot break to subside.

10:33 Hot break has subsided. Adding 60-minute hops.

11:13 Adding 20-minute hops

11:18 Adding chiller, Irish moss.

11:23 Adding 10-minute hops, yeast nutrient.

11:33 Flame out. Adding flame out hops chilling.

12:05 Chilled to 68 °F. Removing chiller. Whirlpool and settle. Original gravity volume is 5-15/16 gallons. Original gravity is 1.047 SG (1.040 SG at 103 °F). Target was 1.044 SG.

12:46 Draining.

1:13 Drained. Rocking to aerate.

1:20 Aerated.

2:51 Everything is cleaned and put away. Pitched at 66 °F. The beer is in the fermentation chamber with a set point of 66 °F. The thermostat is in heating mode. The set point is the “cut out” temperature. The differential is set to 2 °F. This means that — since the cellar is cold — the temperature of the beer falls until it is below 64 °F (2 °F below the set point). Then the thermostat turns the heater on until it reaches 66 °F (the set point) where the heater cuts out. That means that the beer will ferment at 65 ± 1 °F for this configuration.

Saturday, August 4 Kegged. Final gravity was 1.009 SG (1.010 SG at 49 °F). The hydrometer sample had a nice hoppy aroma but not huge. I guess that is to be expected in a flat beer. The flavor was a bit vegetal. Again, possibly to be expected in a small beer with this much hops at this young age.

Sunday, September 16 Kicked. This was a nice beer. It did not end up as small as I would have liked. Nor was it the hop bomb I expected. Perhaps the alcohol is a larger component of the hop perception than I imagined.
