Brew #49 – Sour Mash Berliner
Based on the recipe here.
09/18/2013 – Sour Mash
3 lbs – 2-Row
1 lb – Malted Wheat
0.5 lb – Malted Rye
2 gallons of strike water at 161 degrees F. Mashed at 152 degrees F for an hour. Cooled to 120 degrees F by adding 1 gallon if cold spring water. To inoculate, added:
0.75 lb – Un-milled 2-Row
Covered the surface of the mash with saran wrap and floated CO2 on the surface. Soured mash at 110 degrees F for 72 hrs.

During the souring, some fuzzy stuff grew around the edges where the Saran Wrap did not cover. Most of the area under the Saran Wrap had a white pellicle growing. The smell was very similar to tomato soup. Not a very strong smell.
After removing the Saran Wrap and skimming the pellicle, the mash was strained through a grain bag. I squeezed most of the liquid out, but did not sparge.
45 minute Boil
1 lb – Light DME
0.5 oz – Hallertau hop pellets (15 min)

Fermented with Wyeast 1056 (American Ale Yeast) from Brew #48. Dumped most of the trub from Brew #48 down the drain, but reserved approx. 2 cups to inoculate this batch.

Extremely clear now. Fairly tart… I think this will be a good one.
