Brewday recap: Dark Lambic #2 (pLambic) with Turbid Mash

DSCN2243This post is long overdue, but needed to be written. The weekend immediately following Lambic #1, I prepped a second wort for a sour pitch. I had an ECY20 pitch sitting in the fridge that needed to be put to work.

I made a starter several days before, as the yeast had been refrigerated for 2 months. The starter took off right away, and had a much funkier (barnyard) smell than the ECY01 did. This would prove to carry over to the primary fermentation as well.
DSCN2248After some serious waffling and consulting, I decided to brew a darker wort than the first lambic, and also to give it a little more food. I still followed the turbid mash technique, and used a good bit of unmalted wheat. What I’m hoping for is a wort profile similar to an Oud Bruin, but with a much more complex flavor profile due to the microorganism cocktail from Easy Coast Yeast.
DSCN2246I filled my brew kettle to the rim as with the previous batch, and there was so much wort that I actually needed to boil it down some before I could add all the second runnings. Partly why I got such a high efficiency, but also makes for a really long boil (and uses a lot of propane).

DSCN2249The primary fermentation happened fairly quickly, and there’s now some lingering bubbles on the surface, along with a very barnyard-y smell from the airlock. Time to put it away and forget about it for a good, long while. I will be adding oak in a couple of months, but there’s really no rush on that at all.
