P. Sirah at 18 Brix

Punch down continues on the petite sirah. It is fermenting well and
getting less dense. Temp is 63, which is at the minimum for this
yeast. We're getting good extraction.

Brix dropped 2.5 to 18 in the last 24 hours, which is less than the
day before. We have 6-8 more brix to go, which puts fortification
likely on Thursday and pressing on Sat.

We will continue to monitor brix and watch for the 10-12 brix window.
When we fortify we need to mix extra well to stop fermentation.
