2009 Grappa batches
Posted: Thu Nov 12, 2009 12:32 pm
OK. Finally hooked up with the local winery for their Cabernet pressings.
After the four batches I did last year with Pinot Grigio must, I pretty much have a handle on grappa making without that really nasty bitter taste.
As a recap 5 pounds of sugar, with 3 gallons of pressings and 5 gallons of water with a package of EC1118, a pinch of epsom salt, and a good pinch of DAP made a great grappa. Using 10 pounds of sugar resulted in the nasty bitter taste.
But of course. I got home late after picking up the Cabernet pommace and forgot to look at my notes.
I only decided to do 2 batches this year.
Batch 1: I put 10 pounds sugar, big pinch of DAP, pinch of epsom salt, and a pack of EC1118.
Batch 2: I had just put in 6 pounds of dissolved sugar when I decided to take a break and check my notes! Aaagh!
Well, I didn't want the bitterness to show up in Batch #1 again, so I decided to start ladelling in liquid from batch number 1 to Batch 2 and adding water to even up the volume in both.
So by guestimation in the end, this is what each batch is composed of:
BATCH 1 FINAL: 7.5 pounds sugar, 3 gallons of Cabernet Pommace, big pinch of DAP, pinch of Epsom Salt, and a little less than a pack of EC 1118 and 5 gallons of water.
BATCH 2 FINAL : 7.5 pounds sugar, 3 gallons of Cabernet Pommace, big pinch of DAP, pinch of Epsom Salt, a little more than a pack of EC1118 AND a half cup of the leftover yeast sediement that I have kept in my fridge from last year.
Now another difference from last years grappa is that I am using pommace from Cabernet grapes - the pressing left over AFTER fermentation and pressing. I surmise that there is a lot of leftover yeast on the pommace to contribute to the "second" fermentation of grappa. I also hear that Cabernet makes a good grappa.
Last year, I used the must from Pinot Grigio - the pressings BEFORE fermentation into wine.
An hour after pitching, both batches were fermenting vigrously and blew the tops off both vapor locks!
Several cups of nice red juice came out of the vapor locks as well. Luckily, I set the fermentors in my spare bathtub and the whole bathroom smells like wine.
btw The juice tastes really good and I already taste a little alcohol in there!
