Thanks to this site, I'm embarking on my first wine making from Brehm frozen must. I'm picking up 3 pails of cab sauv and 1 pail of cab franc. I'm going to ferment all 4 pails together in a Brute trash can. I have a new press ordered, and I'm excited!!
I still need to order yeast and nutrients. I found a starter pack online with nutrients that are associated with these frozen pails. Do I need some of these nutrients such as: Fermaid K, opti red, Go Ferm, Ft rouge, Lallzyme EX??
Any suggestions for yeast? ICV 254 or MT is what I was thinking so far, but am open to all suggestions as I'm a newb.
My grape winemaking has been exclusively from frozen must, and I've utilized the Brehm products as well, and have been quite pleased.
As far as what you need, you have a good start with the Brute and the press, and I'll share my typical protocol for well extracted reds, and what you may need along the way. My experience with the frozen Brehm must is that extraction of tannins, color, etc. is excellent due to the freezing / thawing / cold soak, but I add EX, probably overkill......... and have never had a tannin shortage and needed to add any tannin products. The color has always been fabulous.
I don't sulfite frozen must, just let it warm up slowly, and add Lallzyme EX after all of the ice is gone, mix gently a few times a day as it warms. Make your adjustments (BRIX / Acid) during this time (assuming you have testing ability???), make sure you warm your samples to room temps. If you'll share the BRIX, pH, and TA of the must you are purchasing, I'd be happy to tell you what to plan for if the numbers are the same on your must when you test it. Tartaric acid or Kcarb may be needed in the acid adjustment, water or sugar if the BRIX is too high / low.
Once it hits 55F, add yeast, and my preference is BM 4x4, sprinkled on top.
When the first cap comes up, add first dose of Fermaid K, followed by MLB inoculation (VP41, rehydrated with ActiML, and the MLB nutrient dose OptiMalo). Some folks don't add MLB until after pressing, I prefer it when there is little alcohol and higher temps from fermenting. Personal choice.
Punch down gently as frequently as my life allows, which is 5 or 6 times a day on weekdays, maybe 10 on weekends. Add second dose of Fermaid K when SG reaches 1.050 - 1.060 range.
Try to press around 1.000 +/-, then rack off of the lees 2-3 days later, let AF and MLF finish (need a testing mechanism). Rack and add SO2. Age, rack, clear, oak for a year or so. Bottle at a year or longer, drink in a couple of years.
