Bravo -- curious what your port making protocol was?
Freeze all the fruit, take out of the freezer the day before pitching yeast. At sugar addition it will still be very cold.
Simmer raisins/prunes in water, just enough to cover the fruit. Add to the fermentation bucket.
Simmer equal amounts of water and sugar with a tsp of lemon juice (helps break down the sugar). Add until the desired Brix is reached. This will raise the temp of the cold fruit quite a bit.
Add Kmeta, tannin powder, oak chips, pectin enzymes, etc.
Make a yeast starter, see
@winemaker81 method for making a starter. Pitch after 8-16 hours, I can’t seem to wait 24 hours.
Avoid stirring for 12 hours, then stir 2-3 times a day, measuring Brix each time.
Add Fermaid O at approx 1/3 sugar depletion. My ferments have been so fast I’m thinking I should just add FO after 12-24 hours. My last ferment got to 1.010 in 48 hours.
Press at SG of 1.010, transfer to carboys with an airlock.
Ferment dry with rackings every 3 months, add Kmeta.
After the first 3 month aging, add chocolate powder. Add Everclear 190 to convert to a port. No Kmeta needed. Use the Pearson Square method for adding the EC190.
After approx 1 year of bulk aging, back sweeten as needed, or back sweeten at any previous rackings if you wish. Blend in any grape wine you want to.
Rack to your bottling bucket, add glycerin, bottle.
