I am following this thread with great interest because I have 4 quarts of Coloma Frozen Foods Peach Juice Concentrate in my freezer just waiting for a few of my questions to be answered.
1) Should I reconstitute to make 5 or 6 gallons from the 4 quarts? Will this be enough to get my peach wine to taste 'peachy'?
2) Does anyone have a target pH that I can achieve with acid blend and an Apera PH60 meter?
3) Is there a target TA I should be looking for, I have a simple acid test kit (Vintner's Best Acid Testing Kit - LD Carlson).
I am planning to basically follow the recipe laid out by minnesotamaker (Lon dePoppe) in this post. PDF in the link.
Peach wine (kit style) by Lon dePoppe
I did find out ( I think) that the Coloma concentrates need to be treated with KMETA prior to starting fermentation by emailing the company.
I emailed Coloma this question:
"I purchased 4 quarts of frozen peach concentrate to make wine.
When I reconstitute the frozen concentrate do I need to add potassium metabisulfite (kmeta) or campden tablets to sanitize the must?
I suspect that the Coloma concentrate process does not kill all pathogens that are detrimental to wine making, but I am not sure."
I received this reply:
" I am Matthew Chudy, QA Director with Coloma Frozen Foods. The concentrate should not have any pathogenic bacteria. However, it DOES have yeast and mold spores in small numbers which will begin to grow when hydrated.
As far as adding a preservative, I will leave it to you the expert to decide."
I sure don't to mess this up!
Any other suggestions?
p.s. I am a fairly new winemaker (Aug. 2020) and am eager to learn the tips and tricks of the experienced winemakers!!
