I have 23 gal chilian shiraz from juice pails and grapes that has been vacuum racked twice and in demijohns bulk aging since May 2016 tonight i grabbed some with a wine thief put in a glass with 1/4 tsp K-Meta and it fizzled like it was just finished in the primary I took another sample out of each of the other demijohns and they were just as gassy I tasted a couple more samples and they are all the same. So at this point I vacuum racked all the wine out and then back into the demijohns then sampled again and it still tasted real young. I have drank shiraz made this same way and never had this happen before does anybody have an idea why this would be I used RC 212 no MLF no oak and k meta every 3 months. PH 3.27
