I have been making wine from grapes (Cabernet Sauvignon - Pinot Noir mix). It had been bulk aging for 4.5 months however there was some left over after I switched from a 6 gal to 5 gal carboy so I put the remaining in bottles. I opened everything today to taste and the wine in the bottles taste great smooth finish. The wine in the 5 gal has a sour after taste. Any reason why this could be?
