i've done something kinda dumb i think. with my 6 gal carboy full (wine ready to bottle but no bottler), i started to drink off it (not directly!!!) so that by the time my bottler came it had been sitting roughly 1/3 empty for about 2 weeks.
finally got the wine bottled. the next day my friend opened one of the bottles that he took home with him and he told me that he thought it might be turning.
so i uncorked one and noticed a what is kinda a slight sour taste, but not really. i'm hoping that it's all just subliminal. something that i'm looking for.
since then, i stuck my 6 bottles (all i had left from my portion of the 30 bottle batch-- friend got 15 bottles) in a little refrigerator in hopes of halting any potential "turning."
what do you guys think is going on?
hoping that when i had the big air space in the carboy, the wine didn't oxidize...
