I'm thinking it was more this -- while I try to be careful to run the wine down the insides of the bottle, to lessen the chance of that, there was still a lot of foam -- more than I had seen in previous bottling sessions. That concerned me at the time, as did the fact that the bottles had been sitting for up to a half-hour before I began corking. George and I both thought, given the numerous stirrings of the lees, the numerous rackings, PLUS the scheduled (by the instructions) stirring to drive off CO2, that this was NOT a CO2 issue. Using the vacu-vin was just insurance!
I gave a bottle of my buttery chard to my MIL and she stuck it in the fridge and we noticed last night that it had formed a lot of bubbles in the bottle like OilnH20 described.
What disturbed me was that it looked like soap suds. Here are a few pics, but they do not do a good job of showing how sudsy it looked. When we picked the bottle up out of the fridge some of the bubbles dispersed into the wine I guess.
Anyway... opened the wine and it tasted fine and couldn't taste the bubbles so I'm figuring it's not C02. strange cause if I had introduced air into the bottling process I would have noticed the bubbles then eh?
Wow. That looks much different from the bubbles I had (see the earlier pictures) -- really more like foam than bubbles... you've got me stumped! Time to call in the experts!
if I shake the bottle I'll get bubbles that look like the pic you took, but the bubbles seem to be smaller if the wine is cold and produce the soap suds looking bubbles. I think it's just air
Sang, This is a pic of mine revisited. I forget which wine it was but it was the only bottle out of 30 that did this....and I have to say it was quite good...tasted like Champagne. The cork had a nice pop and bubbled to the last drop.....Actually it was kind of a nice surprise. I checked the others that were left just to make sure I wouldn't come home to wine on the ceiling...they were ok....Weird but Cool.
I wouldn't mind a little bubbly bubbles forming, but I can't detect any CO2 feel - my wineis stillflat at this point. I'll have to keep monitoring and if it starts tasting with a sparkle then cool! (As long as I drink it before corks start popping)
