ljcjd... i'm having the same problem... i've been whipping mine for the last two weeks, (6 days total of whipping for 3-4 hours at a time)... i junked the wine whip to try a mixx-stir, but same results... if i stir at the bottom, it's fine, when i bring the mixxstir toward the top of the carboy, foam comes up every time... i think i have a carboy of CO2 disquised as wine... what is the Bottle test??? i shook store bought wines, and even they bubble when i shake them, even though they are flat wines.... also i pulled out a bottle and a half of wine from my carboy last night, if i am going to degass every night, do i need to top off every night or will it be ok not to top off for the next few days???
