I had earlier in the day place a brew belt on it to warm it up, in order to degass one last time before bottling....
I have used brew belts on all my glass before and never had a problem....The wine was siting at about 65 degrees.....
So sad....It was an EP Cab Sav, bulked aged coming up on 1.5 years, with an extrea 3 oz. of oak.....What a shame....
