I brewed a modified Raison d'Etre beer back in June. OG was 1.080, FG was 1.017. This was my first attempt at a higher gravity beer. The yeast I used was WLP510 using two starters.
It was bottled on July 9th with 4.5oz of corn sugar for roughly 4.5 gallons of beer. So far, I've opened 5 bottles and all of them are pretty much carb free. I get a tiny little head on pour and there is some pressure on opening, but no active bubbles after pouring.
I'm thinking about opening all I have left and pouring it in a bottle bucket with some more sugar and rebottling. But maybe my yeast is dead? I have some wine yeast, or some US04 and US05 just laying around. But, will that result in a case and a half of broken bottles? Or will the act of pouring it all out oxidate it beyond measure?
Any advice?
