We bottled 10 gallons of an oatmeal stout back in July.
The first few bottles I remember having were amazing. Then I let it sit for a while because it was summer and hot and not much of a stout drinking weather.
Now…the last couple dozen bottles I’ve opened are way over carbed. Like…the beer foams out of the top and I have to let it sit in the sink for several minutes before I can pour. I’m lucky if I get half a bottle out of it.
There is a ton of sediment that settles in the glass too.
This could be because the yeast at the bottom got disturbed upon gushing…but it looks like there is more than there should be.
We’ve always been careful to measure just over a half cup of sugar (5/8) per 5 gallons…so I don’t think we added too much sugar.
My other thought is some sort of infection…but the beer tastes fine…so I don’t know.
