So dh had a poker party and had 2 kegs of microbrew. They are both tapped and have the little party pump button on top. The Hefe is almost gone but there is lots of Red left . I filled 2 growlers that we had on hand but will the rest go bad right away? Its unfiltered and I tried to look on line for info but honestly I am confused with the brewer sites because I think they mean long term storage of a keg that has never been tapped. I am guessing they will be useless once they warm up?
It was probably bad by the second day I had a glass and it gave me HORRIBLE stomach gas lol . I also talked to a brewer and he said 48 hrs and he wouldnt drink it .
Sounds like you got a belly full of yeast sediment. An issue that sometimes comes up with home brew and unfiltered/bottle fermented beer is that the extra brewers yeast, much of which settles to the bottom, can be resuspended if the container gets agitated. That extra yeast can cause a serious bout of gas. Any home brewer who touts the taste of his/her beer and swirls the bottle before pouring it either has an iron stomach or just doesn't like you much.
With bottles, you can generally let them sit for a few days and the yeast will settle again. Unfortunately, growlers will go flat and taste "stale" after just a few days, so there really isn't a ton you can do to allow the yeast to resettle.
When drinking unfiltered beer, I recommend pouring it into a glass while trying to leave about 1/4 inch of beer in the bottle as garbage. Might seem like a waste, but your tummy will thank you. Your palate will love you, too, as the suspended yeast can cause the beer to taste "off".
Also worth noting, cloudiness in your beer doesn't mean that its been stirred up. Many unfiltered beers have a cloudy color due to some yeast suspended, but, unless you have a disposition for it, it shouldn't be enough to cause any discomfort.
I hope your experience hasn't turned you off from home brew and micro brew. There is such a huge variety of flavors and styles (both filtered and unfiltered), everyone the least bit interested should easily be able to find their own niche.
