During active fermentation, the beer will be warmer than the ambient temperature of the room, by sometimes as much as 5 to 10 degrees.
OH, nvm, you said the yeast bottle said that. Dunno on that.
hector, we've been trying to help you. But if you don't put the beer in a bottle, let it carbonate and condition then you don't know what it's going to be like. You are trying to troubleshoot a problem before you are even half-way done with the process.
I doubt your contamination is coming...
I don't know about 'deionized' water, sounds like snakeoil.
Your problem may indeed be old extract, but I would guess it's more than likely you aren't giving it enough time to become the beer you want it to be. Doesn't matter how long you keep it in the primary if you dump it before it's...
No he is not the first to talk about an infection. ArcaneXor mentioned a systemic problem in post #26. That means an infection due to poor sanitation. There was a weak link in your process. Please don't 'cherry pick' your responses based on what you want to hear.
Have you kept any batches...
Well in theory yes, that will pasteurize the DME, but what is your recipe? Is is hopped? Are you steeping grains or adding hops? Plus you will still need to cool it down before you pitch the yeast.
There are many other factors to making beer.
-EDIT
Okay, I'm going to assume this is the...
The extract in the can and the DME have already been boiled the extract making process and really only need to be pasteurized (held at or above 140 for about 10 minutes), they do not need to be boiled. And in the case of the Coopers kit, are not designed to be boiled as that would change the...
I prefer light or extra light extract as a 'base malt' and adding steeping grains to make the flavor and color. I know what I'm getting that way. I'm never really sure what's in the darker extracts. But you won't be far off using those, so it's not wrong. You do have to watch SRM and adjust...
