Hi All,
I'm in-experienced, so don't mind me, but what I have found that helps my homebrew not to taste like the homebrew Mattybabsy is referring to is :
[a] Don't follow the kit instructions, don't just dilute it with hot water and chuck yeast. Put it in a big pot that can take your full run, or at least say 60% of your brew, boil it a bit, not too much, and stop boiling before it goes darker. Try and use mineral water, and a lil bit of hops won't hurt either.
Chill your hot wort rapidly, even if you only use cold water and ice, to force the cold break to settle out, and make sure NOT to add the cold break solids back into the brew.
[c] Use a yeast starter, pref, feeding on the same wort at the same temp as your planned pitching temp, then you ensure they hit the ground running and are not shocked. If you treat your yeasties well, they return the favour.
[d] Try and keep the fermenting temp as constant as possible. A small closet with lotsa towels works well.
[e] Don't be hasty, leave it for at least 2 weeks. Even if it's obvious that it's done fermenting. Those yeastys are still hard at work, even if it don't loook like it.
[f] (prolly be crucified for this one) try and give the secondary a skip. Leave it on the trub for a while, with a good yeast, 28 days at 14`C or about 21 days at 20`C should not have any negative impact. It seems as if the yeast cleans up alot of the bad tastes like this and also seems to reduce the bad hangovers I've had from others' homebrews dramatically.
Try these steps once and I am relatively sure you'll get rid of that homebrew tang, and end up with a product surpassing your expectations in quality. Yeah I know it's alota work and so on, but to me, it's well worth it and has only paid dividends for me. :drink:
