I can nail a recipe (that I like) pretty much 100% of the time, I do sometimes fail on pleasing other people but I consider it a massive fail when I get an infection. I could be trendy and call it a "Brett inoculated beer" but I choose to pour the beer down the drain. I've had a few of those recently and I've not definitively identified the cause which is most worrying. I've scrubbed out and repainted the beer area so hopefully....

I am lucky in that I just do not have a fermentation temperature problem, others will have to make use of a brew fridge or similar, but, if you are keen to make good beer then you should get one.

Depends on how keen you are....

Read this and see how committed http://news.nextglass.co/beer/beware-ho ... ery-slope/ :-)

I am going to have to totally disagree with this. Fuck styles and fuck the BJCP (apart from competitions). If you only brew to style then you are missing out. However you can go too mad and make Lavender wheat beer and that sort of stuff is just sad and wanky.

I'll just chuck up one other major problem. The drinker. Sometimes it's too easy to get too analytical about beer, to the point that some people seem to be no longer enjoying the simple pleasure of drinking beer.

I agree, but brewing to style is no the issue, making decent beer is.

Again agree with this up to a point. But I'm interested in what causes major off flavours and how to fix them. Not minute analysis of intricateflavours etc, but the problems that stop a healthy percentage of homebrew from being drinkable.

Not necessarily; plenty of yeasts are pretty happy at a range of temperatures in certain styles.

Agreed. The mauribrew yeasts that are popular in Australia are perfect in our summer months when other yeasts crap out.

Not putting fermenters in airing cupboards or in front of central heating radiators would be a great improvement :-)

Er, that was the point, these were from the NHC so ideally, the brewer should have thought.... these are being judged against these guidelines, I should brew my beer in line with them.

I do agree that sticking to guidelines outside of this is not a good thing and is not something I do. however, I do ask that......please, please, please no more beer with citrus hops and mint. It does not work!

Citra and mint, for the love of baby jesus, just say no!

Nobody should have issues creating fairly balanced recipes, read some books, take some advice.

Nailing bloody infections is a bugger though. Why do we have so many as home brewers, it doesn't seem to happen to commercial brewers.

I don't think homebrewers do have so many infections. Modern sanitisers and half decent practice should see you right - as long as your yeast is healthy and pitched in sufficient quantity.

I would say it's much easier for an infection to take hold in 25 litres than in 2500.

Up to a point maybe, but aren't pros more likely to ensure they pitch the right amount of healthy yeast? An underpitch or poor quality yeast leaves you wide open whatever quantity you brew.

I think Bob has a point, the levels of infection required to screw a 10bbl batch would need to be high to begin with, especially if the bugs have to compete with an amount of yeast which is pitched to ferment a batch of that size.

I suspect that many commercial brews are infected to some extent, it's just whether or not the size of the infection is detectable in such a large volume.
