I've had a run of bad luck with my beers lately. The Brown Ale I did a while back seems to be infected and the Ordinary Bitter I did last weekend is really infected. I mentioned this to Rich, a fellow homebrewer, and he pointed out that this was one of the reasons the Germans started lagering their beers during the summer. They found it hard to actually brew anything during the warmer months. Of course now we know that it is because of the higher amount of infectous bacteria in the air during the warmer seasons. I've come to the conslusion that I will either have to stop brewing during summer (nooooo!) or find better ways of keeping my un-inoculated wort away from the beasties that would love to ruin it. This last beer that I did I had a big issue with wort chilling. I chilled it down to 100f with my immersion chiller but after that it wouldn't drop. After I waited about 45mins for it to drop I decided to just cap it off and stick it in my fermentation box and let it cool. I came back down after about 3 hours and it was still at 80f. So, I pitched my yeast and closed it up. The yeast was a little suspicious as well. Usually when I just pitch a vial (OG=<1.040) I will just put the vial in my pocket and vent the CO2 every hour or so while I'm brewing. This vial never built up any pressure. I think the vial must have been exposed to some high temps while in shipment to my LHBS since it's "use by"date was Aug '07.

My plan is to attempt another English beer this weekend, probably a Dark Mild or an ESB. That is if I get my chilling techniques down. I want to use a sump pump in a bucket or cooler of ice water to push water thru my immersion chiller and adding a ball-valve with a "hop stopper" like item on the inside to filter out the hops (I'm using leaf hops).

We'll see how this beer comes out. If it gets infected I may just have to stop brewing during the summer, or switch to extract brewing and return to the kitchen for a few months.

    It sounds like this infection had a number of causes. Not only is the bacteria count quite high given the weather conditions, the very high pitching temperature most likely had a detrimental effect of the viability of the yeast (which was already in question). You may want to consider getting a pre-chiller for your immersion chiller to increase the temperature differential between your wort temp and the chilling water temp.

    Hope the hot & humid weather breaks soon and you're able to stat brewing productively again. Best of luck!
