Infection! My last 2 batches of all-grain beer had been getting infected, and I'm seriously wondering why. Thankfully it's only a Brettanomyces (wild yeast) infection, and not bacterial - it's safe to drink, just that aesthetically it's awful with bits of yeast floating at the top, and I lose control over the original yeast's flavour profile. Brett is not always bad though, as it can add some depth and character, but I'm going to try to find out why they've been infected. I'm suspecting one of 2 things - the spout from the brew kettle (where the wort exits the brew kettle into the fermenter), or the tea bag which I use to dry hop in. For the next batch, I shall sanitise the spout (oversight on my part!) and also soak the tea bag in sanitiser first.

Back to Bee Cave's ale - remember the low starting gravity and hence the low alcohol %? Ah. I actually brewed to my usual 23litres, but just re-read the recipe and found that it's for 20litres! One of those Duh! moments.
