I just brewed my 16th batch since Christmas and think I am getting the hang of this home brew stuff, but I'm seeing an odd behavior and am worried about the beer I brewed on Saturday. Here's the variables:
1. Used Wyeast 1007. The expire date was a few months ago, and I had it out for last weekend. It puffed up but I had to toss it back in the fridge before pulling it out again Thursday night for a Sat. morning brew. It definitely puffed more from Thursday to Sat, so that's a good sign right? www.byo.com has it listed as a low floc yeast, so maybe this is common for these? I don't use a lot of low floc yeasts.
2. Mixed my StarSan last week with distilled water. Read on here that as long as it's clear, it's still good. Is that true, or did I just ruin my beer by not mixing fresh? It was as clear as the day I mixed it so I assumed it was good to go.
The rest of my procedures were the same as usual, but I'm not seeing any activity in the airlock. Now, before everyone goes nuts on me...I understand that it could be fermenting fine without firing any bubbles, but in my 16 batches it's been rare...so I worry.
Right now I'm thinking it's a more mild yeast and that's why, but who knows? Not every yeast needs a blow off tube, but most I've used do show me they are working at least.
Anyone with any wisdom to share?
