Hi there - I'm brewing an IPA with Wyeast 1056 American Ale Yeast (optimal 60-72 per the packet) and have my primary in a swamp cooler b/c my apt is too hot, sitting comfortably in the mid 60's. This morning I went to rotate my ice bottles and noticed the airlock overflowed, even with the temp at 66. I had no bubbles for the first 48 hrs, so it appears the yeast went hyperactive between hrs 48-54? I removed the airlock, re-sanitized it in Star-San, cleaned up the top as well, refilled the airlock with Star-San, and it was bubbling nice and slowly as expected, say once every 10-15 seconds. Going forward I'll use a blow-off tube and either a bigger carboy or just less volume, but should I be concerned about this? The yeast formed a good seal around the airlock, so I don't think anything could have gotten into fermentor. Thanks for any assistance.
