So I made my first brew yesterday. I went with an extract kit from MoreBeer, the American IPA. Took my OG and wound up with 1.072 which I was very surprised at. Expected OG was 1.054-1.062. Anyway, poured in my yeast and placed it in the closet to ferment. Checked it last night and it was happily fermenting away. Stick on thermometer read at about 70, my house sits around between 66-68 so there's not much I can do about the temp. I didn't rig a blow off tube as I was just following directions and hadn't heard of that yet. So, to the problem. This morning I check on it and apparently the activity was so high throughout the night that it overflowed into the airlock. Nothing major, just a little spillage on the top, but I have wort in the airlock now. Should I empty that out, and resanitize or can I leave it the way it is. I figure the damage if any is already done. The airlock was sanitized inside and out prior to its installation.
