I made a brown ale on Thurs (I didn't entirely intend to, but that's the joy of learning about steeping grains!). It went in the bucket on Thursday night at just under 1.050, and I sent in my SO4 yeasties. Sunday night I was brewing wines and ciders and things, and I took a little peek. There wasn't much sign of activity, so I thought since my hydrometer was sanitized, I'd check it. Lo and behold, it had dropped just just over 1.010. Is fermentation at that speed common?
