What kind of attenuation can be expected from an extract kit?

McDingleberry said:

I brewed the IPA extract kit from Northern Brewer about 10 days ago. The kit says that the OG should be 1.064, which I hit exactly. Unfortunately, the kit doesn't say what the FG should be. The bubbles in the blow-off slowed way down on Saturday so I took a reading just to see where it was. It was 1.015 and now 3 days later it hasn't moved. I was hoping to get down closer to 1.010, but I just don't know if that's normal or not for extract kits. Should I be happy with 1.015? It tastes awesome by the way.

1.015 is pretty low for an extract kit with an OG of 1.064. An identical gravity reading three days in a row is a good indication fermentation is complete. You could enter the ingredients in something like brewtarget and get an expected OG/FG, but that sounds like a successful fermentation to me.

All the NB extract kits are like that. I have done 5 so far, and none of them tell you what to expect as a FG. I just give it a month, then take a couple samples a few days apart to make sure it has stabilized before bottling.
