View Full Version : I think it might be stuck...

OK so I made a cyser last week and I thought it was fermenting along because there were bubbles in the airlock and on the surface of the liquid. In addition, it foamed a lot when I mixed it.

The problem is that when I tried to take my hydrometer reading, I ran into trouble. Initially the hydrometer is rather low in the liquid, reading roughly 1.065 only 5 days after the pitching of the yeast, which I thought seemed a bit fast because the bubbles weren't coming out that vigorously. But after this initial reading, the hydrometer rises for about a minute until it gets back to about 1.120. So I am not sure which reading to believe.

The process and notes thus far are in the brewlog, here is the link to it.

It sounds like it is fermenting. It would help you to know your starting gravity - The Mighty JamesP's calculator is an awesome tool, but it does not take the place of measuring as there can be great variability in honey and apple juice.

To get an accurate reading take your sample and really de-gas it well. You can even microwave it for a few seconds to help. Then take a reading that you feel confident in. I will repeat my gravity measurements more than once, just to be sure.

Then tomorrow, follow the same process and get another reading you can be sure of, and compare.

By the way, what temperature are you keeping it?

I hope that helps,
Medsen

well the temperature in the room is about 60ish give or take a few degrees, I'm in philly to its pretty cold around now, and the house costs a lot to heat so we keep it around 60, but the bucket itself is pretty warm to the touch. I don't have a thermometer that could accurately measure the temp inside the bucket at the moment.

I noticed you said you degas you sample, does that mean you should take your hydrometer reading after you've aerated? I took mine before because I figured the foam would get in the way of my reading, I usually just clean the hydrometer then throw it in the primary as opposed to taking a sample, but I suppose I should start taking samples for more accurate readings.

Yep. At least until you feel comfortable getting good readings.

The 60F temp will keep your fermentation on the slow side. That may be a good thing as you probably retain more volatile aromatic compounds with a slower fermentation. As long as you see it making progress it is fine at that temp. If it stalls, you may want it a few degrees warmer to help get it going again.

Interesting, I didn't know fast and vigorous fermentations were any different than slower ones, cool. Thanks for your help.
