Second brew: Fermentation has gone quiet
Hi there,
I am fermenting my second extract brew, and its been very quiet compared to the first batch. I am using the Rocker kit, and followed the recipe exactly the first time. The pressure in the FV was always high.
The second time I followed the recipe the same, except I topped it up to 21 litres rather than 19, and I added some dry hops. The pressure was less to begin with but it was definitely going - I still got a load of foam and the airlock was lopsided.
I opened up the FV to add a bunch of dry Hops after 3 days I think. After that there has been no pressure - the airlock is level. It seems no CO2 is being generated at all. I used 21 litres rather than 19 so the gravity reading I took of 1.010 just now (after 1 week) sounds about right (I assume that if the gravity should match that in the Way To Amarillo recipe as I am using the same amount of extract/water). Incidentally, I managed to muck up the initial reading somehow as I got 1.024 but later realised it should have been about 1.050!!! Not sure how I managed that, but according to the Way To Amarillo recipe I can't understand that reading.
So I am hoping that it finished fermenting after 3 days, although this seems very quick. Or do you think its gone dormant for some reason? The temperature is always between 17 and 21 degrees in the room so that would seem a bit strange.
Any help much appreciated
Cheers

1010 is done, or there abouts so fermentation was quick for this one. Sometimes you find that a beer ferments quicker or slower, theres lots of reasons, pitching rate, viability, temperature, oxygen etc etc.
Keep checking the hydrometer over the next few days to make sure fermentation has finished though.
Very strange about the first reading, maybe the hydrometer had some bubbles stuck to the bottom, this could change the reading as 1024 is low.

Loads a beer after an upgrade!
