Myself and my mate have decided to brew our own beer (Kruddler) and we found a decent enough step by step recipe on instructables.com to follow.
We got all of our equipment and all of our ingredients. We followed the steps all the way up to the fermenting process. Everything was going fine, maybe it still is, i'm not sure. This is where some advice would come in handy.
Since Sunday we have had our beer fermenting in my cloakroom. On Monday the airlock was going mental. Every few minutes the amount of CO2 coming out of the fermenter was causing it to pop it's top off. I kept having to replace it and topping it up with water. We have a liquid crystal thermometer on the side of the fermenter and it's showing 22-24 degrees (it was up at 26 when the most activity was happening).
Recently the CO2 has stopped coming out of the airlock. I watched it for a good few minutes yesterday and nothing came out.
I got curious this morning and took a sample to try with my hydrometer and refractometer.
The hydrometer tells me that it's only halfway through the fermentation process (halfway between 'start beer' - red, and 'bottle beer' -yellow) and the refractometer is telling me it's 1.047.
Now, our questions....
Has it stopped fermenting or has it just slowed down?
Will it complete the second half of the fermenting by Sunday (a weeks fermenting at that stage) ?
Will we have to add more sugar to give it a kick start?
Will we have to make the cloakroom warmer?
Do we need to do anything at all to it?
