This is my very first brew. I put a really small amount of beer (4 litres) into the fermenter (I live in a small apartment and I found a recipe for 5 litres - I tried that) on Saturday afternoon. The following day the fermentation activity was high, but on Monday it became slower and approximately since Tuesday morning the airlock is still. I swirled the fermenter for a minute, but then it didn't really help. I read about the symptoms and I found the following assumptions:
- Maybe there is something wrong with the temperature - I use Mangrove Jack's M41, which requires 18-28 celsius degree (64-82 in fahrenheit) and the temperature at home is 23-24 celsius all day and night. So I think this should not be the problem.
- Maybe the yeast was too much
- Maybe the yeast was not enough or too weak
- Maybe there is no problem, just chill
I'm not sure if I should not do anything or add more yeast. Or do not make a decision before any gravity measurement?
If I buy a hydrometer and measure FG (recipe says 1.006) and it is relatively high, what is the best I will be able to do? Yes, I know that the best would have been if I measured OG at the beginning. Now I see that it was a big mistake of mine, but the recipe did not warned me about the importance of gravity measurement. And as this is my first try, I'm not concerned about exact alcohol % - I will be happy if the result tastes like a beer.
Thank you if you read this and try to help me!
