Hey guys! Been very busy, but still managed to find a little time to do a little mini-study on something that’s been poking at my curiosity for a while. Namely it’s the question of water vs wort and temperature range when rehydrating dry yeast.
According to easily available data around the internet, rehydration in water is the way to go. However no concrete numbers are ever provided, which makes it difficult to convince “no rehydration believers” that there is any difference. Also you don’t even know if it really makes a difference or not. So I decided to take a look at the issue.
The results seem to agree with the “warm water is the way to go” point of view. Obviously this is not dogmatic and if you disagree or doubt, by all means do your own thing
