I have been trying to find a way to get the proper/exact readings for my batches,but it seems to be really difficult to correctly take readings at home.
My main problem is the temperature. The moment I take a little bit of the batch, it obviously starts warming up (since the temperature of the batch is slightly colder than room temperature.....I keep it in the closet).
This means that the reading will change as the temperature affects the sugar in the small amount of liquid I take out of the batch. My idea is to put the thermometer and the hydrometer together in the liquid and jot down both the reading and the temperature, but is there like an excel chart to help me with the connection between the temperature and the reading?
Anyway...here is what has just happened....we have bottled a batch (IPA made from extract)...I took the the reading before the bottling and the room temperature was 21ºC (70F) and the reading was 1.015. 1.015 is just okay for bottling, but the batch fermented for 3 weeks at 18-19ºC (65-66F). No way that it wasnt ready for bottling.
As the little amount of liquid warmed up under room temperature that 1.015 reading started to drop to 1.014-1.012.
Any ideas how to improve my techniques? My lack of knowledge is annoying the hell out of me.
