This is my very first post...but most likely not my last. I am a beginner, and just started my first batch on Monday. Here's what I'm running into:
I am brewing a Bavarian Hefeweizen from an extract kit I bought. I am using the stick on thermometers and for the first couple of days it's been showing about 68 degrees, but today when I got home it is registering 64. Will this fluctuation in temperature throw off the batch? Should the temp stay constant?If so, what's the best way to keep a constant temperature, and also, how reliable are the stick on thermometers?
