I'm still VERY much a newbie to this craft, so please bear with me.
I recently got a reflux still from Keggomax. Yes, I know it's not the best still out there but I thought it's a way to start. Anyway, I was doing my third run with it, fired it up and let it stabilize for around 20 minutes. I then ran my fores and heads and then I had to leave for around 15 minutes, so I left it running but stopped the alcohol take off.
When I returned I was surprised to see that the temp had dropped about half a degree. Why would this happen? Insufficient time to stabilize?
Any ideas?
