i only run mine now with low wines (approx 40%, 20L worth) never had this problem. I still use the lower temp as a gauge. I let it hover around 50deg. I find at this temp the output comes out fine (92-93%) no steam.
I have found with mine that this works the best for me
- turn it on and watch the upper temp, turn on the cooling prior to it hitting 50deg. This was most important for me. If i did it to late it was never able to go into full reflux, there would be still a few drops here and there coming out.
- let it run in full reflux for 15-20min, the top temp will have settled in at this point (does for me)
- slowly let the fores and heads come off
- run a little faster (lower temp at 50deg) for the rest of the run.
