New to this site and already very impressed by the knowledge and helpfulness here.
Allow me to bump this tread as I am in a similar predicament!
Just about to start using a 600liter (160ish gallon) electrically heated still with an 8" column with 8 plates. From reading this thread I now have doubts if this is sufficient to make a good neutral. The plan is to strip to around 50 proof and then a spirit run. The goal is Vodka and Neutral to be used for Gin production, all made from Barley and Wheat.
If the 8 plates isn't enough I believe I would have to extend to column above the plates and fill it with SSP's. The question is, would it help and how much extension would I need?
