Neutral spirit types of alcohol need filtering and are most often produced in a continuous still. The purpose of a pot still is to bring the flavors over to the resulting liquid. Any flavoring to neutral spirits is is infused in a "Gin Box" right before the steamed vapor is condensed, or it is added (infused) to already distilled spirits.
A fractionating distillation column is the best solution for making strong alcohols. Such a column can produce pure 95% alcohol in one operation. A fractionating column contains a number of plates or trays ( each plate spans a portion or fraction of a column). These plates function as containers where separation of alcohol occurs. Each containe
Called a forced reflux still. Unlike pot stills, reflux stills are designed to create higher proof with little to no flavor alcohol. Inside the still is a column that allows the reflux of liquid to help condense the rising vapor and increase the efficiency of distilling, thus increasing purity. The taller the column and the more reflux liquid will occur and the more neutral the alcohol will be.
Filtering only for pure spirits that are typically distilled several times, that are typically distilled in a continuous still with many bubble plates.
