Scottish pot stills 3500L Wash Still & 2500L Spirit Still Including:
the Wash-, Intermediate-, and the Spirit still. See the different sizes and shapes and how the reflux effects the taste of the Scotch whisky.
A pot still at its simplest consists of a large kettle or pot which is heated from the bottom, boiling off the alcohol and allowing the vapors to be sent to a condenser and separated.
Understanding Whiskey Stills: Pots, Columns, Hybrids
There's a lot of attention paid to the way that whiskey is aged. Talk to even a casual whiskey drinker and he or she will likely be able to drop some barrel factoids on you. Yet, the apparatus that is actually responsible for making that spirit, the whiskey stills, are often an area of mystery.
Pot Stills vs. Column Stills
The obvious starting point in any discussion of whiskey distillation is pot stills versus column stills. A pot still at its simplest consists of a large kettle or pot which is heated from the bottom, boiling off the alcohol and allowing the vapors to be sent to a condenser and separated.
With column distillation, the mash enters near the top of the still and begins flowing downward. This brings it closer to the heating source, and once it's heated enough to evaporate, the vapor rises up through a series of partitions known as plates or stripping plates. At each platealong the way, the vapor ends up leaving behind some of its heavier compounds and cogeners.
The most important point of difference between pot stills and column stills is that pot stills operate on a batch by batch basis, while column stills may be operated continuously. This is why they're sometimes known as continuous stills. Further, column stills that are rigged to do so can produce spirit over 95% ABV, nearly pure ethanol, whereas pot stills cannot achieve such returns.
Heating Of Pot Stills：
can be steam powered, direct fire, steam heating coil inside
A pot still heated indirectly, with steam, looks completely different on the inside. The bottom may be shaped slightly conical towards the centre, so that the remains of the distillation (pot ale) may easily flow out into the pipe. Simple serpent-shaped pipes were used for the first indirect heating systems. They ran close to the bottom and the walls in order to retain the heating effect from outside and below, like in the directly heated stills.
Upper Part Of A Pot Still
The still in the picture above can be seen as the prototype of every pot still. The upper part is made up of four basic areas. The first is the spherical lid A, which covers the pot on the upper side. The conical and tall neck C is attached to the lid via the intermediate connection B. The lyne arm E is connected to the neck by the bend D.
