This still performs the first distillation of the wash to an intermediate spirit called low wines.

This raises the alcoholic strength from 5% to around ***%.

Each 2,500 gallons [11,400 litres] of wash will produce 500-600 gallons [2,300 - 2,700 litres] of low wines which are next redistilled in the low wines still.

The residue is known as Pot Ale or Burnt Ale.
