A method for forming a concentrate from an alcoholic beverage, comprising:
- providing an alcoholic beverage including a solids concentration of 20% or less, and alcohol concentration of 30% or less, and water;
- subjecting the alcoholic beverage to a membrane process by which at least some water and alcohol pass through a membrane to be part of a permeate and other components of the alcoholic beverage do not pass through the membrane and are part of a retentate;
