Topic
Bar & Spirits
Bar and spirits covers what happens to a drink before it reaches the glass. Distillation and its cuts, time in barrel, clarification, ice and dilution, acidity and texture all sit in this topic.
Two threads run through the list. One follows the spirit from still to bottle and asks what a distiller keeps and what gets set aside; the other follows the drink at the bar, where ice, acid and fat decide how it lands. Either thread can be entered anywhere.
