A proper Obstler isn't made from one fruit — by definition it's distilled from a mash of at least two, often apples, pears, and whatever else the Alpine orchard produced that year.
Obstler is a clear, high-proof brandy distilled from a mix of orchard fruits, a staple of small family distilleries scattered across Tirol's Alpine valleys. It's downed in a single shot, often after a hearty mountain meal.
