Poire Williams is a colorless eau de vie made from the Williams pear. It is generally served chilled as an after-dinner drink.
Many producers of Poire Williams include an entire pear inside each bottle. This is achieved by attaching the bottle to a budding pear tree so that the pear will grow inside it.
Williamine is brand of Poire Williams; the trademark is owned by Distillerie Louis Morand & Cie, who distill the drink on their premises in Martigny, Canton of Valais, Switzerland from nearby orchards.
