Leopold Bros. Absinthe Verte is grape-based (essentially the varietals commonly found in Chilean pisco).
Once the spirit is distilled with a variety of botanicals and herbs, including grande wormwood, flannel and green anise, the Absinthe Blanc is racked in used French oak barrels to rest. After a period of time in the barrel, the spirit is heated in a stainless steel container to a temperature below boiling, and a cheesecloth bag packed with roman wormwood, hyssop and lemon balm is placed in the container.
The chlorophyll from the botanicals colors the absinthe green or verte. From there, the spirit is bottled and numbered by hand.
