Description: Sonnema Herb vodka is a grain vodka (a combination of corn, wheat, and rye) filtered through charcoal and infused with an herbal blend that is said to hearken back to the 1700s by Hendrik Beerenburg. The exact mix is secret but is admitted to contain wormwood, rosemary, gentian root, and juniper. The flavored vodka is actually inspired by gin (itself, an herbal infused vodka) in the genevere Dutch tradition.
