Boompjes Korenwijn is our 4 year old barrel aged Korenwijn. We produce this genever with 60% maltwine, the key ingredient to any genever. In our case, it’s made with rye, malt and corn for extra flavor! The law stipulates that Korenwijn has a minimum of 51% maltwine. Ours is at 60% and provides a hefty dose of malt-action to work in cocktails, mixed drinks or just straight up.
