The Oak Barrel Replica is a simple and perfect way to impart 100% new barrel flavor into wine stored in a neutral oak barrel. 30 staves are tethered into 10 sections, which allows modification and complete control. If you want 50% of new barrel extraction spread over two barrels, simply cut the Replica in half. The contact time is 3 months minimum and up to 18 months of useful life. Toast level is Medium Plus. Comes with eye hook for insertion to a bung. Stavin recommends a wood or silicone bung.
