2.5 oz bag of Hungarian medium plus toast oak beans. Adds a barrel aged flavor. 'Stavin' oak beans are 3/8" cubes of oak that produce superior flavors in wine. They are made with 3 year old air dried oak from Hungary and then traditionally fire toasted. Superior flavor is due to bean density which produces less phenolics and more rounded flavors. Used by many of the best wineries in the world. Use 2.5 oz per 5 gallons of wine. Recommended contact time is 2-8 months.
