Oak Infusion Spirals® 8″ Infusion spiral, for imparting wood flavor/character in beer or wine. The Oak Infusion Spiral releases fresh, new-barrel, toasted oak aroma and flavor through its patented, spiral-cut design. The abundance of cross-grain exposure speeds extraction of oak compounds 8 times faster than conventional parallel-grain exposure associated with barrel staves, inserts, sticks and chains of oak. Spiral-cut design also enables oak to submerge quickly into wine, minimizing exposure to air while creating more layered complexity. Use one spiral for 3 gallons. 6 weeks contact time for full flavor. Set of two.
