The Smartest Oak Alternative: Large surface area, tiny footprint solves high cost, hassles of new barrel. Dual-grain exposure speeds extraction and submersion with refined and integrated results.

"...maximal exposure of the cross-cut axis of oak pieces will result in a much more rapid extraction of flavor compounds into wine."  --Practical Winery Magazine, December 2010

In 2005, we introduced a smarter oak alternative that delivers efficiency, economy, and elegancea product that fully extracts in weeks, not months, adds new oak impact at low cost, and integrates with wine with a refined quality that rivals an oak barrel. We engineered a low-cost method of forming a precision spiral cut into premium oak that maximizes grain exposure in a size small enough to fit through a bung hole. Our convection oven toasting permits optimal control of temperature exposure, timed for uniformity of depth. We contain and connect six Oak Spirals inside a food-grade, nylon mesh that makes insertion and removal clean and trouble-free. The Oak Infusion Spiral's fast submersion in wine gets extraction started immediately, completed in just six weeks, triggering early onset of the wine-oak integration process. The Oak Infusion Spiral is made in bung-hole size as well as tank size and available in French, American, and Eastern European oak. The Oak Infusion Spiral is designed, patented and manufactured in Avon, Minnesota, by The Barrel Mill.
