Barrel aging is crucial for wine structure, aroma, and complexity. However, barrels are expensive, take up a lot of space, are inconsistent, and are often unsustainable. Wineries need a cost-effective, controlled alternative that still provides the sensory quality of premium oak integration without requiring physical wood contact.
Wine i-QT™ offers a solution by delivering pure toasted oak tannin, extracted from 100% European oak heartwood, to replicate the phenolic integration and oxidative buffering traditionally achieved through barrels or staves.

Wine i-QT™ is a toasted, soluble oak tannin powder. It is derived from 100% heartwood of European oak. The oak is gently toasted before extraction. This product contains no bitterness or harsh phenolics, offering a smooth, integrated expression ideal for oak mimicry.
