Steam vs. Ozone

Preserve What Makes Your Barrel Valuable

Wooden barrels are more than storage vessels. They actively contribute to the maturation of wine and spirits through the gradual release of aromatic compounds, tannins and structural elements from the oak.

Repeated steam treatment can expose the barrel to heat and moisture and may gradually remove desirable wood components from the pores. OENOCAT® uses ozone gas at ambient temperature and therefore provides hygienic treatment without thermal stress on the wood.

Frequently Asked Questions

Does ozone damage the barrel?

No. OENOCAT® uses ozone gas at ambient temperature and avoids thermal stress on the wood.

Can ozone replace steam?

For many sanitation applications, ozone provides an effective and significantly more sustainable alternative to steam.

Does ozone affect the flavour contribution of the barrel?

Unlike repeated steam treatments, ozone does not heat the wood and can help preserve desirable oak compounds that contribute positively to wine and spirits maturation.
