Winemakers must sanitize winemaking equipment properly to maintain the wine’s quality. Traditionally, winemakers relied on chlorinated materials, trisodium phosphate (TSP), and soda ash solutions to sterilize barrels and tanks. However, contemporary winemaking has shifted towards safer, more effective methods, such as winery steam. It offers a sustainable and highly effective alternative, addressing critical concerns and setting exceptional sanitation standards.

Elimination of Chlorinated Water for Sanitization
Traditionally, winery sanitation followed a simple path—using TSP, chlorinated solutions, or soda ash solutions to clean barrels and tanks, then washing it down with chlorinated water. However, winemakers discovered that trichloroanisole developed in the wine when specific bacteria fed on chlorinated water, resulting in contaminated ‘corked’ wine. This contamination could originate from corks but also sources in drains, barrels, tanks, and even wood and cardboard materials in cellars.
In response to this revelation, chlorine-based cleaning products were phased out. Companies pivoted towards ozone treatment and dry steam sterilization, alternatives to upholding stringent hygiene standards.
Why Steam Is Better for Winemaking
Steam cleaning has emerged as an advanced and eco-conscious technique in sanitizing wine bottles and equipment, offering numerous benefits compared to traditional cleaning methods. For example, steam can reach all areas of the barrel, including tight spots like the gaps between copper pipes and intricate crevices in stainless steel tanks. Additionally, due to their high temperatures and pressurized nature, wine barrel steamers are effective at killing hidden microorganisms and bacteria, ensuring a sanitary environment for fermenting and aging wine.
By adopting this innovative approach, wineries improve aromas and flavors, reaping the benefits of steam cleaning and improving the winemakers’ quality, sustainability, and reputation.
Steam vs. Ozone Treatment
Wineries prefer using dry steam over ozone for cleaning because it saves water and is better for the environment. Ozone cleaning involves converting ozone gas to liquid, which requires high water consumption. The ozone is also toxic in high concentrations, so workers require additional protection from exposure.
Dry steam, created at high temperatures without extra moisture, efficiently cleans wine barrels, tanks, and equipment without toxic chemicals. Steam sterilization helps wineries address both water conservation concerns and health and safety concerns.
Steam vs. Conventional Cleaning Agents
Using dry steam for cleaning minimizes the environmental impact of sanitization. Compared to traditional methods, steam cleaning uses very little water, avoids introducing chemicals into production, and produces wastewater that is not toxic. These benefits make steam sterilization an appealing choice for companies aiming to showcase their commitment to sustainability.
Unlike conventional cleaning agents that need time to work on surfaces, wine barrel steamers are much quicker, resulting in significantly less downtime and more efficient use of labor. Steam sterilization also helps wineries eliminate the risk of chemical residues affecting wine flavors.
