Winery and Vineyard Applications
McClain Ozone pioneered the use of ozone in the winery and vineyard industry. In 1994 John McClain began working with wineries on ozone sanitation solutions and has continued to revolutionize the wine industry with new advancements in ozone sanitation. His research, combined with others, documented the efficacy of ozone in barrels, bottling lines, tanks and many other winery and vineyard applications. With hundreds winery clients worldwide, McClain Ozone is the leader in the production of mobile and stationary ozone sanitation systems for the wine industry. With hundreds of winery clients around the world, McClain Ozone produces sanitation systems designed to meet the needs of any size winery (Client List available on request).
Ozone a Versatile Organic Sanitizer in the Winery
Sanitation plays a critical role in winemaking. Historically, wineries have used chlorine (and/or other halogen chemicals) and heat (hot water and/or steam) for sanitation, but both or these methods have drawbacks and restrictions.
The high energy cost of generating heat and the harmful byproducts associated with halogen chemicals have made their use problematic. Many winemakers have chosen to completely eliminate the use of chlorine and other halogenated compounds to avoid the formation of TCA (2,4,6-trichoroanisole) and other aromatic halogenated hydrocarbons which impact wine flavors.
Ozone has several characteristics that make it excellent for winery sanitation.
Application of Ozone in the Winery
Ozone has become a single source organic sanitizer in the winery. Its use allows the winemaker to produce a better product through the control of spoilage organisms, mold and mildew in the winery. Winery applications include the following:
Barrel Sanitation and Storage – Hundreds of wineries utilize McClain sanitatio systems and aqueous ozone protocols to eliminate and prevent the return of microbial spoilage organisms (i.e. Brettanomyces, Acetobacter, malolactic and lactobacillus, etc.) in barrels. No rinsing after the sanitation is required which reduces sanitation times and water usage.
Gaseous ozone is being utilized to maintain barrel and wooden upright health during storage eliminating the use of sulfur and sulfur dioxide. Protocols for the safe use of both aqueous and gaseous ozone in barrels and wooden uprights have been developed by McClain and are available to McClain clients.
Tank and Press Sanitation – The use of aqueous ozone in the sanitation of wood, stainless, polycarbonate and other tanks (wood, stainless, polycarbonate, etc.) and press equipment is a common application of ozone in wineries. Ozone, utilized with proper protocols and CT values provides effective and rapid sanitation of tanks and presses. In addition, when used in a tank recirculation mode, ozone can save hundreds of gallons of water during the tank sanitation process. The breakdown of ozone to oxygen does not result in tank damage as is often the case with chorine. No rinsing after the sanitation is required which reduces time and water usage. Protocols for the safe use of aqueous ozone in tanks and presses have been developed by McClain and are available to McClain clients.
Bottling Line Sanitation - Conserving water and energy and maintaining bottling line sterility are a major concern for wineries. The unique "cold sterilization" ability of ozone, combined with its non-contaminating qualities and low water use, make it an excellent alternative to steam and hot water. The expansion and contraction of bottling line components created by heat contribute to the long term stress and damage to bottling lines. The use of cold aqueous water eliminates these stresses resulting in less bottling line downtime and maintenance cost. Protocols for the safe use of aqueous ozone in bottling lines have been developed by McClain and are available to McClain clients.
Hose, Transfer Line, Valve, Barrel Bung and Pump Sanitation - Preventing the transfer of spoilage organisms in the winery is important to wine quality and a major concern of the winemaker. Aqueous ozone can be utilized to quickly sanitize all equipment which comes into wine contact eliminating the movement of unwanted microbes within the winery. Protocols for the safe use of aqueous ozone for winery equipment have been developed by McClain and are available to McClain clients.
Surface Sanitation – Sanitizing winery floors, walls, drains and other surfaces with aqueous ozone reduces microbes (fungi, yeast, and bacteria), maintains a sanitary winery, and eliminates background odors. Protocols for the safe use of aqueous ozone for surface sanitation have been developed by McClain and are available to McClain clients.
Air Sanitation and Vector Control – The use of gaseous ozone to control mold, airborne spoilage organisms and odors is a common practice in wineries. Gaseous ozone has also been shown to control fruit flies which are not only a nuisance but are also major vectors in the movement of spoilage organisms around the winery. Protocols for the safe and effective use of gaseous ozone have been developed by McClain and are available to McClain clients.
Application of Ozone in the Vineyard
Early empirical information on ozone in the vineyard has shown its ability to control mold, mildew and some pests when applied correctly. Ozone’s USDA organic listing and low environmental impact make it an alternative to the use of less environmentally friendly chemical treatments. In addition, ozone does not require a harvest wait time and can be utilized immediately prior to harvest.
