Wine Fermentation
FOR WINE AERATION:
Winemakers globally are discovering the efficiency and affordability of Mazzei injectors in invigorating fermentation through wine aeration.
In the macro aeration stage, fermenting grape must passes through a Mazzei injector, which seamlessly draws in and evenly disperses air throughout the juice, oxygenating the must. With no moving components, Mazzei wine pump-over injectors offer hassle-free operation, ease of cleaning, self-priming capability, and the ability to run dry without issue. Mazzei® injectors stand out for their superior mixing and contacting abilities, owing to their patented technology, precise engineering, and top-notch manufacturing standards.

BENEFITS OF MAZZEI WINE PUMP-OVER AERATION:
- Enhances color and character of the wine
- Supports yeast development and viability
- Reduces sulfide production
- Purges excess carbon dioxide from the top of the tank
- Can be used during racking or mixing
- Installed at top of fermentation tank or at pump discharge
- Easy installation and maintenance
- Can introduce fining agents and other wine additives at the suction port of the injector
- Easily coupled with metering valve to control the rate at which liquids are drawn
- Additions can be made from the cellar floor―no hauling buckets to the top of the tank
AVAILABLE MATERIALS FOR WINE PUMP-OVER INJECTORS:
Machined Stainless Steel:
Mazzei uses 316L stainless steel for its 316LSS wine pump-over injector models. 316L stainless is highly corrosion resistant and has a low carbon content, which eliminates carbon precipitation in the welding process.
Cast Stainless Steel:
Venturi injectors made of CF3M cast stainless steel are complementary products to our injectors made of 316LSS, a machined product. The cast stainless steel injector is a low-cost equivalent that still offers vintners all of the high performance and quality they expect in a Mazzei product. With tri-clamp fittings at all openings, cast 2081 and 3090 injectors can be installed and maintained easily. The cast stainless steel material resists corrosion and is easy to clean.
Natural Polyvinylidene Fluoride (Natural PVDF) :
Mazzei also manufactures a complete line of natural PVDF venturi injectors for the wine pump-over market in various sizes and corresponding suction capabilities.
