Winemaking Equipment

Wine fermentation tanks, (or “Wine Fermenters”), are key winemaking equipment components. These specialized tanks are made of food-grade stainless steel, concrete, wood, or other non-ferrous materials. During fermentation, yeast converts the sugars found in grape juice to alcohol. Wine fermenters facilitate and control the fermentation process. Well designed wine fermenters precisely control temperature, are easily cleaned and have safety features to protect winery operators.

All of our wine fermenters include the following standard features:

  • Vitis top (for closed-top configurations only):
    • Truncated conical top: can be either offset or centered for ease of cleaning and cap punchdown operations
    • Punchdown manway: fully welded into the truncated conical top, allows easy access into the tank for punchdown, inspection, and service
    • Zero pressure/vacuum break: prevents any pressure or vacuum buildup inside of the tank

  • Vitis sidewall:
    • Interior finish: smooth 2-B interior finish, blended and made sanitary at all weldment
    • Dimple jacket: our energy-saving precision laser-welded dimple cooling jackets are hydroformed and baffled to maximize turbulence and minimize load on the glycol cooling system. Both low- and high-pressure options are available
    • Dual-action manway (round): top inswing and outswing manway for complete racking access
    • Dump-out manway (square): outswing only and located at base of sidewall allows complete cleanout of pomace and wash debris

    • Racking port
    • Temperature Thermowell port: includes protective temperature control shield
    • Sample port: includes a sidewall valve so samples can be collected easily

Portland Kettle Works designs and engineers our wine fermenters with key winemaker issues in mind:

Safety – PKW places winery workers’ safety and your success at the forefront of our design and engineering

Safety is key for any winery. Portland Kettle Works has years of safe design experience. We integrate key safety features like clean-in-place (CIP), modulating pump and transfer systems and emergency shut down. PKW uses UL listed 508A parts in every system we design, build, and ship from our Portland, Oregon USA manufacturing facility.

Sanitation – Wine safety begins with proper sanitation

All PKW tanks are designed and engineered using 304 food-grade American stainless steel to maximize sanitary features.  Both the interior and exterior of all PKW wine fermenters and tanks are fabricated, welded, and blended to reduce cleaning time and expense.

Temperature Control – The key to winemaking repeatability and consistency

PKW replaces guesswork with simple, easy to use automation features for precise temperature control.  We completely integrated these controls into our wine fermenters and tanks to make repeatability and consistency a hallmark of your brand.
