Wine Making Equipment

Wine fermentation tanks, or wine fermenters, are key components in winemaking. Wine fermenters are specialized tanks made of food-grade stainless steel, concrete, wood, or other non-ferrous materials. Wine fermenters are specifically designed to facilitate and control the wine fermentation process wherein yeast converts the sugars found in grape juice to alcohol.   Well-designed wine fermenters precisely control temperature, are easily cleaned, and are engineered with safety features that eliminate hazards to winery operators.

    • Punchdown manway: fully welded into the truncated conical top, allows for 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

    • 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

PKW’s Vitis Wine Fermenters are designed and engineered with the winemaker in mind.  We have thought through:

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

Safety is a key component of any winery tank farm. Over generations of design, PKW has seamlessly integrated safety features like clean-in-place (CIP) facilities, modulating pump and transfer systems, emergency shut down systems, and UL listed 508A componentry into every system we design, build, and ship from our American manufacturing facility located in Portland Oregon.

Sanitation – Wine safety begins with proper sanitation

All PKW tanks feature 304 food-grade American stainless steel designed and engineered 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 that assure precise temperature control.  This control is completely integrated into our wine fermenters and tanks making repeatability and consistency a hallmark of your brand.
