Stainless Steel Wine Fermenters

Stainless steel wine fermenters are vessels used to ferment grape juice into wine. They allow precise temperature control and prevent oxidation during the fermentation process. Key features of stainless steel fermenters include:

Types of Stainless Steel Wine Fermenters

Open TopHave an open top allowing easy adding of juice/fruit and pulp
Closed TopHave a closed top with valves to add ingredients and remove samples
Variable CapacityAllow adjustment of capacity from a few gallons to over 1,000 gallons
Custom DesignFully customizable in size, shape, valves, temperature controls, etc.

Stainless Steel Wine Fermenter Sizes

Small5-60 gallons, used by home winemakers and small commercial wineries
Medium60-1,000 gallons, for medium scale production
LargeOver 1,000 gallons, used by large commercial wineries
CustomAny capacity based on winery needs

Stainless Steel Wine Fermenter Design and Layout

Stainless steel wine fermenters have an interior chamber for holding juice/wine which can have the following design elements:

  • Conical or cylindrical shape
  • Slope bottom towards center drain valve
  • Glycol/refrigeration cooling jacket
  • Insulated chamber
  • Temperature sensors
  • Sample ports
  • Pressure relief valves
  • Access hatches and doors
  • Legs and casters for mobility
  • External sight glasses to view interior level

The layout depends on the winery, with custom options for dimensions, number/size of fermenters, positioning, etc.

Customization of Stainless Steel Wine Fermenters

Stainless steel wine fermenters can be customized in terms of:

  • Capacity – from a few gallons to thousands of gallons
  • Dimension ratios – height, width, depth
  • Shape – conical, cylindrical, rectangular
  • Number and types of valves
  • Cooling system – glycol, refrigeration, chilled water
  • Temperature sensors and automated controls
  • Access hatches, doors, ladders
  • Integrated destemmers, crushers
  • Mobility options – fixed, casters, fork lift guides
  • External sight glasses, light tubes
  • Special coatings – silicone, epoxy

Q: What size/capacity stainless steel wine fermenter should I choose?

A: Choose a fermenter capacity that can hold your maximum desired batch size with room for foam/expansion. Factor in potential future production increases.

Q: Should I choose conical or cylindrical stainless wine fermenters?

A: Conical fermenters allow easier removal of sediment but cylindrical designs allow easier cleaning. Choose based on budget, sediment removal needs, and ease of cleaning.

Q: What temperature control system is best?

A: Glycol and refrigeration cooling systems provide the most precise temperature control. Evaluate options based on control needs and budget.

Q: Should I buy imported or American-made stainless wine fermenters?

A: Both can offer quality equipment. Domestic providers allow direct customer service while imports have lower prices.
