UT Series Automatic Pump-Over Fermentor

A pump-over Fermenter is designed to control the maceration process to optimize extracting all the grape has to offer.

The UT series Fermentors are a great choice to help in bring out of a grape all it has to offer.

Key Benefits

  • Total Control of fermentation environment
    • Sanitation
    • Limited exposure to bacteria, viruses and other contaminants
    • Controlled pump over timing and duration for maximum extraction
    • Must temperature control
    • Micro-oxidation control
    • Lower workman’s comp liability due to lifting heavy hoses or punch down tools, using ladders to do said work and exposure to large volumes of CO2.
  • Fermentors built to customers specifications
  • Built of the highest quality materials and workmanship
  • All welds are ground smooth to insure sanitation
  • Only the highest quality man-ways, valves and controls are used

Results we have seen at the Occasio Winery:

  • Increased polymeric pigments
  • Complex flavors and aromas
  • Richer, supple and integrated tannin structure
  • Reduced monometric anthocyanins
  • No cooked flavors from overripe grapes with raisins

"We have found a profound difference in structure, bouquet, color; tannins and taste resulting in a finished product superior to that of the same grapes fermented by traditional methods in micro-bins or open top tanks."
