Winery Equipment Testimonial:

"Upgrading your winery from 1000 cases per year to 3000 to 5000 can be a daunting task. The choices in winery equipment, capacity and price vary all over the place.  The great thing about Ryan is, having been a wine maker for years, he knows how to design things from start to finish. When I harvested my first ten tons of the year at 6:30 a.m., Ryan and his staff were there making sure everything was working correctly. I knew I had made a good decision."

Hoby 6 Press

Benefits of Central Inflating Membranes vs Traditional Bladder Presses


  • Higher Quality Yields
  • Higher Yields
  • Less Heavy Tannins
  • Faster Pressing Cycles
  • Less Oxidation, Less Browning on Whites
  • No Load Minimums

Having a Thinner Cake Leads to Several Advantages

New Technology Dhea Presses

  • Higher Yields at Much Lower Pressures
  • Higher Quality Yields
  • Less Heavy Tannins
  • Faster Pressing Cycles
  • Less Oxidation, Less Browning on Whites
  • Inert Gas Injection into the Drum
  • No Load Minimums
  • Bladder can reach the entire circumference of the Drum 
  • Even Pressures throughout the Press
  • 10 to 20 years Lifespan on the Bladder (5/16" Thick)
  • Lower Energy Consumption
  • Ability to Press Crushed Apples and Deshelled Pomegrantes



Old Technology Bladder Presses

Horizontal Nylon Bladder Presses


  • Lower Yields at Higher Pressures
  • Indroduction of Heavy Tannins from the skins due to high pressures needed to achieve yields 
  • Longer Pressing Cycles
  • More Lees and Fining due to having to break the Cake Multiple Times
  • More Oxidation, More Browning on Whites due to longer Pressing Cycles
  • Minimum Load Capacities for Press use and Press Efficiency
  • Thin Nylon Bladder, easier to tear and needs to be replaced more frequently (less than 1/16" thick
