Grapes love our Tanks

The first wine tank manufactured in 1981 by JVNW was floating lid tank for Amity Vineyards in Amity, Oregon. It was also the first floating lid tank manufactured in the US. It is still in use today along with its more modern sisters and brothers. There have been a lot of ‘firsts’ in JVNW wine tanks. Grapes love our tanks.

 

Wine is a pleasure of the senses. JVNW wine tanks make good sense and the Engineering Department takes pleasure in pushing the boundaries of what started as simple fermentation storage units. Today, the tanks can be gentle giants featuring sophisticated monitoring systems or simple totes for the elegance of single lot fermentation.

Automated Pomace Removal Wine Tanks

Slide Bottom Cone

Non-contact emptying process

JVNW Engineers often work in a collaborative environment with winemakers. The Scheid Slide was a joint effort that solved several of the wineries most serious problems and added the following features that made this a highly successful joint venture; the results are now available to all large scale production wineries.

 

 

 

 

 

 

  • Manual pomace removal eliminated.
  • Direct pomace-to-press.
  • Economical bottom cone/inverted dish design.
  • Bottom cone cooling.
  • Cap-breaker feature, optional.
  • Motor is wash-down safe.
  • Over-sized discharge chute.
  • Non-contact sweeps automatically clear tank floor.







JVNW Combi Tanks TM

 

The JVNW Combi Tank is comprised of two tanks stacked one over the other. The top tank is an open top primary fermentation tank. The lower tank acts as storage for the fermented wine. The top tank can be used as additional storage during the off-season.

 

The Combi Tank is excellent for use in the red wine fermentation process known as delestage, or "rack and return". Gravity pulls the juice from the upper fermentation tank down to the lower, entering in over the top to become aerated. It then travels back into the upper tank and back onto the huddled mass of grape skins, thus accomplishing a second aeration. This process is efficient and simple with the JVNW Combi Tank, fewer hoses reduces cleaning, no harsh pumping action for gentle grape handling, and a faster more efficient use of time and manpower.

 

Open top, punch down fermentation tank has a sloped bottom for easy pomace out direct to press.

Options / Features

 

Whether a wine tank is conical, truncated, dished or open top; all are available in 2B (mill) finish or polished stainless steel. Specialized or standard manways are the best part of any JVNW Wine Tank and a great source of pride.

 

Dimpled heat transfer surface (HTS) allow economical cooling/heating jackets to regulate the heat of fermentation. Multiple or split jackets offer precise control.

 

Fittings, valves, rotating racking arms, vents, pump-over piping extensions, removable drain screens, or cap management mechanisms, are all tools apart of the winemakers magic.

 

Fittings are always adjusted, angled or gusseted per the winemaker's instructions. Temperature wells are always gusseted for extra strength.

 

New louvered drain screen is offered as an alternative to the standard perforated screens.

 

Tank floors have changed dramatically in the past serveral years. Although flat & sloping with sump drains, dished or conical tank bottoms are still standard; new designs of steeply truncated floors have advantages when confined entry space regulations are involved.

 

Powder coated (painted) or stainless steel Legs/Bases are adjustable and can always accommodate fork lifts. Legs can be replaced with anchor pads for bench mounted tanks. Tank sizing specifications reflect seismic conditions. Adjustable foot pads for uneven ground surface are always constructed of stainless steel material.
