Instant Winery

The GOfermentor is a patented completely automated wine making device that conducts fermentation inside bags. The GOfermentor’s  single-use system not only eliminates punch-down labor and water consumption during fermentation, but also presses the wine for you at the press of a button.  There is no washing as the bags are delivered clean, and only used once. Water usage is vastly reduced (by 90% on average), making the winery more environmentally sound. No washing, no steaming, no detergents, and minimal waste water generation. Eliminating cleaning reduces labor so the winemaker can devote their time to more productive activities.

Numerous side by side trials have shown that the GOfermentor is capable of producing superb wine with no off-odors or reductive characteristics. The GOfermentor can be programmed to perform gentle mixing on a frequent basis day and night.  The GOfermentor periodically squeezes the fermenting must in red wine using the patented internal inflatable chamber, eliminating the cap. This promotes bulk mixing unlike anything possible with pump-over or manual punching. This action also lifts the settled yeast off the bottom and disperses it. This avoids the development of stagnant layers of decomposing yeast. The temperatures can be automatically controlled using a cooling plate. As the fermentation temperatures and other parameters are more homogenous they provide more stable conditions.

The GOfermentor single-use system not only eliminates punch-down labor and water consumption during fermentation, but it also presses the wine for you at the press of a button. The system’s innately gentle  press is built into each GOfermentor, the pressure and well-engineered filtration system ensure that excellent yields, 150 gallons/ton, are obtained with the richest, softest tannins possible. This again eliminates the need to wash a conventional press. Saving water and cleaning.

After pressing, waste pomace is contained inside the fermentation bag which is then removed; the pomace can be used for compost, and the biodegradable bag is discarded. Put in a new bag and you are ready for the next fermentation.

In short, the GOfermentor enables a winery to operate with minimal water. The GOfermentor is low cost and can be installed in hours without requiring any significant infrastructure. The GOfermentor uses up to 1 ton of grapes per run. The GOfermentor used 44″x 44″ of floor space. Standard household-type electric service 110 VAC 5amp. There is no installation required, it can be folded up and stored when the winemaking season is over.

“GOfermentor is revolutionizing the wine making industry, as it requires considerably less capital and can be folded away when the winemaking is over, making it an “Instant Winery”.

Guide to GOfermentor Specifications


GOfermentor US patent 9,260,682. Foreign patents pending.


Consists of a reusable outer container with control panel – This rigid plastic container holds the fermentation liner in position. Since the wine does not contact the outer container, it can be reused between batches by simply wiping down the surfaces. A control panel with electrical components, inflation blower, and valves attaches to the rigid container for the control of punch operations, temperature, and other functions.


Single-use Fermentation liner – The fermentation is conducted entirely inside a flexible plastic liner. This liner has 2 chambers – a primary chamber where the fermenting must is contained, and a secondary chamber that can be inflated to squeeze the primary chamber. The two chambers share a common wall, but it is very important to note that the air used to inflate the secondary chamber does in no way come in contact with the fermenting must in the primary chamber. The GOliner is supplied clean and ready for use. It is intended for only one use.

GOfermentor Responsible Plastics

GOliner bags are as environmentally responsible as we know how to make them. GOfermentors eliminate nearly all wash water and associated labor.  A ton of grapes uses one GOliner 10-lb. fermentation bag.  Pomace is readily transported for use as compost or animal feed.All plastics are not alike. The leftover GOliner bag has no plasticizers or UV blockers and rapidly disintegrates in a solid waste landfill. You may find a used syringe, plastic water bottle or Styrofoam cup floating up on the beach, but you will never see an intact GOliner bag.Plastics are necessary in many applications – among them medical, sanitary, food preservation, and waste disposal. We all consume and generate waste. We cannot have a zero waste footprint. All we can do is minimize our overall impact. Read More about Responsible Plastic

Zero Footprint Winery

Wineries have a peculiarity in that they make wine only a few weeks of the year. The grapes come in, and the fermentations are run. Then the wine goes off to aging tanks and barrels and the expensive stainless-steel fermentors sit idle for the next 10 months. With the GOfermentor, you just unfold the rigid GObase containers. Order some GOliners and you are ready to ferment. When you are done, fold up and put away the GObases and control panels. Your valuable winery space is freed up. The GOfermentor enables the winery to only exists when you need it, and best of all thanks to the no-cleaning “waterless” design it has almost no environmental footprint or infrastructure.
