Sky Acres’ GOFermentor System of the Future

WineEnthusiast, April 3, 2019

At Sky Acres Winery in Far Hills, New Jersey, fermentation engineer Vijay Singh and his wife, winemaker Meera Singh, craft wine in an unconventional way. The semi-retired couple has patented the GOfermentor, a winemaking system that occupies a small footprint, but has delivered outsized results.

Fermenting Wine Grapes in a Bag

The GOfermentor enables quality improvement in small wineries, By Richard Carey


GOfermentor is a new method of managing fermentations of 1-ton lots of grapes. A large plastic bag with two compartments is placed in a specially designed bin. After crushing, the grapes are put in one compartment and sealed. As the second compartment is filled with air, it pushes against the grape bag, which forces juice through the cap.

A major advantage of the GOfermentor is the reduction of water use in the winery. The cellar stays clean during fermentation, and cleanup after fermentation is easy because pomace stays in the bag, which is recyclable.

The GOfermentor system gives a winemaker flexibility in managing small or odd-size lots of grapes.

The GOfermentor Improves Quality

The single-use fermentation liner is delivered clean and the fermentation is performed entirely inside this sealed environment with no exposure to air. The automated cap management punch technology gently extracts more color and flavor than any conventional system. This results in increased freshness, reduced oxidation and better quality wine.

Stops Water Wastage

90% of water usage in a winery is water wasted in washing operations. The GOfermentor uses FDA approved food-grade, biodegradable, single-use liners that eliminate most of the washing operations. No need for washing before or after use.

Saves Time and Capital

Just move the palleted container into the fermentation area, connect it to a household electric plug and put in a new liner. GOfermentor bis ready to fill in less than 20 minutes of set up. No press to clean and maintain. No installation cost. Complete systems start as low as $1500. Total hours per batch as low as 2 hours.

Reduces Labor

Washing operations are totally eliminated. At the end of fermentation, press out the wine using the integral press. Use a pump-over sump strainer to remove any entrained seeds, skins, and stems, and collect the clarified wine in another bag or other container. Then pull out the liner containing the residual pomace and disperse it as fertilizer in the vineyard. Discard the biodegradable liner. Done.


GOfermentor was created by Meera and Vijay Singh. We started winemaking for ourselves and found the existing technology too tedious and environmentally unsound. Traditional winemaking is more janitorial work than wine making! You have to wash all the tanks before you start, then you clean all the equipment, then you have to wash the whole mess again when you are done. Punchdown is another tedious and dangerous process. The overwhelming amount of work led us to rethink the whole winemaking process, to optimize it so that it could be run by just the two of us. To our surprise, the new automated punchdown technology helped us extract better color and flavor. Our wines won awards, and others wanted to use the technology. After a number of trials at various wineries in 2015 and 2016 the technology is now commercial. Buy the low-cost patented GOfermentor. Made in USA.


Dr Singh is a world-recognized biotech scientist, he developed the highly acclaimed Wave Bioreactor which revolutionized the production of biopharmaceuticals by using a disposable cultivation bag. He decided to apply his expertise in disposable processing to the key issues of winemaking. The patented GOfermentor and SmartBarrel wine aging/storage system was born out of this work.
