INSTANT WINERY! No infrastructure needed. No installation. No water usage. No wastewater
generation. No building permits. No expensive press to purchase, maintain and clean. Fully
automated punch – just set and forget. Estimate 2-4 manhours /batch total. Here is a quick
guide to winemaking in the GOfermentor and the equipment required. You can start your own
winery for approximately $8000. For detailed operation please consult the Operating Manual
and website www.GOfermentor.com.
Red Wine:
Filling:
Red wine is made using red grapes. The color and tannins are extracted from the skins and
seeds, and we do not recommend making red wine from juice or concentrates. Grapes can be
received in clusters or machine picked (destemmed and partially crushed).
1. Using grape clusters: Grapes are typically attached to the stems in clusters. Grapes can
be destemmed using a mechanical destemmer. An example is shown below:
Motorized destemmer/crusher with built-in grape pump. About $ 2000 from morewine.com
The destemmed grapes can be crushed using optional rollers below the destemmer or
left uncrushed altogether or in part (resulting in fruitier wine with less extraction). Next
they are loaded into the GOfermentor liner.
2. Using destemmed grapes: The destemmed grapes must be loaded into the GOfermentor
plastic bag. This is very easy if the destemmer has a built-in grape pump (such as the
one shown above). Simply connect the outlet of the grape pump to a 2 inch hose and
connect the other end to the front top port on the GOliner bag. Run the destemmer to
fill it with grapes. If the grapes are received destemmed, they can still be dumped into
the destemmer and conveyed. If a suitable destemmer with pump is not available, a
must pump capable of handling whole grapes should be used to pump the grapes into
the GOliner. Alternatively, grapes can be manually loaded by cutting an opening into the
liner and using a hopper above the GOLiner or simply transferring grapes by hand. The

Questions and answers

Summary of Contents for Go Fermentor GOfermentor

  • Page 1 – just set and forget. Estimate 2-4 manhours /batch total. Here is a quick guide to winemaking in the GOfermentor and the equipment required. You can start your own winery for approximately $8000. For detailed operation please consult the Operating Manual and website www.GOfermentor.com.
  • Page 2 Fermentation: Each GOfermentor unit consists of a controller and an outer container (GObase). Options are temperature probe/sampler (GOtemp) and cooling plate with valves (GOcooler). Minimum capacity is 200 Kg grapes (440 lbs) and maximum is 1000 Kg (metric ton = 2200 lbs), One ton of grapes will yield between 120 and 160 gallons (600- 800 bottles) of wine.
  • Page 3 For sound grapes, use a teaspoon of potassium metabisulfite (KMBS) for each 200 pounds, sprinkled in slowly at the crusher to obtain good mixing. The GOfermentor will do the rest.
  • Page 4 To press from the GOfermentor you need the optional GOpress pressing tube. Remove the VENT assembly from he GOliner and insert the GOpress tube. Fasten with the supplied special triclamp. Now connect a wine pump to the outlet of the GOpress tube using a 2-inch hose.
  • Page 5 Free SO should be maintained at 25-35 ppm. For the adventurous, good results have been obtained with GOfermentor technology without any sulfur dioxide additions. The system’s design minimizes contamination, thus greatly reducing the risk of this strategy.
  • Page 6 In this method, destemmed grapes are put into the GOfermentor liner as described in the section on red wine making. The GOpress tube and a pump is connected to the inlet on a second GOfermentor liner.
  • Page 7 Fermentation: Since there are no skins and seeds in white wine production, there is no cap to manage. The automatic punch feature is not necessary but it is very useful to program a gentle punch every day or so. This action stirs up the yeast that settles to the bottom and also provides a more uniform temperature.
  • Page 8: Required Equipment

    The GOBase outer container determines the floor space and height. The fermentation bag is placed inside the GObase container. The GObase container has a pallet base and can be moved by pallet jack or fork lift. The GOfermentor control panel mounts to the GObase. One controller is required per base. Electrical power: 110 VAC (10A).
  • Page 9: Optional Equipment

    (1/2”NPT process connections). The GOcooler requires the purchase of the GOtemp sampling/temperature probe. The GOfermentor is the most economical option for a small winery. The basic equipment is just $ 1700 per unit and requires minimal infrastructure. Operating cost is just $ 100/run for the single-use GOliner fermentation bag.
