GOfermentor

GObase

Reusable outer container with control panel – This rigid plastic container holds the fermentation liner in position. The container can be moved by pallet jack or forklift. It is also DOT certified for truck shipment. Since the wine does not contact the outer container, it can be reused between batches by simply wiping down the surfaces. The container also folds down for storage when not in use. A panel with electrical components, inflation fan, and valves attaches to the rigid container for automatic control of punch, temperature, and other functions.

 

GOliner

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 is solely used for inflation. The two chambers share a common wall, but it is very important to note that the air used to inflate the second 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.

The GOfermentor is designed to be portable, and there is essentially no installation other than placing the unit in position and connecting to a standard electrical receptacle.

Set Up

Setting up the GOfermentor for winemaking is very easy and should take less than 15 minutes.
First set up the rigid GObase unit. Then install the single-use GOliner.

Control Panel Assembly Instructions

The control panel is shipped with a support rail and a hose support pole. Minimal assembly is required.

  1. Unscrew the three large screws on the back of the control panel
  2. Place the support rail against the control with the countersunk holes facing out.
  3. Reattach the 3 screws fastening the support rail to the control panel.
  4.  The control panel is now assembled and ready to be attached to the GOBASE.

GoBase

  1. Set the GOBASE in a suitable area. Open the folded sides and push them until they lock in place.
  2. Check that there is no debris inside the GOBASE that might damage the GOLINER.
  3. Hang the control panel on the front of the GOBASE. Let the control panel hang against the GOBASE.
  4. Loosen the wing nuts on the clamps on the left side of the control panel.
  5. Insert the longer hose support pole so that it is positioned about 12 inches above the control panel. Insert the elbow on the horizontal support pole to form an L and secure.
  6. Hand tighten the wing nuts to secure the hose support pole from sliding.

GoLiner

  1. Remove the GOLINER carefully from its packaging.
  2. Place the GOLINER inside the GOBASE. The GOLINER has 4 ports:
    • FILL PORT: This port is used to fill the GOLINER. (should face up and be positioned towards the front)
    • VENT PORT: This port is used to vent the GOLINER.
    • DRAIN PORT: This port has an integral valve and locking collar. It will be installed in the bottom opening on the front of the GOBASE.
    • INFLATION PORT: This port is used to inflate the secondary chamber of the GOLINER. It is located in the blue section of the GOLINER and marked AIR ONLY. It should face towards the rear (away from the GOBASE bottom discharge port).
  3. Reach inside the GOBASE bottom opening and pull the DRAIN PORT towards you. Pull until the tabs on either side of the DRAIN port lock into the corresponding ribs on the GOBASE.
  4. Pull up on the INFLATION PORT and secure it with the supplied bungee cord so that is it draped against the rear wall on the GOBASE – it will not be possible to reposition it once the GOLINER is full.
  5. DO NOT remove the red cap from the DRAIN PORT. You should only screw on the DN502TC TriClamp adaptor when you are ready to harvest using a 2” TriClamp hose..
  6. You have completed the GOLINER installation and are ready to fill it with crushed grapes. The next operations are different depending on if you are making red wine or white wine.

Optional GOcooler heat exchanger plate

For temperature control, the optional GOcooler heat exchanger plate is necessary.

Assemble the coolant pipes on to the heat exchanger plate (Manual – Appendix A5).

  1. Place the GOcooler on the bottom of the GObase with the vertical coolant lines at the back (opposite side to the control panel). The GOliner will be placed direct on top of the heat exchanger plate.
  2. Connect a coolant inlet hose (user-supplied) to the control valve (½” NPT) and the coolant return hose (also user-supplied) to the outlet fitting (also ½” NPT).

Red Wine

Filling

  1. Connect a destemmer/crusher to the FILL (top) port of the GOliner. Use a hose with a 2inch TriClamp fitting.
  2. Run the destemmer/crusher and use its internal pump to transfer the required amount of crushed grapes into the GOliner (max 1 ton).
  3. Disconnect the fill hose and cap the fill port.

Connections

  1. Connect the VENT valve to the VENT port using the supplied 2″Triclamp. Plug the VENT valve cable to the jack on the control panel marked VENT. Use the bungee cord to suspend the VENT valve from the eyebolt on the support pole.
  2. Connect the inflation hose using a 2″Triclamp to the BLUE port (labelled AIR ONLY)on the inflation chamber. The other end has quick-connect which should be attached to the air outlet on the control panel.

rwconnect

Temperature probe (optional)

  1. If the optional GOtemp temperature probe is to be utilized then remove the cap from the fill port and insert the GOtemp fitting. Push the end in so that it is fully immersed in the must. Secure with the 2″ Triclamp.
  2. Connect the temperature probe wire to the jack located on the top of the control panel.
  3. Power up the control panel and verify that it is operational and that temperature is displayed.

Temperature Monitoring

Temperature is monitored continuously by a probe positioned in the center and about 8 inches from the bottom. This is typically the hottest point in the fermentor. Temperature can be displayed in either degrees C or F. The temperature sensor is used control temperature by regulating flow of coolant through the optional GOcooler heat exchanger plate.

head2c sampler

Sampling (requires optional GOtemp dip tube)

Sampling is performed by connecting the supplied sampling syringe. Push the quick-connect coupler on the tubing attached to the syringe onto the mating socket on the sampling tube. This will open the flow path. Now pump the syringe to draw he sample into the collection tube. Remove the collection tube and then disconnect the sampler by pressing the release button on the mating socket. The mating socket has an internal valve that automatically shuts off when it is not connected.

sampling

Must Adjustment

  1. Samples of the must may be taken from the TOP port and any additions can be made by opening the TriClamp and lifting up the sampling tube. The sampling tube can also be removed to facilitate additions using a funnel if necessary.
  2. Inoculation with yeast is also done through the TOP port.

Initial Oxygenation

  1. Usually sufficient oxygen is introduced during the fill, but additional oxygen can be added to the must in order to get vigorous yeast growth after inoculation.
  2. This can be done by connecting a tube (with connection adaptor) to the sampler fitting and blowing air into the fermentor. In this manner, the air is introduced near the bottom ensuring efficient oxygenation.

Punch Operation

Punch of the cap may be initiated at any time in the fermentation. It can also be performed after initial must adjustment to mix all the additions and to disperse the yeast if desired.

Wine vessel fig. 1

 

To perform the punch operation using the BASIC controller:

  1. Press the PUNCH button to initiate the punch cycle.
  2. The PUNCH button will start flashing indicating that a punch is now in progress. You can press the flashing PUNCH button at any time to instantly cancel the punch.
  3. The controller will open the VENT to exhaust the fermentation chamber to the atmosphere and it will start to deflate. After about 30 seconds the blower will come on and the secondary chamber will inflate squeezing the fermentation chamber. This forces the liquid in the fermentation chamber up and also squeezes the cap. At a preset pressure, the blower will turn off and the secondary chamber will deflate. After 10 seconds or so the blower will come on again and this cycle will repeat for the preset punch time (typically 1 minute).
  4. The system will then reset, and the VENT valve will close and the fermentation chamber will slowly reinflate with the CO2 generated by the fermentation.

The punch process is exactly the same when using the PRO controller, except that the PUNCH is initiated by pressing a graphic button on the touch panel. Pressing this graphic button once the punch is underway will cancel the operation as described for the BASIC controller.

Punch to be done automatically on a user-set schedule. Timing and duration of the punch cycle can also be adjusted. The punch duration should be long enough so that the headspace is completely deflated after the punch cycle.The PRO also records all punch cycles on its event log so that a complete history of the run is maintained. Details on how to change these parameters are provided in Appendix A4.

NOTE: You may need to adjust the PUNCH pressure set-point depending on the must volume (SETUP->PUNCH). For small volumes 15”H2O is good, while for a large volume (> 600Kg) you should use a higher pressure (20”H2O) to get an effective punch.

Pressing

The GOfermentor punch system can be used to gently press out the wine at harvest. Use of the feature eliminates the need for an external press and performs the pressing operation without any damaging exposure to air. It is recommended the punching be discontinued several days prior to the anticipated harvest. At this late stage in the fermentation most of the desired components and color should have already been extracted from the cap and further punching is not useful. More importantly, discontinuing punching allows the cap to flocculate upwards and clear wine collect below it. This increases the free-run and makes pressing faster.

Wine vessel fig. 1

 

  1. Screw the supplied DN502TC adaptor to the GOliner bottom outlet valve. USE A WRENCH TO TIGHTEN. Connect this adaptor to a must pump using a 2inch TriClamp crush-proof reinforced hose rated for vacuum. Connect the outlet of the must pump to that the flow goes on a pump-over sump or similar strainer.
  2. Connect the outlet of the pump-over sump to a collection liner, tank, or barrel using another pump. The pressed wine will be collected in this container for post-fermentation operations.
  3. Now open the GOliner DRAIN valve by pushing the integral valve handle all the way to the right. Open all valves through the pump all the way to the collection vessel. You should immediately see a flow of free-run wine.
  4. Start the must pump to increase the flow, however avoid pumping too fast as this will draw in the cap. Manually keep the pump-over sump clean.
  5. Once the free run flow stops you can start to press out the liquid in the cap. At this stage initiate the press operation (MENU->PRESS CONTROL screen) to squeeze the cap gently to press out the wine. The press operation can be done several times during the pressing to get as much wine as possible out of the cap.
  6. When it evident that no more wine can be pressed out, the pressing is stopped. Close the GOliner DRAIN valve by pushing the handle all the way to the left. Disconnect the must pump.

 

Disposal

At the end of pressing a tight mass of skins and seeds will remain in the GOliner. Using a suitable device, lift  the GOliner out of the GObase. The GOliner may be taken to the vineyard and slit open to disperse the pomace as fertilizer. The empty GOliner is then simply folded up and discarded as household waste. There are no toxic chemicals in the used GOliner and it will rapidly biodegrade in a landfill. The GObase never contacts the must so it can simply be wiped down and setup with a new GOliner for the next fermentation.

White Wine

Filling

  1. Connect a destemmer/crusher to the FILL (top) port of the GOliner. Use a hose with a 2inch TriClamp fitting.
  2. Run the destemmer/crusher and use its internal pump to transfer the required amount of crushed grapes into the GOliner (max 1 ton).
  3. Disconnect the fill hose.

 

Pressing

The GOfermentor punch system can be used to gently press out the grape juice free of skins and stems. Use of the feature eliminates the need for an external press and performs a very gentle pressing operation without any damaging exposure to air.

White wine pressing-17

 

  1. Connect the BOTTOM DRAIN port of the first GOliner to the inlet of a must pump using the supplied DN502TC 2inch TriClamp adaptor. Use a crush-proof reinforced hose rated for vacuum.
  2. Connect the outlet of the must pump to feed a pump-over sump or similar strainer. Connect a hose from the outlet of the pump-over sump and use another pump to feed the grape juice into the second GOliner.  The pressed grape juice will be collected and then fermented in this second GOliner.
  3. Now open the GOliner DRAIN valve by pushing the integral valve handle all the way to the right. Open all valves through the pump all the way to the second GOliner.
  4. Start the must pump to transfer the grape juice. Press the PRESS button (PRESS CONTROL screen) periodically to press the juice out of the mass of skins, seeds, and juice in the GOliner.
  5. Manually remove seeds and skins from the pump-over sump to keep it from clogging.
  6. When it evident that no more juice can be pressed out, the pressing is stopped. Close the GOliner DRAIN valve by pushing the handle all the way to the left. Disconnect the must pump.
  7. Discard the first GOliner. The skins and seeds can be dispersed as fertilizer.
  8. Prepare the second GOliner for fermentation by connecting the vent and inflation lines (if batonage is desired). Insert the optional temperature probe/sampling tube as described earlier for red wine production.

Adjustment and Fermentation

Adjust the must by additions through the FILL port. Add yeast and perform the fermentation.

Cooling and Sampling

For white wine it is highly recommended to use the optional GO temp temperature probe and GOcooler heat exchanger plate. Temperature is monitored continuously by a probe positioned in the center and about 8 inches from the bottom. This is typically the hottest point in the fermentor.

Sampling is done as described earlier for red wine.

Batonage

The GOfermentor makes it easy to stir up the lees during fermentation and aging. The punch operation used in red wine production is used to perform the batonage. Simply press the PUNCH button and the primary fermentation chamber will be compressed and pushed upwards effectively dispersing the settled yeast.

Harvest

Connect the BOTTOM port to the inlet of a must pump using the DN502TC 2inch TriClamp adaptor. Use a crush-proof reinforced hose rated for vacuum. Connect the outlet of the must pump to a collection liner, tank, or barrel for post-fermentation operations.

Disposal

At the end of pressing a tight mass of skins and seeds will remain in the GOliner. Using a suitable device, lift  the GOliner out of the GObase. The GOliner may be taken to the vineyard and slit open to disperse the pomace as fertilizer. The empty GOliner is then simply folded up and discarded as household waste. There are no toxic chemicals in the used GOliner and it will rapidly biodegrade in a landfill. The GObase never contacts the must so it can simply be wiped down and setup with a new GOliner for the next fermentation.

FAQs

The bottom discharge port is located on the front of the GOBase

Check that all valves are open. Try running the must pump in reverse to remove any cloggage in the DRAIN port

The inflation bag has a limit of 20 inch H2O gage. The control panel will not let you set a higher pressure. An internal pressure sensor monitors pressure.

You have to use a reinforced hose rated for vacuum operation.

No. Reusing the GOliner negates the benefits of eliminating cleaning and contamination.Imagine reusing a used household garbage bag !
