Why Winemakers Choose GOfermentor
Automated Punch
Unattended punch-up operation — set your schedule on the controller or your smartphone. This unique "punch-up" concept is only possible with flexible bag technology, and is the secret to GOfermentor's superior extraction of color and flavor.
Built-in Press
Insert the pressing tube and pump out the wine. The GOfermentor uses the secondary inflation chamber as a built-in bladder press. Pressing takes less than an hour — no separate press needed.
No Cleaning
Medical grade BPA-free biodegradable single-use liner. No contamination, no off-odors. Zero cross-contamination between batches — simply discard the liner when done.
No Waste Water
Water usage is reduced by 90% on average. No washing, no steaming, no detergents. Minimal waste water generation helps the environment and saves money.
No Installation
Requires only 4'x4' of floor space and standard household electric service (110 VAC, 10 amp). Plug and play — no permanent installation needed.
Temperature Control
Optional stainless steel heat exchanger plate connects to chilled water or glycol. Automatic temperature maintenance during fermentation — can also be used to heat.
Two Core Components
The GOfermentor consists of two main components: GObase and Controller. Single-use GOliners sold separately.
GObase
A reusable, rigid outer container that holds the GOliner. Since wine never contacts the GObase, it can be reused with a simple wipe down. It folds for compact storage.
Controller
Advanced instrumentation that logs data, events, and alarms. A smartphone app allows remote monitoring and control over the Internet from anywhere in the world.
Revolutionary Automated Punch-Up
The primary challenge of red wine fermentation is managing the "cap" — the solids that float to the surface from CO2. Instead of forcing the cap down, the GOfermentor pushes liquid upward by inflating a secondary chamber for superior extraction of color and flavor.
Initiate
The electric vent valve opens, venting CO2 to atmosphere and deflating the primary chamber.
Squeeze
The secondary chamber rapidly inflates via built-in fan, squeezing the primary chamber upward and forcing liquid through the cap. Pulsed pressure breaks up the cap.
Complete
The fan shuts off, secondary chamber deflates, and the electric vent closes. The primary chamber repressurizes as CO2 builds. Excess pressure is automatically vented.
Red Wine & White Wine
1 ton capacity. 150 gallons/ton yield or more. 4'x4' space. 110VAC. No installation.
Red Wine
Automated cap management for superior color and flavor extraction.
Insert GOliner into GObase. Connect destemmer/crusher via 2" Triclamp port, or fill by gravity or by hand.
Primary chamber inflates from CO2. Set automated punch schedule via controller or smartphone app. Sample anytime via fill port.
Stop punching 2 days before pressing. Insert pressing tube, pump out free-run wine, then activate PRESS to squeeze pomace. Under 1 hour with one operator.
Discard the GOliner with waste pomace. No cleaning, no steaming, no detergents — GObase gets a simple wipe down.
Built-in bladder press for red wine
White Wine
Sealed design preserves delicate aromatics with no oxidation.
Fill primary chamber with 200–1,000 lbs crushed grapes. Insert Press Tube, connect pump, direct juice into a secondary GOliner.
Activate PRESS function to extract all juice. Sealed GOliner provides minimal air contact, preserving aromatics and enabling low-sulfite wines.
Juice ferments in the secondary GOliner. Sealed bag keeps air out. Use GOcooler for lower temperatures white wines prefer. Bâtonnage via punch mechanism stirs lees.
Pump contents to SmartBarrel liners, traditional barrels, or other aging equipment. Discard the GOliner — no cleaning required.
Press first, then ferment for white wine
Advanced Instrumentation & Remote Control
The advanced instrumentation logs data, events, and alarms throughout the fermentation process. A smartphone app allows remote monitoring and control over the Internet from anywhere in the world — check temperatures, adjust punch schedules, and receive alerts without being in the winery.
A sampling tube allows samples to be withdrawn at any time without opening the fermenter. The sampling tube includes a temperature sensor for continuous monitoring.
