Pre-Brewing Assembly
We recommend that you clean your G30 and its components using the Grainfather High Performance Cleaner before use. For details, refer to the full instructions online: grainfather.com/instructions/
1. Install the Filter
Illustration shows the Filter (14) with its silicone insert (49) and cap (48) being pushed into the Filter Inlet (13) on the Boiler Body.
2. Assemble the Bottom Perforated Plate and Overflow Pipework
Take the Bottom Overflow Pipe (40) and unscrew the Overflow Nut (43). Insert the Bottom Overflow Pipe through the hole in the centre of the Bottom Perforated Plate (42) and screw the Overflow Nut to hold in place. Make sure the Silicone Bottom Perforated Plate Seal (41) is fitted around the outside of the Bottom Perforated Plate.
Install the Bottom Perforated Plate into the Inner Basket (34). This is most easily done by starting with the Bottom Perforated Plate at about a 30° angle and pushing it gently down to the bottom of the Inner Basket. Once at the bottom, gently press around the circumference of the Bottom Perforated Plate Seal until the Grain Plate sits flat at the bottom of the Inner Basket.
TIP: Wet the inside of the Inner Basket or run some grain dust around it to make installation easier.
Take the Top Overflow Pipe (39) and insert this onto the top of the Bottom Overflow Pipe so that there is about an inch of overlap. Make sure that the wire springs are oriented at the bottom end. Insert the Grain Stopper (35) onto the top of the Top Overflow Pipe. The Grain Stopper has a cap on its top end which should sit on the top edge of the Top Overflow Pipe.
Diagram illustrates assembling the Bottom Perforated Plate (42) with the Bottom Overflow Pipe (40) and Overflow Nut (43). Another diagram shows the Inner Basket (34) with the assembled bottom plate and overflow pipework being gently inserted.
3. Attach the Control Box
Image shows the Control Box (30) being attached to the G30. The temperature probe cord is routed through the handle. Plugs (Pump Plug 31, Heating Element Plug 32, Control Box Power Plug 29) are shown connecting to the underside of the Control Box. A close-up shows the Control Box interface with buttons like MENU, TEMP, PUMP, SET, HEAT, CANCEL, PROCEED.
Feed the temperature probe cord on the Control Box (30) through the handle of the G30. Fit the lugs at the back of the box into the holes on the bracket and sit the Control Box on the cradle.
Insert the Pump Plug (31), and Heating Element Plug (32) into their respectively labelled sockets on the underside of the Control Box. Insert the temperature probe from the Control Box into the Thermometer Probe Cover (11) located at the bottom of the G30. Insert the Control Box Power Plug (29) into the middle socket on the underside of the Control Box. Next, plug the other end of the Control Box Power Plug into a 220 V power outlet (refer to page 2 for information about compatible 220 V power outlets).
4. Bluetooth Connection and Control from Your Mobile Device
Illustration depicts connecting the G30 to a mobile device via Bluetooth for remote control using the Grainfather App.
At this point, you will be able to use your new G30 and complete a brew using the manual Control Box. However, the G30 has built-in Bluetooth, making it compatible with the Grainfather App where you can use your mobile device as a remote control. Once you've downloaded the app, registered and connected it to your G30, you have access to a completely connected brewing experience. Please refer to the full online instructions about how to connect your mobile device to the G30: grainfather.com/instructions/
Setting Up to Brew
NOTE: This section of the Quick Start Guide outlines the key aspects of assembly required during the brewing process. For further information on the brewing process, please refer to the full instructions online: grainfather.com/instructions/
1. Add the Mash Water
Make sure that your G30 is on a stable, flat surface before you start brewing. We recommend placing the G30 on the floor due to heavy lifting later in the brewing process. Add the volume of mash water required by your recipe - you can use the advanced calculators available on the Grainfather App.
2. Set the Mash Temperature
Using the Control Box, set the required mash temperature and press the 'Heat' button to initiate heating. Place the Tempered Glass Lid (27) on the G30 to reduce the heating time. At this stage, if your G30 is connected to the Grainfather App, you can run your brew session remotely on your mobile device.
NOTE: The clips on the side of the G30 should not be used to secure the Tempered Glass Lid. These should only be used with the distilling attachment.
3. Install the Inner Basket Components
Place the Inner Basket, complete with Bottom Perforated Plate and Overflow Pipework, inside your G30.
4. Add Grains and Stir
Once your water reaches the set temperature, add the grain to the Inner Basket, stirring well to avoid any dry clumps.
5. Install the Top Perforated Plate and Overflow Inlet
Fit the Top Perforated Plate (38) with the Top Perforated Plate Seal (37). Insert the Top Perforated Plate into the Inner Basket until it rests on top of the grain bed, making sure that the plate is level. Next, remove the Grain Stopper (35) and fit the Overflow Inlet (36) onto the Top Overflow Pipe (39), gently pressing down until it fits into the hole of the Top Perforated Plate.
6. Assemble and Attach the Recirculation Pipe
Diagram shows the Silicone Hose (26) connected to the Recirculation Pipe (25) and fed through the Tempered Glass Lid (27) to connect to the Safety Valve (23).
Insert the Silicone Hose (26) over the barbed end of the Recirculation Pipe (25). Place the Tempered Glass Lid on the G30. Feed the Silicone Hose through the hole in the Tempered Glass Lid and firmly screw the Recirculation Pipe onto the Safety Valve (23). Make sure that it is threaded on correctly and securely. The end of the Silicone Hose should rest on the Top Perforated Plate.
7. Recirculate Your Mash (Wort)
Illustration shows the pump circulating wort. A Ball Valve (21) is used to control the flow rate into the Overflow Inlet (36).
Activate the pump to recirculate your wort. Use the Ball Valve (21) to adjust the flow rate so that the wort level is just above the Overflow Inlet, allowing a small amount of wort to overflow through the Overflow Inlet. Prepare your sparge water during the mash.
8. Lifting the Inner Basket
Image shows the Inner Basket Lifting Handle (33) inserted into the Inner Basket (34). Another image shows the Inner Basket resting on the Support Ring (46) inside the Boiler Body. A diagram highlights the Support Ring Retainer.
When the mash has finished, turn off the pump and remove the Recirculation Pipe and Glass Lid. Close the Ball Valve and insert the Inner Basket Lifting Handle (33) into the two opposite holes in the Inner Basket. Lift the Inner Basket, and then turn it 45° so that the feet at the bottom rest securely on the Support Ring (46).
CAUTION!
BE VERY CAREFUL not to twist the Inner Basket while it is on the Support Ring in the sparge position as it could knock it off the Support Ring. If the sparge is "stuck" (not draining), then remove the Top Perforated Plate and slice the grain bed with a stainless steel paddle. Cut through the stuck mash from the centre towards the outside repeatedly until it starts draining. This should keep the Inner Basket safely in place on the Support Ring. Do not stir the grain bed as this could twist the Inner Basket off the Support Ring.
Always ensure the Support Ring fits tightly into its groove and is held in place by the Support Ring Retainer. If you remove the Support Ring for cleaning, ensure that it is correctly reinstalled along with the Support Ring Retainer.
Diagrams illustrate correct and incorrect placement of the Inner Basket on the Support Ring. A green checkmark ✔️ indicates correct placement, while a red cross ❌ indicates incorrect placement, showing the basket tilted or not seated properly.
9. Sparge Your Mash
Gently press the Top Perforated Plate down until it comes to rest against the grain and then sparge the mash. Once the sparge is finished, use the Inner Basket Lifting Handle to remove the Inner Basket from the G30.
10. Boil Your Wort
After removing the Inner Basket, complete the boil and add the hop additions required by your recipe.
CAUTION!
During the boil, do not fit the Glass Lid as you may cause a boilover.
11. Cooling with the Counterflow Wort Chiller
Diagram of the Counterflow Wort Chiller shows two hoses: a red hose labeled 'HOT WATER OUT' and a blue hose labeled 'COLD WATER IN'. The wort flows are indicated: 'COLD WORT OUT' and 'HOT WORT IN'.
The G30 includes a Counterflow Wort Chiller (45). This has been custom designed to efficiently cool your wort and allow easy, and sanitary transfer directly into a fermenter. At the end of the boil, circulate hot wort through the Counterflow Wort Chiller for 2 minutes to sanitise it. Then turn on your cooling water and transfer your wort through the Counterflow Wort Chiller into your cleaned and sanitised fermenter. For detailed instructions on how to use the Counterflow Wort Chiller, please see the full instructions online: grainfather.com/instructions/
12. Cleaning
At the end of your brew day, clean and dry the G30 and all its components thoroughly. We recommend using the Grainfather High Performance Cleaner, as it removes the need for tedious scrubbing. For further advice, please refer to the cleaning section of the full instructions online: grainfather.com/instructions/
