Brewing

Record brew day measurements, check off ingredients, and advance your batch to the brewing stage.

Enter brewing mode, by clicking on the BREWING tab.

Changing the status to brewing

Click the button to 'Change Status to Brewing', which will prompt you to 'Change Batch Status to Brewing'.

Clicking on 'Yes' updates the batch status and prompts you to update the 'Brew Date'; click yes to proceed with the current date. This is particularly useful if you plan your brews and have to swap batches around. Your brew dates will match the actual brew dates rather than the scheduled date.

The brewing process starts in the 'Mash Tab' and prompts you to prepare the ingredients to start brewing.

Mash preparation

Brew Controller option

There is the option to connect to Brew Controller, details can be found here, which enables you to control your Grainfather. NOTE: this is in Beta at the moment, so it may not work as expected.

The brewsheet section follows this. This gives you all the vital information about your brew, including gravities, color and volumes. It also gives you a breakdown of all your ingredients and process steps. You also have a button to take you to the Batch Recipe if you need to make any last-minute changes to your planned recipe, including things like ingredient batch/lot numbers, etc.

Brewsheet section

When all your ingredients are prepared and you are ready to start, click the Play button to start the brewing process. Brewfather will prompt you to perform each step, e.g. mash in, start boiling, add hops, etc. This will also start timers for the relevant section of the brewing process and will sound an audible notification whenever you have to do anything. See the Brew Tracker guide for full details on stages, timer controls, notifications, and multi-device sync.

There is also an edit timer button to allow you to modify the timer value on the fly should you wish to. The button to the right of this is the 'Skip to Next Step' button which jumps to the next step in the brewing process.

Brew Controller

When a brew controller device is enabled in Settings (Grainfather, SmartPID, or Brewtools), a Brew Controller section appears on the Brewing stage. This section lets you control your brewing device directly from the batch page. You can start a brew session, and if the device is connected, a live device display shows the current status. The controller section includes a show/hide toggle so you can collapse it when not in use.

Brew Sheet Toggle

The brew sheet section can be shown or hidden using a toggle in the section header. When visible, it displays all the vital brew day information including gravities, color, volumes, ingredient breakdowns, and process steps. A button to edit the Batch Recipe is available in the header for last-minute changes.

Measured Values

Under the Measured Values section, you also have a section for recording information about your relevant measurements related to the brewing process. Recording the values here allows you to keep track of your brew day and how your brew has gone. These values are used to calculate things like your mash and brewhouse efficiency, ABV, etc. You can also click the +Add button to add any extra values that you wish to record, such as first runnings, finishing sparge gravities, etc.

Measured Values section

The following measured value fields are available during the Brewing stage:

• Mash pH — The measured pH of the mash (placeholder defaults to the recipe's target mash pH or 5.4)

• First Wort Gravity — Appears when Conversion Efficiency is enabled in experimental settings and the recipe has a first wort gravity defined

• Boil Vol — The measured pre-boil volume

• Pre-Boil Gravity — The measured gravity before the boil begins

• Post-Boil Gravity — The measured gravity after the boil

• Post-Boil Kettle Vol — The measured volume remaining in the kettle after the boil

• Original Gravity (OG) — The measured original gravity of the wort going into the fermenter

• Fermenter Top-Up — Any water added to the fermenter after the boil

• Fermenter Vol — The total volume in the fermenter

These values carry forward to the Fermenting and Completed stages, so you only need to enter them once. Custom measured values can be added with the +Add button for anything else you want to track (e.g., sparge runnings, mash-out gravity).
