Your brewery on an e-ink display.
The BrewForge plugin for TRMNL shows a fermenting batch or your beer stock on a quiet e-ink screen next to the fermenter or the kegerator.
Fermentation tracking screen
Pick a batch in the Fermenting state and the screen shows where it stands, without opening a laptop in the cellar.
- Current gravity and temperature
- Progress toward final gravity
- Recent gravity and temperature trend
- When the data was last updated
Beer stock screen
See what is left in the cellar at a glance, with the beers that are running low first.
- Active finished beer stock by batch or beer name
- Low-stock beers first, total beer left on top
- Amounts as short text or as container icons on the full screen
Fits every TRMNL layout
Both screens come in full, half horizontal, half vertical and quadrant layouts, so BrewForge can share the display with your other TRMNL plugins in a mashup.

TRMNL questions
Do I have to copy an API token into TRMNL?
No. You install the BrewForge plugin from TRMNL and sign in to BrewForge when prompted. TRMNL's install flow connects the plugin to your account.
Can I show fermentation and beer stock at the same time?
Yes. Each installed plugin shows one screen. Install the BrewForge plugin more than once to get several playlist items, for example one fermentation screen and one beer stock screen.
How often does the display update?
TRMNL fetches the screen from BrewForge on its normal playlist schedule. To change what is shown, open the plugin settings in BrewForge and pick another screen or fermenting batch.
Which plan includes TRMNL?
The TRMNL plugin is part of Pro ($29.99/year). Pro comes with a 1 month free trial.
