Overview#

Self Hosted Cloud Hosted

BrewGraph helps you follow your beer from fermentation through conditioning and serving. It brings readings from your brewing devices into one clear view, so you can understand what is happening now and decide what to do next.

Instead of checking several apps, you can see a batch’s gravity, the temperature sent with it, notes, and progress together with the keg or bottles it becomes. Self Hosted also shows pressure and pour readings.

For live monitoring, a connected sensor sends readings to BrewGraph. The Cloud Hosted beta supports gravity readings with accompanying temperature. Self Hosted also supports pressure and weight or volume for pours. Those readings turn the physical state of a fermenter, keg, or tap into information you can use in BrewGraph.

What BrewGraph helps you do#

  • Know how fermentation is progressing. See live gravity and temperature, estimate how much sugar has fermented (attenuation) and alcohol by volume (ABV). Completion prediction is coming soon to Cloud Hosted.

  • Time brewing decisions to the beer. Use the gravity trend to judge when to dry hop, raise or lower temperature, package, or simply check back later.

  • Keep track after fermentation. Follow conditioning, what is on tap, and what is ready to serve. Keg pressure and pours are coming soon to Cloud Hosted.

  • Know your beer inventory. Track what you have in kegs and bottles. Pour-based remaining volume is coming soon to Cloud Hosted.

  • Catch problems early. See battery information where a device provides it. Missed-reading and battery-trend warnings are available on Self Hosted and coming soon to Cloud Hosted.

  • Keep a useful record. Store batch details, yeast, notes, readings, and exports in one place rather than trying to reconstruct a brew day later.

  • Brew more consistently. Keep gravity, temperature, timing, and notes for later review. Cross-batch comparison is coming soon to Cloud Hosted.

Why it stands out#

Most brewing tools focus on recipes, a single sensor, or just fermentation. BrewGraph focuses on the whole cold side of brewing: fermentation, storage, and serving. A gravity reading is not isolated from the batch it belongs to, and a keg is not forgotten once fermentation ends.

BrewGraph is a complement to recipe tools such as Brewfather and Brewer’s Friend, not a replacement for them. Use those tools to plan recipes and brew days; bring the batch into BrewGraph to follow what happens once fermentation starts. BrewGraph can import batch information from Brewfather, keeping your existing recipe workflow intact.

It works with both DIY devices and compatible commercial devices, rather than requiring one proprietary sensor ecosystem. You choose the setup that suits your brewing: build it yourself, use a commercial device, or combine both. Cloud Hosted currently accepts the supported gravity devices; standalone temperature, pressure, and pour devices are coming soon.

The aim is to support as many useful devices as possible as BrewGraph evolves. At launch, support is focused on the project’s own open-source devices, with additional DIY and commercial integrations added over time where they are a good fit for brewers.

Finally, BrewGraph is available in two ways: run Self Hosted on your own equipment for full control of your data, or choose Cloud Hosted when you want the convenience of a managed service. The brewing workflow stays familiar either way, but the two options will not necessarily have identical features. Each feature is included where it can be implemented reliably and usefully in that environment. See Choose your BrewGraph to choose an edition, then Launch features for the current launch availability.

The core concepts#

Concept

What it means

Device

A sensor or monitor that sends information such as gravity, temperature, pressure, or pours.

Batch

One brew in progress. It holds the beer’s details, readings, notes, and fermentation progress.

Reading

A measurement from a device, such as a gravity or temperature value. Readings build the charts you use to understand a batch.

Fermentation step

A temperature stage such as primary fermentation or cold crashing. Available on Self Hosted; coming soon to Cloud Hosted.

Storage vessel

A keg, bottle batch, or other container used after packaging.

Tap

A serving position linked to a keg. The Cloud Hosted beta shows what is on tap; pour tracking is coming soon.

The brewing workflow, start to finish#

1. Ferment & track

Connect a gravity device and watch gravity, accompanying temperature, and notes update as fermentation progresses. Pressure is available on Self Hosted and coming soon to Cloud Hosted.

2. Package & condition

Move the batch into a storage vessel — keg or bottles — and follow conditioning until it is ready.

3. Serve from tap or bottle

Link a keg vessel to a tap and see what is serving. Pour tracking is available on Self Hosted and coming soon to Cloud Hosted.

How a typical brew flows through BrewGraph#

  1. Create or import a batch and add the details you care about.

  2. Connect a device and assign it to that batch.

  3. Follow the live readings and fermentation progress as the beer changes.

  4. Add notes and use the gravity trend to time steps such as dry hopping, temperature changes, and packaging.

  5. Package into a storage vessel, then link it to a tap when it is ready to serve.
