Logging your fermentation in the Analysis tab

Once you have brewed a batch, you can log your fermentation readings. You can log these readings in the Analysis tab on a batch. If you have selected Copy reading to fermentation logs on a recipe gravity reading, this will automatically add your OG reading to your fermentation logs when completed in the brewing page.

Add a fermentation reading

You can add a reading whilst on the batch by navigating to the analysis tab and selecting Screenshot 2023-10-27 at 15.02.45. You can also quickly add a reading on the main production dashboard by selecting the vessel holding your batch and selecting image, as in the screenshot below.


You can then log a time, gravity reading, vessel temperature and pH. You can also select a Gravity reading type of either Orginal or Final gravity. If your reading is being taken whilst tracking your fermentation, you can just leave this blank.

By selecting Production settings, you can also choose other reading categories to display, such as CO₂ and if and which of them are mandatory when completing a reading.

If you have taken both a gravity reading marked as Original gravity and a gravity reading marked as Final Gravity, then Breww will also add a calculated ABV to your batch, and you can choose in your Beer duty settings or on an individual batch which ABV to use for duty purposes from advertised, calculated or manually entered/custom specified.

Fermentation graphs

As you log your fermentation readings, this data will automatically get plotted onto a Fermentation summary graph and Yeast attenuation graph.

The above examples are readings taken from a batch that was brewed on a Breww team brew day using the Tilt hydrometer integration, logging the fermentation data over a period of time and automatically plotting the fermentation graphs!

You can find out more about fermentation monitoring integrations by heading to IntegrationsFermentation monitoring in your Breww account.
