Add ABV as fermentation reading type

Edit December 2025 by Breww team: This thread was once about multiple different fermentation reading types and should really have been split at the time into multiple threads, but sadly it wasn’t.

This thread is now specifically for voting to add manual ABV logging to the fermentation readings form.

All votes on this thread now apply to adding measured ABV readings only. Thank you.

Hello,

Would it be possible to add the following fields to the ferm. reading options:

  • ABV (measured)
  • Colour (EBC)
  • Haze (EBC)

Also, we measure gravity to five decimal places but currently Breww only allows five digits total - would it be possible to add a sixth?

On a related note, would it be possible to flag vessels that are still in fermentation (and hence needing daily samples) and but then once finished fermentation and crashed, they no longer flag that they need sampling?

I hope that all makes sense - if anyone else has requests for further ferm. reading fields post them below.

Cheers

Just a progress update on some of these! Colour is now an available option to add to your batch readings form, and Breww will also allow 5 decimal places for specific gravity now.

We’ll let you know once the other two are in!

Great stuff - thanks Max!

Can we please have EBC for 2025!

Measured abv as a fermentation reading would be great for us too, as we have an Alcolyzer and don’t always rely on gravity readings

@thom-yates Apologies for missing your message before, but EBC has been an option since Max’s message in May 2021. You can enable it in Settings → Production settings → Fermentation readings form.

Hi Luke, it’s still only showing Haze as a Percentage. EBC is only available for colour.

Apologies, you’re right. It should now be an option to record Haze in EBC :tada:

Good news, this is now live in Breww :tada:

Batch readings have had a big update. Readings are recorded against the vessel they were taken in, and a set of rules decides which readings each vessel needs and how often. You can vary the frequency by vessel type, status, age or day of the week, use a different reading form depending on the vessel, and switch readings off entirely where they aren’t needed. There’s also a new Batch readings tab on the production dashboard showing what’s due, overdue or done for every filled vessel.

We’ve added a dozen new readings too, including ABV, apparent and real extract, residual sugar, free and total SO₂, malic and lactic acid, volatile acidity, YAN, cell viability and total package oxygen, along with units such as Baumé, Oechsle, Lovibond, kPa and ppm. If we still don’t have what you measure, you can now create your own custom readings and choose the unit and precision yourself.

Full details are in the announcement: Batch readings are now per vessel, on the schedule applicable to each one

Thanks for requesting this, and to everyone who voted and commented along the way.
