Plaato Airlock measures the Co2 produced during the fermentation and uses that to estimate the Specific Gravity. You can read more about the science behind the Plaato Airlock here.

Plaato Airlock can be used on all types of Fermentations, including: Wine, Cider, Kombucha, Whisky, Brandy, Mead, Moonshine.

The operational batch size for Plaato Airlock is 1 - 13 US gallons/ 2 - 50L.

Plaato Airlock is designed for a typical home-brewer fermenter capacity of around 6.5 US gallons/ 25 L. It will work best for these capacities.

Some brewers have tried using the Airlock on batches of around 16 US gallons / 60L with good results. It is a practical matter of how much CO2 can go through the airlock. If you ferment at low temperatures, the fermentation activity will be lower and the Airlock can work well on bigger batches.

Yes! Plaato Airock will work in your fridge until your beer freezes.

Then it will stop working.

Plaato Airlock measures the ambient temperature. That is the air temperature around the Airlock. It measures in Degree Celsius and Fahrenheit

Plaato airlock is generally designed to withstand overflow. Some overflows might be more violent than others, so depending on each and every situation, the data and device might be affected. If you notice a significant change in the graph, it is probably an indication that your beer is overflowing. In that case, clean the airlock, sanitise and put it back on.

You can open your fermenter and dry hop as normal. The little amount of CO2 that escapes when the lid is off only affects the measurements marginally. In addition, since dry-hopping normally is done during secondary fermentation, the remaining Co2 to be produced by the wort will be low.

We know that not all the fermenters available on the market are always perfectly airtight. During the development of Plaato, we have been through 20+ different types of fermenters, and the average leak affects marginally.

Plaato Airlock will still measure the fermentation activity, gather and analyze data of your fermentation. In case of a major leak, the specific values will, of course, be off.

In this case, it might be best to invest in a new fermenter to avoid contamination.

No, Plaato Airlock is not designed to handle pressurised fermentations.

The Alcohol by volume (ABV) is estimated based on the Co2 measurements, the Original Gravity values entered and the Specific of Final Gravity at the end of the batch. You can read more about the science behind the Plaato Airlock here.

The Plaato Airlock only measures fermentation in SG for now.

You need to add liquid to your Plaato Airlock in order for the IR-sensor to be able to detect the escaping Co2 as bubbles. You can add distilled water.

We recommend using plain water only.

We recommend filling your Airlock up to the line marked on the Bubbler

Yes, Plaato Airlock is not battery powered and so it has to be plugged into power at all times. Please make sure it is powered by a 5V and 1.5Amps power head.

Plaato Airlock user's that have done this have had issues with their device.

We recommend that your Airlock be plugged directly to power.
