Hello, Please find, below, some detail on the potential of automated cell counting. The first version of the app is now available for testing. If you're interested in testing, please send me a message via the contact page

A sample of cells: you could count them by eye, if pressed

A fairly simple setup. Liquid-handling garb out of shot

About 1.7 billion cells/ml

Not perfect, but pretty good


CellMate is a piece of software for automated cell counting with a microscope & camera.

Whilst CellMate focuses on the effort-intensive counting exercise, it is designed to help capture & analyse the whole fermentation, from dissolved oxygen to attenuation. By doing so, the brewer, distiller or winemaker is able to analyse, improve and repeat.



Successful primary fermentation, whether it's beer, whisky or wine, achieves both production of the desired flavour profile and an efficient and reliable attenuation, leaving us with the desired product and ready for the next fermentation. In the case of secondary fermentation, we're looking to create the desired level of carbonation, but also aiming to fine-tune or retain our flavour profile.

In either case, to hit our targets accurately and consistently, we need to pay close attention to our yeast. Changes in inputs (ie. pitch rate, dissolved oxygen, amino acids) or conditions (ie. temperature) will affect comings and goings of chemical pathways within each cell. This very simplified diagram shows some of our key concerns.

Just for example, if we pitch too few yeast cells, they're likely to run out of steam, leaving an incomplete fermentation. Any remaining fermentable sugars are vulnerable to infection and foreign yeast strains; not to mention the missing alcohol. On the other hand, if we pitch too many cells, our yeast will compete for too few resources and are liable to produce unintended flavours and finish in poor condition for re-pitching.



The process begins as normal with sample preparation and positioning under the microscope.

A short video is probably more instructive. I'll come back to you with that shortly.

How much?

Don't worry about it for the minute. There's no cost for the application at this stage.

We'll work something out later; most likely, some time in 2019.



Soon. It's still in development. I am looking for volunteers to test the application and help work it into a finished product.


For who: This project was inspired by brewers. The product is intended to be less "weird science" and rather as simple as possible. But, of course, I am open to all types of users and happy to discuss varying needs.

Regarding myself: I'm a humble yeast enthusiast with similar enthusiasm for beer, wine, gin; and the rest


Great. I'd love to hear expressions of interest. Give me a shout on or via the Contact page

As I mentioned, I will be making a limited initial release available to those who can assist with testing.
