Ampha X10 measuring brewing yeast viability on the brewery floor

On-site yeast analysis for breweries

Your pitch, measured — on the floor, in a minute

The pitch decides the batch — yet slurry weight and a slow lab result can't tell you what's actually alive. Single-cell yeast analysis gives you the real numbers — viable cells, how many are in active growth, and the exact amount to pitch — right on the brewery floor, with the Ampha X10.

Built for breweries — fast, on-the-floor yeast measurement for any brewing Saccharomyces, ales and lagers. Most valuable if you repitch yeast, run more than one site, or fight batch-to-batch consistency — without the overhead of a lab bench or a tank-integrated skid.

The payoff

Brew faster without compromising on quality

Pitching the right amount every time means faster, more predictable fermentation — so tanks free up sooner and the same brewhouse turns out more beer.

What faster fermentation could pay back

A cleaner, more consistent pitch shortens fermentation — so the same brewhouse fits more batches. Enter your own numbers to see the payback.

Based on about 8 more batches a year (~€40'000 extra margin), from ~10% faster fermentation.

Assumes fermentation normally takes 5 days, about 10% faster with a measured pitch (typically 10–20%), and 340 operating days a year. A planning aid — results depend on brewery size, capacity and margins. Quality gains come on top.

Proven in production

A 20% faster fermentation

A well-known Swiss brewery brought Amphasys yeast analysis into daily production and cut fermentation time by about 20% — more consistent beer, and more runs per year.

“When yeast is happy, we end up with good beer.”

Repitch on a number, not a hunch

Repitched yeast can't be taken on trust — every crop drifts, and generation count tells only half the story. A viability read before pitching turns reuse into a decision: below ~65%, adjust the amount instead of finding out in the tank a day later.

How it works

Single cells, measured electrically

Each cell passes through a microfluidic channel and is read individually by electrical impedance — viable or not, no stains, no dyes. The scatterplot builds in seconds; the full read-out lands in about a minute.

How impedance flow cytometry works

Single-cell yeast analysis reads every cell individually instead of averaging the slurry: viable and dead cells, concentration, cells in active growth, and the ready-to-pitch amount — label-free, dedicated to brewing Saccharomyces via the AmphaChip Yeast.

FAQ

Frequently asked questions

Which cells can it measure?+
Any brewing Saccharomyces — ales and lagers (Yarrowia too, per the technical data sheet).
How is it different from other methods?+
Cells are measured electrically (impedance) — no staining, in about a minute, thousands per run. The read-out includes viable cells, cells in active growth, and an automatic pitch-amount calculation for the batch.
Can it be used on harvested yeast?+
Yes — a viability read before each pitch flags when a crop has dropped below ~65% and the amount needs adjusting.
At what viability should I stop pitching as usual?+
Below about 65% viability, adjust the amount instead of pitching as usual — the measurement makes it a decision before the batch, not a problem in the tank a day later.
Does it work for distilling or cider?+
Yes — same on-site workflow for any brewing Saccharomyces.
How fast, and any prep?+
About a minute. Take a sample from the fermenter, dilute it, measure it — minimal prep, no dyes.
How much faster can fermentation get?+
Doppelleu Brauwerkstatt cut fermentation time by about 20% after bringing yeast analysis into daily production. Typical gains range from 10 to 20%.

Pitch on the number

The beer is the brewer’s craft. Measuring the yeast — down to the single cell — is ours. See it on a real culture, or talk it through with a specialist.
