Absorbance One
Portable, Laboratory-Grade Wine Analysis


Mobile analysis for Vintage

The Winechek Absorbance One brings true laboratory-grade accuracy to the palm of your hand. Disrupting the traditional model of centralised lab equipment, the Absorbance One’s ultra-portable design, minimal footprint and accessible price point make advanced analysis available to everyone, everywhere. Purpose-built for wine analysis, it functions as a decentralised, mobile cuvette photometer designed for fast, accurate, absolute and quantitative enzymatic testing.

Custom-engineered to connect directly to your phone or laptop, the Absorbance One enables winemakers, consultants and technicians to run reliable enzymatic analysis in real time, from the lab bench, winery floor or the vineyard truck. Winechek’s customised Absorbance One software has been specifically optimised for the full suite of Vintessential test kits, ensuring precision, repeatability and commercial-grade confidence across Free and Total SO₂, Glucose/Fructose, Malic Acid, Acetic Acid, Citric Acid, Gluconic Acid and more.

This is modern wine analysis: mobile, accurate, immediate, and accessible.

FAQ'S

The Absorbance One is a handheld single-wavelength photometer for enzymatic wine analysis. It requires no warm-up time and auto-calculates results, unlike standard spectrophotometers.
Common tests include Free and Total SO2, Glucose/Fructose, Malic Acid, Lactic Acid, Citric Acid, Acetic Acid, Sucrose, and Gluconic Acid.
Validation shows results within ±3 ppm of NATA-accredited aspiration methods for SO2, delivering commercial-laboratory accuracy in a handheld device.
Vintessential kits use blanks, standards and baseline corrections to eliminate drift and cuvette-variation errors.
Onsite results take about 30 minutes, compared with several days when using remote laboratories.
