Wine Refractometer with ATC 0–40% Brix and 0–25% Potential Alcohol Tester

Take the guesswork out of winemaking and make better decisions from grape to fermentation. This wine refractometer gives winemakers and grape growers a quick way to check grape juice sugar levels and estimate potential alcohol from the original must. Its dual-scale Brix refractometer displays 0–40% Brix alongside a 0–25% potential alcohol scale for convenient readings. Built-in automatic temperature compensation helps maintain consistent measurements as ambient temperatures change. Compact, battery-free, and easy to focus, it’s ready for testing at home, in the vineyard, or around the winery.

Key Features

• Dual 0–40% Brix and 0–25% potential alcohol scales simplify grape must testing.
• Built-in ATC compensates for ambient temperature changes from approximately 10–30°C.
• This grape sugar tester helps assess grape juice sugar and estimate the wine’s potential alcohol level before fermentation.
• Adjustable focus, comfortable rubber eyepiece, and ambient-light operation make testing simple without batteries.
  
  

Why Choose Our Wine Refractometer

Unlike basic single-scale testers, the RZ121 combines sugar and potential alcohol readings in one compact handheld refractometer. Its dual-scale optical design and ATC provide practical, convenient measurements wherever your winemaking takes you. Please note: it estimates potential alcohol from grape must and is not designed to directly determine the alcohol concentration of finished wine.

Perfect For

• Home and craft winemakers
• Vineyards and grape growers
• Checking grape juice and must sugar levels
• Monitoring grape maturity before harvest
• Estimating potential alcohol before fermentation
• Small wineries and winemaking enthusiasts
