Water Activity Meter Aqua Gauge

Water Activity Meter – Precise Control for Perfect Coffee Production

RoastSee AquaGauge is the ultimate tool for coffee producers who demand uncompromising quality. Equipped with advanced MEMS humidity sensors and a specially developed metal oxide coating, it delivers precise measurements 50% faster than standard models. In AW QuickMode, you get results in 1-2 minutes with an accuracy of ±0.01 AW, allowing you to optimize roasting, storage, and quality at every stage of production.

Why use RoastSee AquaGauge in coffee production?

✔ Preserve Freshness and Flavor: High water activity in ground coffee degrades aroma and flavor nuances. Regular measurements ensure optimal storage conditions and protect quality.

✔ Perfect the Roasting: Water activity in the range of 0.4-0.6 is ideal for a controlled Maillard reaction, which drives flavor development. Measure water activity in green beans to fine-tune the roasting process, avoid over-roasting, and achieve the perfect flavor profile.

✔ Extend Shelf Life: Control water activity to prevent mold, yeast, and microbial growth. Measurements help you choose the right packaging and protect products from moisture.

✔ Optimize Storage of Green Beans: Freshly harvested beans have high water activity and unpredictable flavor. After 3-6 months of storage, water activity stabilizes, providing more predictable and optimal roasting results.

Why Water Activity is Crucial

Water activity (AW) measures available free water, which affects chemical reactions and microbial growth. In coffee roasting, water activity acts as the driving force behind the Maillard reaction, creating complex flavor nuances. Too high AW (>0.6) can make roasting unpredictable, while too low AW (<0.4) inhibits flavor development. By measuring AW in green beans and finished roasted coffee with LeBrew RoastSee AquaGauge, you can control the drying phase, optimize the roasting process, and ensure long shelf life without quality loss.
