Digital pH Meter
The instrument that tells you if your wine will age — or turn brown.
≈ $35–$49price range
pH is the single most important number in your wine after specific gravity. Too high (above ~3.7) and you'll get oxidation, browning, and microbial trouble. A digital pH meter gives you a precise reading in seconds.
Calibrate it before each session with the included buffer solutions. Treat the probe gently.
