Sodium hydroxide (NaOH) solution is the titrant used in titratable acidity testing for home winemaking. This 125 ml refill bottle provides enough solution for multiple acid tests and is pre-measured to the correct concentration for standard acid testing kits. An essential consumable for any home winemaker who tests must or wine acidity.

Winemaker's Tip: Label your NaOH bottle with the date you opened it — sodium hydroxide solution loses strength over time through CO₂ absorption from air. Replace every 6–12 months for accurate results.
