葡萄酒亚硫酸盐计算器
Calculate how much SO2 or potassium metabisulfite to add to your wine based on volume, pH, and current free SO2 levels.
How to Use the Wine Sulfite Calculator __I18N_T_4__||Enter the volume of wine in liters.
- 输入葡萄酒的体积（以升为单位）。
- Enter the current free SO2 level (test with a kit or titration).
- 输入您的目标游离 SO2 水平。
- 输入葡萄酒的 pH 值。
- 单击“计算”以获得 SO2 和焦亚硫酸钾的添加量。
使用场景
- •压碎或压榨时使酒亚硫酸化。
- •装瓶前补充 SO2。
- •测试游离 SO2 后计算添加量。
- •在老化过程中调整亚硫酸盐水平。
公式
SO2 to add (mg) = (target − current free SO2) × volume (L).
常见问题
What is free SO2 and why does it matter?
Free SO2 is the active form of sulfite that protects wine from oxidation and microbial spoilage.
什么是典型的目标游离 SO2？
For dry wines, 25–35 ppm is common.
什么是焦亚硫酸钾？
K-meta (K2S2O5) is the most common form of sulfite used in winemaking.
