as needed Water
small amount for precipitation Optional: potassium bicarbonate

Method

Note: True cream of tartar forms naturally on wine barrels (lees) → home extraction is limited but possible from high-tartaric wine.
Use dry white wine with high tartaric acid (or ferment grape juice with wine yeast 2–3 weeks).
Let wine sit undisturbed in cool place 4–8 weeks → potassium bitartrate crystals (cream of tartar) form on sides/bottom.
Carefully decant wine → collect crystals → rinse gently with cold water → dry at room temperature or low oven (40 °C).
Grind dried crystals to fine powder → store in airtight container.
Alternative: buy cream of tartar raw → or use lemon juice/vinegar as substitute in recipes.
Makes small amount — natural potassium bitartrate for stabilizing egg whites or baking.
