Traditionally used in English stouts, pale ales and bitters.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCalcium carbonate is also used to reduce the acidity of wine. It does not require cold-stabilization to force complete precipitation, as does potassium carbonate. However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) of calcium carbonate reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon. Wait 24 hours and rack wine. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Brewmaster","offers":[{"title":"2 oz","offer_id":48452904845529,"sku":null,"price":1.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0701\/1018\/3641\/files\/calciumcarbonate.jpg?v=1774296325","url":"https:\/\/homebrewconnection.com\/products\/calcium-carbonate","provider":"HOMEBREW CONNECTION","version":"1.0","type":"link"}
