Chalk (Calcium Carbonate)

    Description

    Calcium carbonate is 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. Calcium carbonate is also used in beer to increase the temporary hardness of water. Traditionally used in English stouts, pale ales and bitters.


    Usage: Usage varies with acid level

        I use calcium carbonate when I need to keep the mash pH from getting too low.

        Use it for buffering Lacto starters or mixed culture storage.

        How much more would it cost to include re-sealable bags?

        And I have looked everywhere. Most places want to sell you like 4 ounces in a bottle. Just get a mason jar and store it in that.

        If you're at the level where you're adjusting water chemistry or building from RO water, this will come in handy.

        Gets the water where it needs to be

        If your PH is low this is the ticket to raise it up, I don't use a meter just strips and it works great for me. You can nail just about any water profile you want with the right adjustments.

        Great for all grain brewing

        Pair this up with a pH meter and a couple other salts to really target the water profile you want

        a must have for allgrain brewing

        I use RO Water and you must have your brewing salts. Great to bring the PH up in when mashing with dark grains.
