Baking soda and chalk? Why do you need two carbonate sources? Chalk won't dissolve at all unless there's some acidity and I've found it tends to react with phosphates in the mash and give you tiny crystals of apatite which then cause gushers in the beer. Dissolved carbonate is bicarbonate so general advice: Don't waste your time with chalk.finished up a breakfast brown ale last night around midnight. experimental for me, especially with water.
had a lot of oats and lactose, hopped with Amarillo at 5 and WP, and some sweet orange peel.
for water I did a healthy amount of baking soda and chalk into the DI mash water, I'm skeptical because one of those won't dissolve very well. overall, I went:
Ca......Mg...Na...Cl...SO4...HCO3
100....5......35..100...100...150

How much carbonate do you need? I wouldn't trust my feeble memory on how to dissolve chalk, I don't use it because of the gushing problem, but I know it involves acids. Or carbon dioxide. And by "overdoing" it on sodium, how much are we talking about? A few ppm won't hurt a thing and won't make your beer salty. If I'm reading between the lines correctly, you're doing a very dark beer and the pH is too low. Here are a couple of suggestions to deal with the problem without trying to dissolve chalk: First, RDWHAHB. And there's some science behind this: If your beer has a lot of roasted (black) grains, the calculator doesn't solve for them quite correctly, overstating their acidity. If you have a pH meter, check the pH and if it's in the range (5.2 - 5.6), do nothing. Second, don't mash the darkest grains, but add them at the sparge. This way you can adjust the water for the lighter mash (needing lower Residual Alkalinity), then adding in the acidic, black grains at sparge will keep you from over-sparging and extracting tannins. Third, since you're adjusting alkalinity, you can use sodium hydroxide (a much stronger base than calcium carbonate), or potassium hydroxide or potassium carbonate if it's really sodium you're worried about in addition to your mash pH. Nothing beats a good check with a pH meter once the mash has been in progress about 5 minutes or so. If your mash pH is above (or a tenth of a point or so below) 5.2, don't worry about it!What is the best way to dissolve chalk then?
if I use just baking soda I can't hit all my numbers without overdoing it on Sodium.
Ah gee she sure does look good in the sample there snook that with a nice tight creamy head that just keeps sticking to ya chops has gotta be a winner!Brewed an Irish Red Ale, similar to a Kilkenny. 1.054 and on the dark side of the color for the style. Going to serve 5 gal on Nitro and 5 gal on CO2. 1.054 as per plan.
