On the vexed subject of water chemistry…

June 2, 2012

I plan on brewing an IPA tomorrow so thought I’d check my water alkalinity with my trusty alkalinity Salifert Kit.  The blooming result was off the scale.  Greater than 400 mg/L CaCO3.  And as I don’t have enough CRS to get “de l’eau” into the desirable range I thought I’d try boiling it to precipitate out the chalk.

Chalk, chalk, chalk.

After boiling all my liquor for 10 minutes I got a beautifully festive dusting of white powder and an alkalinity of 136 mg/L CaCO3.  I suppose it will have to do… oh, how I pine for the soft waters of Scotland!
