After Denny's thread on tips, maybe it would be interesting to share lessons learned from simple mistakes
On 12/1 I brewed a 1.040 Scottish and about 20 minutes into the boil I was looking at my work bench when I realized I used CaSO4 instead of CaCl in my mash/sparge water. Oh well, keep on trucking. I tapped it last night...
1. I really need to build my QD pressure checker, because its at about 2.8 volumes...
2. Even through the over carbonation I can really tell the difference between CaCl and CaSO4. I'm not liking it... obviously you can tell the difference between the two chemicals just by looking, but I need to put them in small tupperware bins clearly labeled so this doesn't happen again. Its like when you take a drink from a half gallon carton, expecting milk, but its OJ. That moment of WTF!!!
Anyway, I wouldn't normally intentionally brew with the wrong calcium just to see the difference. Accidentally doing it gave me a chance to learn the difference though. Also, its supported my mindset on WHY I add Cl or SO4. I do it to add calcium, and whether I add Cl or SO4 is based on the style. In other words, for me its less about trying to drive malt (Cl) or hops (SO4) its more about getting the adequate Calcium from a salt that doesn't get in the way of the malt (SO4) or hops (Cl).
What have you learned from a mistake?
