So, if I understand correctly, a grain needs to have above 35 °Lintner to self-convert. Also, when using adjuncts, you need to raise the diastatic power of everything in the mash above this - ie, 1 pound of a 150 °Lintner 2-row plus 2 pounds of rice will have an effective diastatic power of 50 °Lintner. Is this correct?
How do you calculate this? It's easy when you just have one base malt plus adjuncts. Plus, I suck at math...
I did my first adjunct heavy beer this week, and it got me thinking. Search didn't turn up anything really useful, but I probably didn't use the exact right combination of search terms.
