I've read (read: glossed over, because it's largely irrelevant to most brewing) about ways to calculate diastatic power, but from what I gestalt, with modern highly modified malts, it doesn't take much base malt to convert most adjuncts. If you're wanting to be conservative, perhaps use some 6-row barley (which has more enzymatic power than 2-row).
Packaged: Dry pipeline...it's been a crazy summer...

Bulk Aging: Cocobochet, Wild Cider
Planned: Some sort of SMaSH. Otherwise, so many ideas, not enough time to brew them....
