Notes

Using 5lb Flaked Kernza from Liquid Poets meeting. It is said to have lower impact on extract and more on flavor. I've added it custom as 'Flaked Oats' and reduced the ppg to 23.

Some other info I've heard, kernza can impart a sort of 'spicy' flavor, similar to rye. So I thought use it to replace part of the rye malt in this recipe:
https://beerandbrewing.com/jds-roggenbier-recipe/

Using Troubador's Serenade as the base malt.

Two packs of M76 since gravity might be a little above 1060.

Ferment at 51F for 3days, then raise to 63F, 1F per day
Around a week at 63F gets us 21days. Maybe wait another week before racking for lagering.
