So the thought is this (disclaimer: no trials yet):
The malt flavor in the Low Oxygen brewing environment is intensified when it comes to cara Malts and roasted Malts. We've sort of been touching on this for a while now.
This is going to be very apparent with CaraMunich type Malts, Carabohemian, Special B/CaraAroma, etc. By selecting Malts that will give intense layers of dark caramel, dark fruit, toffee, raisin and dark chocolate flavors, my theory is that the characteristic flavors of dark syrups can be supplanted by the Cara blend/Sucrose combination.
Color can then come from a modest dose of Sinamar, due to the fact that the Low Oxygen color reduction and absence of color contribution from syrups means a max SRM in the low teens. No issues for pale beers but Dubbel and Dark Strong will need a bump.
Sugar will still make up a big portion of fermentables but I'm looking for the interesting flavors to come from the malt.
I've flagged the following ingredients for use in my trials based on the Weyermann Malt color wheels and our work with the base malt blending:
All Weyermann:
Pilsner
Pale Ale
(These will form a blend that combine for 5 EBC. These two together essentially for a custom EBC Pilsner malt like many big breweries specify)
CaraMunich II
CaraBohemian
CaraAroma
Sauermalz
Sinamar
Essentially the Table beer and Tripel will get the base malt blend, a touch of CMII to adjust color, a dose of plain sugar, and enough sauermalz to hit mash pH.
Darker beers will get the base malt blend, a mix of the 3 cara Malts, either table sugar or turbinado, enough sauermalz to hit mash pH and a touch of Sinamar to adjust color up.
That's the plan at least.
