I have one fermenting now that was made with about 65% munich 2 the rest pils and 1.6% Carafa Spec 11 for about 31 EBC. Light for a dunkel but within specs and how i wanted it. I mixed the munich 2 and pils to get a close aproximation to munich 1 which i dont have ATM.
After trying a dunkel brewed by goatherder that was All munich 11 with a bit of carafa Spec in it, i was hooked on the idea. So full of flavour but so simple.
