I don't know if it's anything like El Inca, but here's a Schwarzbier I made recently that was delicious. It's very dark, but is super malty, light, and delicious. It's loosely based on Jamil's Oktoberfest recipe. If you want a little drier, I'd drop the Caramunich and substitute more Vienna or Munich. It's like a cross between a Vienna lager and a dry stout , and is extremely drinkable without any extended lagering time. (Since it's so dark, you can't really tell whether or not it's clear.
) I might have to make this again soon...
