i researched some baltic recipes a couple of months ago and found this one:
http://www.skotrat.com/skotrat/recipes/ale...recipes/16.html
so i tried making something similar to it (couldnt get choc rye) but the cold steeping was WAAYYY inefficient and i had to boil down heaps of extra liquid from cold steeping, PLus i got crap efficiency in my main mash cause i used powells munich, anyway to cut a long story short im currently lagering a schwarzbier by accident (only got to 1055 OG!) seems like a nice schwarzbier anyway.
also i got the recipe from a guy on the web for "Perkuno's Hammer" which is a baltic porter made by Heavyweight in the states, apparently a real good one [http://www.heavyweight-brewing.com/beers.html] and here it is if you're interested.
82% munich
5% chocolate
13% crystal
+ (and here's the weird bit): 450g borlotti beans in the mash!! (you have to cook them first)
OG 1085, northern brewer and hallertau hops. they use the andechser lager yeast which is impossible to get but WLP833 would probably do a good job.
