Two of my favorites, that I haven't been able to find here in the States are both from Germany.  Ratzeputz - a high-proof primarily ginger flavored liqueur with a long fiery finish, and Escorial Gruen - a light-green herbal liqueur. When I was first in Germany in 1963, my "associates" thought it was great fun to haze the new guy with a shot of "Ratsp*ss."  I, however, being a fan of ginger, LIKED it, and ordered another, much to their dismay. Escorial Gruen (that "ue" is actually a "u" with an umlaut - two dots - over it), was sorta on the same order.  I liked it, too. Would like to find both - along with some Austrian Stroh rum. Jim
