Abstract
summary:A concrete category K is (algebraically) {\it universal\/} if any category of algebras has a full embedding into K, and K is {\it almost universal\/} if there is a class \Cal C of K-objects such that all non-constant homomorphisms between them form a universal category. The main result of this paper fully characterizes the finitely generated varieties of 0-lattices which are almost universal
