Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule. Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule. Catalysis of the transfer of a galactosyl group to an acceptor molecule, typically another carbohydrate or a lipid. Catalysis of the reaction: UDP-galactose + 3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol = UDP + 3-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-1,2-diacyl-sn-glycerol.
