Stop in for a drink.

So maybe this eclectic conglomeration of connoisseurs is the correct assembly to help me out. About 10 years ago the diplomatic attache to Mexico sent me a bottle of the best tequila I ever had. Even straight and warm it went down like water. I thought I remembered 100 anjos but the stuff I find like that is low grade. Any idea what it might have been? Signed, Lost in a memory.
