I'll keep my eyes peeled for Titos. Never heard of it, but the wife and I are like to experiment with martinis.
Her favorite is Absolut Peppar (or any of the premium pepper vodkas) with a brush of vermouth (we always use Martini and Rossi (hence the name Martini). Garnish with some big Old Gilroy Garlic Co Jalapino stuffed olives. What a killer martini.
The best place I have ever seen to get just about anything brewed or fermented is the Cannery Wine Cellar and Gourmet Market near Fisherman's Wharf in San Francisco. It's the only place I have ever found Aguardiente (a Columbian anisette liquer) outside of central/ south america.
I'll be there in a few weeks and will look for Tito's.
