Definitely worth a trip here to taste and purchase flavored and unflavored olive oils and unusual balsamic vinegars. The Tuscan oil is good enough to eat with just a piece of bread. In addition to olive oils, there was truffle oil, toasted sesame oil and I believe toasted almond oil, all available for tasting.
Normally I don't like balsamic vinegar, but I tried the coconut, peach, pomegranate and something else I forgot, and every one of them was not only delicious, but smooth in texture as well. The best part is you can buy a sample size of a few ounces so you can see if you really like it and have enough uses for your selection.
I hope they do mail order because I don't get to AZ often enough to enjoy all their goodies.
