Concierge.com's insider take:
When it comes to shopping in this part of Italy, you'll do better to contain the spending urge until you get to Milan, or even nearby Genoa. But what you can find in the Cinque Terre, in abundance, is local produce, especially wine and olive oil, both of which are cultivated on the steep terraces around and above the five villages. White wine has been produced here for centuries; the two main varieties, both obtained from a blend of bosco, vermentino, and albarola grapes, are the dry white Cinque Terre and Sciacchetrà, a delicate (and rather expensive) dessert wine made from partially dried grapes in the second half of October. Be wary of imitations, and if you're unsure, stick to the wines made by the local Cooperativa Agricola, which turns out perfectly correct, well-balanced examples of both genres. If you want something a little more refined, look out for two producers in particular: Buranco from Monterosso, and Bonanni from Riomaggiore.
