Remember to drink like an Italian, but don't overdo it: A cappuccino in the morning, a shot of espresso around lunchtime, and one more after work hours should satisfy your need for caffeine without sending you over the edge. (Take it from me: I got caffeine intoxication in Rome after downing eight straight shots and lost half a day of touring because I had to sleep off the shakes.)
Caffe al Bicerin, Torino: The namesake chocolate-coffee confection alone is worth the trip.
The La Marzocco Factory, Tuscany: An espresso-machine museum greets visitors to the factory, where the pieces are still hand-crafted to order.
Sant'Eustacho il Caffè, Rome: What's the secret to this coffee? The baristas won't tell, and you won't care: Don't ask, just drink.
Although Carnival will fall in early February this year—a bit early to partake in both the revelry and the beginning of the coffee harvest, which typically kicks off around April—planning a visit around the party should still correspond with plenty to see on working coffee farms. Cherries will be just starting to ripen, and the larger operations will surely be in high-gear, prepping for the start of picking.
Take a break from snorkeling and drinking young-coconut water to walk through the idyllic clusters of coffee trees peppered on Kona. Half-day exhibitions around farms are often paired with other explorations, like peeking into the crags on the island's active volcanos, or you can plan your trip around the annual Kona Coffee Festival.
