Sugar cane and rum are big business on Puerto Rico. Locals love piña coladas, mojitos, coquitos (the Puerto Rican version of eggnog), and daiquiris—all of which are made with rum. Don Q and Bacardi both offer tours—complete with tastings—that will transport you back to the romance of early 1900s Puerto Rico. At Casa Bacardi in Cataño, just outside San Juan, you can watch a documentary about sugar cane, the rum-producing process, and the Bacardi family; study old letters and furniture; smell diverse rums in their barrels; and watch a mixing demonstration. Casa Don Q in Old San Juan invites you to read about the rum-making process, and listen to an explanation about different Don Q rums and how to mix them.
