The Koloa Rum Company Tasting Room and Company Store sells all of the company's products as well as a number of other Kauai-made and distinctive food and beverage products. They also operate the only manufacturer's rum tasting room in the Hawaii.
Koloa Rum Company produces a number of products: Kaua`i White Rum, Kaua`i Gold Rum, Kaua`i Dark Rum, Kukui Brand Mai Tai Mix, Kukui Brand Jams, Jellies & Syrups, Koloa Rum Cakes, Koloa Rum Fudge Sauce and Koloa Rum Logo Wear, all of which and more is available in their company store at Kilohana Plantation.
If you're visiting Kauai, be sure to check their website for their current hours. Generally, tastings are held every half hour starting at 10:00 a.m., but ending at different times throughout the week.
As tasty as the rums seemed to me, I am no expert on rum, but for someone who is, I suggest Chip Dykstra, aka The Rum Howler. You can read his reviews of Koloa Rum on his blog.
Currently their rums are primarily available only in Hawaii, but if you're lucky to live in Southern California, you can purchase their products at Hi Time Wine Cellars in Costa Mesa.
From the Koloa Rum Company Tasting Room and Company Store it was just a short walk to my next stop, the Kauai Plantation Railway.
