My wife and I visited last week, and had a great time. We've been to the DR a few times now and have always loved Barcelo rum. Maybe it's an American thing to want to take a tour of the place your favorite alcohol comes from, but we decided to look into it since I figured out that this tour was outside S.P. de Macoris, and we were staying near La Romana. It was about 80 minutes from our hotel in Bayahibe, and not too hard to find if you drive yourself (or you can book through Tequia Experiences to get a ride). You'll have to book your tour through them anyway, under $12/person (without transportation).
For the tour itself, you check out the storage warehouse where they age their Imperial line of rum. The smell is great, they should set up some lounge chairs and a bar in there. Then you check out where they repair the barrels they buy from American bourbon distilleries. Then you head inside for a walk through the company origins and the old way they made rum. Some interesting historical pieces they've acquired are on display. Then you watch a video about the manufacturing process. So you aren't going to wander through sugarcane fields or see the cane get pressed or distilled or bottled. Pretty sure that stuff all happens elsewhere anyway.
Next you go to their in-house bar where you do a tasting of 3 of their premium rums: Gran Anejo, Gran Platinum, and Imperial. You can watch some Barcelo commercials from the 90's too. If they aren't busy that day, you can hang around and talk to the tour guys about whatever. Rum, baseball, etc.
And finally, you're at the gift shop. Unlike every other "official" gift shop I've been to, the prices here are actually very good. If you want to buy any rum, here is the place to do it, because they have the best prices. A bottle of Imperial (which goes for $29 in duty-free at the airport, $34 at our resort) is less than $20 here. Would love to see some t-shirts with their corazon logo on it... maybe next time.
All in all, a great way to spend a couple hours. Thanks again to Jorge and Otto.
