During my many visits to Honduras, I have realized that Honduras does not, repeat, does not have a 'wine culture'. You'll be lucky to even find European wines that we take for granted, whether from the center of the universe (France), Spain, or Italy. You can find them but they're not very common. Totally forget trying to find wines from Australia, South Africa, New Zealand or Bulgaria. If the vintage is from an obscure locale, it's not existent in the Honduran world view.
The wines that are available are mainly Chilean, Argentinian, and Californian. You can find these at almost all grocery stores and they are reasonably priced, similiar to USA prices. The nice thing is that restaurants don't have the huge markup on wines that they have Stateside. An $8.00 bottle of Chilean wine in a supermarket will cost maybe $12.00-14.00 in a restaurant, compared to the obscene markup in the USA where an $8.00 bottle magically becomes a $28.00 bottle!
The problem is that since Honduras does not have a wine culture, you never know how long the bottles have been sitting on the shelf, whether the cork has dried out, and whether you'll be buying wine or vinegar. This has happened to me on several occasions where I opened my newly acquired bottle to find that it had as Monty Python so aptly put it, "the bouquet of an average armpit".
THE SOLUTION: Only buy wine from stores where lots of expatriates shop. In Tegucigalpa, I've found that there are always expats shopping at the Paiz store in the mall accross from the Intercontinental Hotel. They have a good wine selection, and I've never had a problem.
The problem of spoiled wine is even worse on the North Coast (think Tela, La Ceiba, and San Pedro Sula) due to the hot, humid client.
My ever enterprising wife has found an even better solution. She went to a wine wholesaler/importer and asked if she could buy wine there. They were happy to oblige as long as she bought a minimum of an assorted case. They even threw in a cork screw!!
