Even better, you can probably make a deal with the bars to hold wine bottles for you, or fill up a case every other week, or whatever rate would match your wine output. They'd probaby be happy not to throw it out. Don't know how much corked wine is consumed there (as opposed to screw-caps,or other spirits, both of which are not made to take a cork).
Then, you could mail order corks, and perhaps a hand corker, both of which are light enough to carry horseback.
Good luck. Sounds like you're in a beautiful place.
