You would have to go to a local winery and since you havent filled in your location field its very hard for us to help you cause we dont know where you live! Onless you want this barrel shipped from Germany or Italy!
Here is a link off Google, Its probably to late now to get any from these as that season is over but you could go taste some of these wines at tastings and then youll know who has better stuff and hit them up when they are in season. http://www.catchwine.com/wineries/kentucky/
