Straw Wine, or raisin wine, is a wine mae from grapes that have been dried to concentrate their juice. The result is similar to that of the ice wine process, but suitable for warmer climates. The classic method dries clusters of grapes on mats of straw in the sun, but some regions dry them under cover, some hang up the grapes, and the straw may be replaced by modern racks. The technique dates back to pre-Roman times, and most production of these wines has been in Northern Italy and the French Alps. However producers in other areas are now starting to experiment with the method.
