麦秆酒（英语：straw wine），又作麦杆酒、麦秆甜酒、秸秆葡萄酒、葡萄干酒（raisin wine），一种葡萄酒，使用风干后的葡萄酿制，以使葡萄的汁液浓缩。这种酒的制造原理类似于冰酒，但较适合温暖地区。制作方法随其地区而有不同，最常见的制作方法，是将收成后的葡萄舖在麦秆上，以日晒方式风干，之后再用于酿酒。也有将葡萄吊在屋簷或是放在谷仓里风干，或是让葡萄直接留在藤上，等晒干后再采收。

麦秆酒一般是制成甜的白葡萄酒。

Straw wine, or raisin wine, is a wine made 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, on roofs, or on modern racks, while some hang up the grapes or leave them to dry on the vine. The technique dates back to pre-Roman times, and most production of these wines has been in Northern Italy, Greece, and the French Alps. However producers in other areas are now starting to experiment with the method.
