For thirsty oenophiles, a new invention out of the Swiss École Polytechnique Fédérale de Lausanne might just be a godsend. Requiring only grape juice and small compartments of yeast, the machine can produce wine in a mere hour compared to the typical one to three weeks of the traditional fermentation process. The downside? It only makes one milliliter of wine per hour, which means you’d have to wait nearly a week to enjoy that glass of wine. Oh, and the machine won’t be available to the public any time soon.
