Get your brew started in minutes with the SimplEST Brew Kit. Everything you need to turn juice (or any liquid with sugar) into alcohol. Includes yeast (to ferment the sugar), two stoppers (small and medium for different size openings), an airlock (to release carbon dioxide while keeping bad guys out), a small packet of cleaning powder (to clean the stoppers and airlock between uses), and instructions.
Just buy juice, remove top, add a pinch of yeast, install stopper and airlock, wait a week or two, and enjoy drinking your hard juice. Wow your friends with your ability to turn water into wine (or something like that). Depending on sugar content, acidity, and length of fermentation, the alcohol content will be in the 3% to 7% range.
