Okay not quite as much of a miracle as straight up water into wine, but it's a pretty great second. Turning water (and just a couple of other ingredients) into wine in about 3 days, is a much accelerated and greatly simplified way to make your own wine.
Setting you back a cool $500 the Miracle Machine hooks up to your smartphone. You choose your style and it'll tell you how much yeast and grape concentrate to throw in, and then in a few days it'll let you know how your wine has progressed and if it's ready to drink yet! This takes approximately all of the effort out of home brewing. If they can get us a 3-day beer machine too, we could really get into this.
If this needed to be even better, it comes from two wine industry veterans, and they're aiming for it to create decent wine, which is at the opposite end of the spectrum to how homemade wine normally tastes. The ingredients are cheap too; according to their website it'll cost just $2 to get the ingredients for a bottle of wine that you'd normally expect to pay upwards of $20 for. If you drink enough wine, this machine'll pay for itself in no time.
