Wine in 2 days

Turning Welch's Into Wine In 48 Hours

But I had to test the claims of Spike Your Juice, a yeast-based kit that ferments any 100% fruit juice, so long as it has 20G of sugar or more per serving, into an alcoholic brew with anywhere from 4-14% ABV. That puts the resulting potency somewhere between beer and wine. With a healthy 30G of sugar per serving, Welch's is a prime candidate for home fermentation.
Just an hour ago, I decided to pour a bit on the rocks since it fermented at room temperature. I tentatively sipped, expecting something that I could barely swallow. Instead, I was brought back to my childhood. Grape freezepops, grape sodas, grape jelly...but with a kick at the end. I wouldn't call it a burn, but a microbrew-like presence of alcohol behind the flavor.
After 2 1/2 glasses, it makes for a quick, harsh buzz—akin to the helmet of weight you get around your brow from vodka. There's no way this is 4% ABV—I'd guess it's closer to 8 or 10%.

From Spike Your Juice:

...was developed by a group
of Europeans living in California.
Having grown up near wine producing regions, they particularly craved a seasonal drink called “Federweißer”. This drink is only available from early September to late October during harvest time.
The original Federweißer is known by many names, depending on what wine region of Germany, Austria or Italy you are in.
