This puts me in mind of “apple wine” my dad made years ago, following instructions in a magazine. Successfully, too.
We went to the apple growing region in our area and obtained 5 gallons of raw, untreated juice. Dad drilled a hole in a large cork, put a length of plastic tubing through it, set the cork in the bottle opening, then sealed it all over with wax.
The other end of the plastic tube went in a jar of water. As the juice fermented, the bubbles of carbon dioxide went up the tube and came out in the water, perfectly air-tight. The instruction was to count the number of bubbles per minute. At a certain point it was time to bottle.
Dad and Mom had collected old champagne bottles for this purpose and they were duly filled and capped, then store for some time longer. The resulting “wine”, as it was called, was light, bubbly, refreshing, and had the slightest hint of apple flavor. Ah, memories.
