Prohibition and stills were largely regional in nature for want of a better term.
Sears, Montgomery Ward and hundreds of others sold block tin lined copper stills by the thousands, I still have one that was employed well by the 108th NY War of Northern Aggression reenactors, who were dumb or drunk enough to burn the block tin off by using it over an open fire. I was nearly expelled from 7th grade for setting up a still in Science which produced quality product according to 2 teachers who sampled it and appreciated my knowledge of the process sufficiently to keep the District from sending me down the road. Hey, nobody posted any rule about not making double pass liker for the science fair and nobody else was using all that glass.
When I moved on to boy's prison high school I made a little money on the beer side. I had roughly 100 gallons working under the auditorium for 2 years, since it afforded ideal cellar temperatures, and quality beer wasn't necessary to keep classmates happy. A lot of the guys carried 12 ounce milk cartons all day. It was funny on assembly days when the alcy teachers were getting wiffs of fermenting beer via the air vents under every 3rd seat and jonsing for a beer. Fortunately most didn't understand "fresh" air was blown into the auditorium via the pressurized cellar.
Vinyards being ripped out for Prohibition is a bit of a stretch for me. Some grapes were grown around here for years, and they all went to Gerber, Beachnut and Duffy Mott. From my recall, vines are only productive for a limited number of years and then get replaced. As I recall it's a two step deal since a vine on new roots takes about 2 or 3 years to be productive. First and sometimes second replacement will be a new vine grafted to an established root. If it takes the vine is producing in 1 year.
Wine grapes tend to be different variety from Jelly grapes too.
I'd say probably 100 new varietys of grape have been developed by Cornell alone since I was a kid. Today we grow apples on what look like grape vines on wire about 100 acres of which are on old grape land.
I've retired from Jelly making, and given my lightning mixer to a lady who sends her husband over to borrow a small compressor to power it every year.
BTW, you can make an excellent grape, cherry, strawberry or mint jelly from apple cider. Lot less labor and lower cost too.
Personally I always liked Shimmel's commercial grape jelly better than Welches.
