You can use this simple 8 minute Youtube video to get started making your own wine. Bread yeast may make a 7% alcohol wine but it will be primitive and taste a bit like bread. Wine yeast will ferment to 18% which would be 36 proof.
Save the juice you pour into a jar in the fridge until the fermenting is done. It can be added back in later when the ferment has finished and the wine is racked (meaning the wine is siphoned off to leave the yeast residue in the bottom of the plastic fruit juice bottle) Just add it in a little at a time to taste.
Something that isn't mentioned is adding a couple of ounces of food grade glycerine. (a lot of wines have this which is called a "glycerine finish") It make for a smoother more mellow feel in the mouth when you drink it.
There are lots of different wine making yeast by different companies. Lalvin 1118 and North Star Premier Classique are two of the best for this kind of wine making.
For the Beer making I like the German Vierka Lager & Munich (dark) beer yeast.
You don't have to have a bunch of expensive equipment and there are simple tutorials on the net that explain how to get decent results with minimal effort. Beer making is a bit more complicated. I like dark beer myself and the head on a beer that I pour is as dense as the meringue on a pie. It is real beer
that conforms to the 1500 ad German purity law where the beer has to be made only of four ingredients....water, malt, hops, and yeast. Called the "Reinheitsgebot" Law. Not like the stuff you get in a can or bottle at the store. People ask if I can make anything as good as "Bud Lite", I tell them I don't make anything that bad.
The 100% Grape wine I make taste much like Mogen David or Manischewitz Concord Grape wine.
