So incase anyone runs out of alcohol you can make some pretty decent homemade stuff pretty simple.
Any fruit juice without preservatives just need to add some champagne yeast EC 1110 or bread yeast if you like and a yeast nutrient like DAP (Diammonium phosphate). Wait 2 weeks and then its party time. I have 2 gallons of apple cider fermenting right now that I will be carbonating shortly and bottling for hard sparkling apple cider for Christmas gifts or if SHTF it will be all for me! But please know what you're doing before you start fermenting your own food and beverages. I haven't bought alcohol since I learned to make my own. Look up and know how to make your own fuel alcohol, you can keep yourself warm or run a combustion engine, make sanitizer etc.
Im pretty self sufficient, if shyte goes down I hunt and fish and make alot of my own food and items at home. Self proclaimed inventor and southern engineer so I like to think I could live off grid if need be. Dad raises meat and egg chickens for us, I really dont buy meat from the store anymore unless its some kind of pork I can make sausage kielbasa or other charcuterie with. Make my own bacon and ham, lots of venison, moose, trout, salmon, perch, walleye, crappie etc in the close families combined freezers. I have a large garden that I pickle and ferment the harvest and eat fresh while in season. Pick and pickle wild asparagus that grows in the ditches everywhere...always learning something new pertaining to homesteading, not to be a prepper but to have good quality healtht items I can be proud of that I know what ingredients were used in the making of.
Like fratri said I dont see any doomsday scenarios playing out that will wipe out civilization "as we know it". I like to be prepared but some of those full on preppers are delusional and they get satisfaction in hoping the world goes to shyte. Maybe they repeal normal life and have a hard time fitting into society so they would rather see everyone burn. I just like to be prepared in the event of a natural disaster I am able to continue living in comfort until normalcy is restored.
