You don't need to buy any of those fancy kits, one of my teammates has one and it seems like the ingredients and recipes it comes with are subpar. My buddies and I just use a big pot to boil everything in and then let it ferment in a five gallon bucket, and we find our recipes online and have made some pretty good beers, especially considering we just started a little over a year ago. There are a few pieces of brewing equipment you do need to go out and buy though, so maybe those kits make it easy if you're just getting started. This link does a great job of explaining everything.
I been thinking about home-brewing for year now, visited a couple websites about brewing and stuff along the years , But i'm leaning towards Mr.Beer mostly because i never brewed before, and i just want to get a feel of brewing, if anything i will waste $60 and two batches of sh!tty beer hahuau..
But if i really start to enjoy brewing i will be doing the more traditional approach, buying the hops unstead of the MrBeer mix and so on.
My Grandma used to brew a Non-alcahoolic beer, she used two kings sized bottle of balck- non alcoohilic beer, mix with hops and stufff i dont rmemeber now. then she would put the mix on a 5 gallon used paint container. let stand for a week or so. then she would bottle the beer into used 2 liter soda bottles and let ferment ther for one more week.
It tasted great the downside was i don't think my grand make really measured the sugar she put on the bottles so 25% of the bottles would eventually explode i mean really explode due the pressure building up.
