Weeeell, i do mostly partial mash recipes and here is what i use and the costs:
Ale pale, i have three of these with spigots. I use them as primaries, secondaries and bottling. 13 bucks each
Turkey fryer, big aluminum pot and burner. I get about 4 batches per tank of gas; 35 bucks
Propane tank(not included with fryer) 30 bucks full
5 gallon bucket, general use, transporting water, washing utencils etc... 5bucks
Big stainless spoon, bought it at local HBS for 14 bucks
Thats all you need for partial mashing.
Now that gets you to the bottling/kegging phase.
If your bottling i reccomend you go on a bender with a couple of buddies and drink grolsh all weekend. This is expensive and the beer aint great but the got good bottles for homebrewing. And its almost as cheap as the bottles empty if you buy them.
You could also drink alot of recappables. I started on bud american ale. I got about 6 cases now.
I reccomend however that you start kegging. Get you an old fridge and the single tap conversion kit from the beverage factory. this option is about 350 bucks but you wont regret it. Your gonna end up there anyway, i swear to god. I dont know antone that makes more than a few gallons who doesnt.
If you dont though you need a bottle capper(14bucks) caps usually come with the kits(brewers best are my fav).
Lotsa star san(18 bucks for 32 oz)
Racking cane, bottling wand and plenty of tubing(15 bucks
And the rest is kinda up to you.
I know it seemslike alot but it aint.
People are gonna tell you to get carboys, better bottles and a bunch of other stuff you dont need though. Just use the ale pales for now. I make 10 15 gal a month in them without issue and have for 2 years now. Good luck and welcome to the obsession.
