6 lbs of Wheat Dry Malt Extract
1 oz of hops (Hallertau, Tettnanger or Saaz)
1 Vial of White Labs Hefeweizen Yeast (WLP300)
cheapest, easiest and one of the tastiest brews. if you want, you could add 1/2 oz of hops at the last 5 minutes of the boil to make it more of an american style. you could also go with a different yeast (this is a german style yeast)
i also steep about 2 lbs of munich with this recipe...it makes it taste really good.
try to keep fermentation below 70, absolutely below 75
