Sounds like the biggest expense would be the extra refrigerator to store the beer in after it is brewed. I'm thinking it needs refrigeration....
I spend 10$ a bottle for my favorite beer (I think it's 750ml). I don't mind spending money on it if it taste good and I enjoy it.
It seems that maintaining the proper temerature here is only feasible during the winter months and even then the range might vary too much as we have seen 85 degree days this January already (very unusual).
Since people have been making beer or somthing similar for about 5 thousand years....how hard can it be?...and now that I know I can't poison myself.....I just might give it a shot, maybe I'll become the next Jim koch...without the start up capitol.
I have often thought about brewing beer but never really did enough research. I'm the type to learn everything, work out every last detail..... before I start.
I memorized the budweiser can not long after I was old enough to drink legally, so I know about the "exculsive beechwood aging process...."

"produces a taste, a smoothness, and a drinkability you will find in no other beer at any price"
I also remember that Anhauser Busch used rice to make the beer.
Ever use rice in the wort?
