BiloxiBrew, small world, I was born/raised in Ocean Springs. Right accross the bridge from you.
Thankfully the beer law has recently changed in MS, but i'm not exactly sure if theres been a homebrewing bill made along with it. Under MS law, it does not state that it is legal to homebrew, but it does state it is legal to make homemade wine up to (i believe) 14%, but gives no stipulations as to what is 'homemade wine'.
There is a brewery in Kiln, MS you definitely need to check out, Lazy Magnolia Brewery. My favorite they make is Jefferson stout. They used to sell grains and hops and whatever else to home brewers back when i Interned there in college. Which has been a while, but they still may continue to do so.
I'm sure your enjoying the blistering heat and humidity, ahhhh what I don't miss about Mississippi....
