First you need a set of equipment, now craft beer equipment domestic price is about tens of thousands to more than 100,000 ranging, basically to meet the initial use of a store, of course, the summer fire is certainly not enough, do not worry about no one to buy, this thing is absolutely hot in the summer, the investment will depend on the rent in your local area, if it is owned by the store then only need craft beer equipment and some raw materials (malt.), hops, yeast). Specific operation and technology and equipment issues, you can ask me, my craft beer house has been open for 5 years! I've been a craft brewery owner for 5 years!
