So one of the nice things about home brew is that it is a nice saving over the cost of buying beer in the supermarket. Even the double kits are obviously still cheaper, but have been wondering about some of the single tin ones. Obviously you need to add sugar and I've read on here that using a beer enhancer makes them better which adds a fiver or so to the cost of the beer. Do folk just use this or are there other good options? What are the more budget friendly recipes that you may have tried? When it comes to adding hops then what have you found that has the most success?
