My local HBS guy (Mal West at Western Suburbs HB in Chapel Hill, Brisbane) started off as mainly a K&K guy with a big love of distilling spirits. When a few of his more advanced beer brewing customers (me included) started asking for liquid yeasts, imported grains, more varieties of hops, etc, he started listening and soon was getting in all this, as well as fresh worts, mash tuns, false bottoms, etc. Now he puts out a "brewsletter" full of advice, hosted a customer "share the brews" party, sponsors competition entries for his customers, and has recently done his first full mash and is fully hooked! Because he listens to his customers, he has developed his own skills and now can provide expert advise to newcomers. He even asked me the other day for advice on a design for a simple, affordable partial mash system so he can get beginners off the K&K and start getting into grain brewing! Thus, his business is growing quickly and he has a lot of happy brewers in the Western suburbs, among others.
Definitely a recipe for success.
On the other hand, his direct competitor, also in the western suburbs, was surly, didn't want to listen (or even talk) to his customers, did no research into his industry and failed to grow. He lasted 1 year before going bust.
A recipe for failure?
