I like that that map is very simple, uses the basic Google Map navigation tools and contains simple push pins used to drill down for more information.
I think that the site would benefit from custom pushpins to further add branding to the overall user experience.
Map da CACHACA
UPDATE
This month I had a chance to revisit Mapa da CACHACA and what a nice surprise. This site continues to evolve making it interesting, easy to use and fun. This site moved from the standard Google Map view to a custom base map that gives the reader a warm feeling fuzzy feeling adding a touch of nostalgia to the experience. They have also added custom pushpins that further make the appearance one of their own and along with clustering makes drilldown and selection easy and intuitive.
I think that this points out a great strategy during development. Get your application out early listen to what your readers are saying and continue to evolve the overall experience. If the site flops then move on to something else.
Great going Mapa da CACHACA
