If you mashed up Google Maps, Yelp and craft beer? You would be lost, given 1 star but you would drink well. Alternatively, you can try HopPlotter, which is both a website and an app (and it is free!) Is it the map equivalent of Untappd?
I tested the web version at https://www.hopplotter.com/. HopPlotter has been around since December of last year so I didn’t expect that a full picture of breweries would emerge. But I did want to see if the press release info was correct and that the site was easy to use and if the information was helpful and accessible
Markers indicate where breweries are located and have colors signaling if they are currently open or shut.
The rest of the instructions from the press release: “Clicking on a brewery will lead the user to even more information such as the brewery’s top-rated beers, Yelp rating, Facebook posts, Tweets, whether they serve food, whether they offer brewery tours, whether you can bring your kids along, etc. The site also gives you the ability to plan trips and visits to breweries by letting users create and save itineraries to their own account. Itineraries can be anything from just a day to a long detailed trip. Not seeing your favorite pub on HopPlotter? Add it by clicking “Add a Brewery” on the webapp!”
My quick test run of three cities and obscure breweries did not faze HopPlotter (though the Brouwerij West a soon to open wasn’t marked, yet) and I loved the drag and drop VISIT icon that you can plan your day with. You really need to use it in full screen to keep all of the logistics in front of you but it works well. You can share it and then re-arrange as needed. It really gives you a visual look combined with hours of operation that I haven’t seen before.
