I'm looking for free online beer-a-day calendars highlighting a different beer every day. Anything available for the United States, Germany, Bavaria, for example? Ideally the calendars also include a web feed for subscription. Any insight welcome. Cheers. Prost.
I don't know of anything, but if you already have code to do one and just need data you may be able to leverage BreweryDB's API and scrape beers that way. It's a pretty extensive database.
You could use flickr Beer Nation group. https://www.flickr.com/groups/beer_nation/
Then subscribe to a feed. https://www.flickr.com/get_the_most.gne#rss
This way you will get pictures of beer every day. If you want to use their photos for your own calendar you are allowed to do this according to flickr's rules. A quick Google of github.com, lists some open source repositories you can use.
