Open brew is not about brewing in the beer sense. Its about helping to create the right environment and mix to produce some really tasty Open Data projects.
“Open Brew is a movement for open data developers and creatives who are focusing on making open data projects happen.”
[Update Dec 2013] We ran the first Open Brew event in Nov 2013 and it was a bit of a flop! Check out Code For Ireland for a list of open data projects.
