From beer advocate, it says that the XXX beer from De Ranke brewery is no longer brewed. (http://www.beeradvocate.com/beer/profile/739/97035/). It's no longer on their brewery page too: http://www.deranke.be/en/bieren_en.htm
It's not exactly the kind of belgium kind of belgium pale ale, famous for their bitterness, it's normally criticized for being too bitter in normal crowd-source reviews.
Sometime ago I saw this tweet that says XXX scored an IBU 70 (https://twitter.com/beergusto/status/435908275863687168).
Does anyone has any more information on the XXX?
And also how can I get hold of one now? Is there like a beer amazon or something?
