From a KDE event somewhere in 2017 I found this note in the KDE-booth-crate that I keep at home:
1. thin, sour, 4/10 2. slap in the face, gummi bears, fotlcs 5/10 3. citrussy note 6/10 4. aardberg, smokey x3 8/10 5. nothing happens, competent
I can reconstruct that this particular event had some whiskey, but except for the Ardberg I would have no idea what any of them were. There are no alcoholic notes from FOSDEM, except that we ordered a beer because it was described as "trés désalterante" and we decided after tasting that that was French for "pretty gross". It certainly quenched our thirst for more.
But if you're thirsting for more KDE events, there's the list of KDE Sprints which is where you will find the small, focused, fairly short events for hacking on a well-defined project. Some are open for visitors, and if there's something you want to hack on with a group of KDE contributors, get organising! (Like, seriously, getting a hacking weekend together is just a few phone calls to reserve a rental house somewhere nice and to arrange for transportation -- if you can get the people together, which is usually the biggest problem).
And of course there's Akademy 2018 in Vienna -- I suppose tasting notes will be of terrible coffee and that horrible Mozart liqueur -- which is the two-litre stein of KDE interaction each year. The call for presentations is open, so you can pour your wisdom, wit, or vinegar on the audience this summer.
