Beer Events in Helsinki - May 2019?

Was planning to go up to Oulu next summer and rent a cabin with my parents, however this has been scuppered as one of my cousins got in first and announced they were coming to visit us. But, after a suggestion by my Mother, my wife has said she’ll provide me with both a pink pass and a return ticket to Helsinki as a 40th birthday present. Are there any events on during May of next year? I vaguely remember something about a Sahti event at that time of year.

Did mention it to some mates but kinda thinking a solo ticking trip may be better.

St Urho’s Sahti Days is in mid may.

It’s not as good as Tallinn Crap Beer Festival though, which is at the start of the month. Allegedly.
