Looks like it didnt work as planed, i got my self a bottle of orval, it was from august 2011 so not too fresh but not too old for belgians standards. Let it sit in the fridge for two days then pour in the glass and added 1.035og wort to clearly visable yeast sediment, swirl it and transfer to the flask, total was 150ml. After 24h on stir plate i dont see any activity and og is the same as at pitching, any ideas what went wrong?
