Kriek is the cherry flavoured one, and Framboise is the raspberry flavoured one. They're both flavoured versions of a Belgian style of beer called Lambic which is a beer that was traditionally made using "spontaneous" fermentation with airborne yeasts. It's pretty yukky IMO in it's unflavoured state, a bit of a sour flavour somewhat reminiscent of sourdough bread. In Belgium, you can also IIRC get other fruit flavours like Blackcurrant and Banana although I haven't seen those here in Ireland.
