The only saison I've bought was a smoked version whilst visiting Pipes brewery in Cardiff. It was very nice - enough so that I brewed my own. First off was a biere de Garde from the Greg Hughes book (B de G is a variety of saison from northern France). I was very impressed - very fruity with banana flavours. Plenty of body. Mine was 6.5% ABV. Only down side was that the yeast, a smackpack of French Saison cost �ã6.75!!!!
So while I still had the trub from the first brew I got a second out of it but this time I added in some cherry smoked malt. Result was very good, still with the banana flavours, but with an added touch of bonfire.
I can't see the point of adding fruit to it though as it would surely overpower the yeast flavours, and if you're paying that much for yeast you ought to get the most out of it you can!
