I have grown using old wine corks in slat baskets before. This works pretty well if you drink a lot of wine (I've switched to wine in a box... *grin*).

Oh, I definitely drink enough wine. Time to start saving the corks.
I have had great success using wine corks as medium for growing some of my drier growing plants.
As an aside, one of the reasons a cork is presented to be smelled is not for the wine, but for "freshness" (as in not infected or fermentation to the point of vinegar)! I seem to recall the cork infection also affected the vintners, hence the move to synthetic corks.
