french burgundy with concerns

[Casta]

I purchased a bottle of fine burgundy a couple of years back:
Gevrey Chambertin-1er cru la combe aux moines
(1996)
I thought I was keeping it well, but I noticed recently that the there are some formations inside the bottle (may be fruit). Since I can't remember if it was meant to have them inside, can anyone let me know if the bottle is ruined.
