Strange Taste Developing...

I've got a weird, bubblegum-like taste developing in the Christmas ale I brewed about two months ago. It tasted great (nice and spicy!) after three weeks of carbonation, and I cracked on open tonight to see how it was comin along and discovered this funky development.

I ferment in my basement where temps stay between 60 and 62 degrees. I've heard that high fermentation temps can cause the bubblegum taste, but I didn't think it was slow to develop (nor did I think my temps would cause it).

Could this just be a one bottle deal? What could cause this? If not, will the taste diminish with time? I'm a little bummed cause I thought some of it would make great holiday gifts for my brew lovin friends.

Thanks!

More information on your recipe would help us out.

PS - If you're looking for a good recipe book, the owners of my LHBS (www.maltose.com) wrote Beer Captured, which has about 100 homemade recipes for commercial beers, as well as a "Cooking with Beer" section. Fun book.

I'm going to take a stab in the dark and say it's probably the spices you added. They might neeed more time to balance out and blend into the flavor of the beer.
