I'm new at the wine game to, so will be of little help. I've done 1 batch of dandelion, 2 batches of peach, 1 maple, 1 cranberry and 1 prickly pear mead. Each were 1 G batches. I let each age a year in the bottles before sampling.
It seems likely from your description that carbonic bite is a possibility, unless it's just a harsh alcohol bite that hasn't had time to mellow.
