Question about (accidental) vodka in mead

I just racked (for the first time) my first batch of mead. It's 5 gallons lavender methelglin, basically a recipe kit from my local homebrew shop. I added 2.5 tsp potassium sorbate and a little less than 1/4 tsp sodium metabisulphite. As I was placing the carboy in the closet, some cheap vodka from the airlock spilled into the...is it still must? I just want to know, will that ruin the mead?
