I got a bottle of Lustray bay rum, and for the most part I really like it.

However, it leaves a residue that is mostly unnoticeable except for the terrible, terrible taste. I try to prevent any of it from getting on my lips, but I seem to always get a taste of it at some point. Is this a characteristic of all bay rums, or is it because this brand uses denatured alcohol (I assume it uses denatured alcohol). Are there any bay rum brands that do not use denatured alcohol or do not leave a terrible tasting residue?
