Recently taken to Scotch whisky and tried Naked Malt (formerly The Naked Grouse) tonight. Had early watched a review on YouTube that spoke to a rubber note in it, and I detected that on my first dram, before adding and then after adding a small amount of water. Most say that I didn't care for that. Just poured another dram and added a bit more water than before. Now I am getting it less on the nose an very little on the palate. But was wondering if anyone knows would would cause a rubber note? Naked Malt has been reviewed as a sherry-bomb. I do think it has more sweetness than Monkey Shoulder (only other Scotch I've had recently) but not a whole lot more. Again, what causes a rubber note? Thanks!
