I offered my Dad a dram of Yamazaki 18 year old. Which is 2 thirds full, and has been open for about 3 months. When I took the bottle out of it's box it had a collection of bubbles floating on top. When you pour out the whisky there is also bubbles floating in the glass. So unless someone has put a squirt of Fairy liquid in my whisky I don't know what to make of it.
Any comments or ideas as to what has happened will be most welcome. Thanks in advance.
Les.
