So I have this JW Blue Label King George V bottle sitting in my bar for around 5 years and I decided that tomorrow would be a good day to finally open it (new year´s eve) but today I grabbed it to clean the dust out of it and I found a nasty surprise, there is some sediment at the very bottom and if you move it around a little it floats all over the place, the bottle is sealed just like new I don´t know why this happened, it´s not a lot of sediment but I don´t know if it will affect the taste or if it is even drinkable.
I´m kind of new to whiskies and I don´t know if maybe this is something normal?
I havn´t even opened it hoping that maybe there is some guarantee or something
Should I drink it?
I attached a picture of the bottom of the bottle
