Sediment and floaters. Are they safe?
New member here, have some questions on some old half full whiskey bottles. I'm 39 and I'm sure at least 2 are older than I am. They have been stored in the basement of my parents house in the rec-room at the bar. One is a bottle of Jim beam in a metal holder that says aged 8 years ( been there as long as I can remember so I'm guessing it was bought in the late 60's very early 70's ).The second is a bottle of old granddad the bottle has a 2 and a 69 on the bottom below "liquor bottle". The beam has a cork and has blackish sediment in the bottom of the bottle. The granddad has a glass top that fills when the bottle is turned over. It has a few floaters in it. The last is a half full bottle of old Thompson that has a bar style measured pour tip or what ever they are called on it and it has like a layer of dust it looks like on the top of the liquid. Any ideas as to what causes this and are they still safe to enjoy?
Thanks a lot for the help.
