Can anyone give information

I gave my sister this bottle as a gift about 8 years ago. It was given to me because I worked at someone’s place on a weekend (construction) the lady of the house told me her husband bought a full pallet of them because they where discontinued. I told my sister that and she has not opened it because she loves that she may be one of the only people to have a fully sealed unopened bottle. But can anyone say the value or if you’ve had it and it was any good?
