did i finish expensive gin?

house sitting for my grandparents and they’re so sweet and loving i couldn’t ask for better ones. they said me and my bf are welcome to anything in the pantry including alcohol (we are both of legal age) i’ve been drinking this gin and the whole time im like wow this looks like an old bottle! they have a bunch of old alcohol but my grandma ONLY drinks wine and my grandpa doesn’t drink at all so i wonder if it’s old. didn’t realize i finished it and now im a bit worried it was expensive. cant find a specific answer on if this one is special or not. im sorry if this isn’t allowed please forgive my anxiety as well 🥹
