Is there such thing as "expired date" of alcoholic drink after the bottle has been opened? I have couple of small bottles of vodka, cognac, and pastis, which I used to have experiment with food long time ago. Making lobster sauce was one of them. But, again, that was quite long time ago, almost 5 years, and since then I have never touched it. I store them in dry cool cupboard without any kind of special or whatnot, just let them stand there Note that I don't drink alcohol because I will easily get headache Use it for making sauce is ok. Thanks.
