I've never cared for any kind of alcohol I've tasted until I started culinary school, and had some strawberry shortcakes made with Grand Mariner. So far, it's still the only stuff I can tolerate (okay, adore) the taste of, and I've been looking into getting a bottle to experiment with at home.
I've already seen how expensive the stuff is, and so I was looking into getting one of the 750s I found for $30 (I think that's a good price?), but given that most home-scaled formulas call for 10-15mL, and I won't be drinking it, I know I'll have it on hand for a good long while. This presents a problem, as I know next to nothing about how to store it; does it need to be refrigerated after opening? How long will it keep after opening?
Any general advice or things that an ignorant alcohater should know?
