im sorry, "Oak aGed Gin?"
gilbeys it is

Mixed regular gin with a good splash of oak aged akvavit for the base. Pretty happy with the result. Orange wheel garnish.

How different is the aged gin from regular London dry, and to what extent will it detract from the final result in its absence? Alternatives?

Yum, at least with the bergamot twist to top it off. I’ll have to try it without to see if it holds up without having fresh bergamot around the house. A lovely citrus known mostly as the flavor in Earl Gray tea and as far as I can tell, pretty much obtainable in most of the world unless you have a tree in your yard.

If you are fortunate enough to have access to bergamots, they make a marmalade to die for.
