Do we know that Wood Elves even make wine?
There are plenty of other alcoholic drinks. They could make cider from fruit or mead from honey.
It has been mentioned in the fluff several times. Although I am sure they make meads and ciders too.
Yeah GotF mentions Wood Elf win a fair few times, as well as it's potency. It's still a good read after about 7/8 years for anyone who doesn't have it.
Awake O Dead, for there can be no rest for ye beneath the earth. Let the splintered bones burrow from the grave pall. Let cold fingers grip time-worn blades, and unseeing eyes survey the fields of slaughter. For your time has come once more. And the dead shall walk.
There is a bit of talk about wine in Caledor which I assume, that knowledge stayed with the elves that Malekith took to the main continent and stayed in Athel Loren; they retained that knowledge and kept up the practice?
There are a couple things in Caledor which touch on grounding elf society so we can relate to it. University talks etc.
