Allie, that is a tough decision.
Elderflower wine is great during summer.
Last year i made 10 liter (about 3 gallon) and I knew immediately that it would not last that summer.
That is why I made 60 liter this year.
It is an early drinker.
But then.............
I make about an equal amount of elderberry wine each autumn.
That is a great winter wine. I make it port-style heave in the alcohol and a lot residual sugar.
Luckily they are all over the place here. So I do not have to make that decision. There are at least a hundred large elderberry plants here in the near environment. Each year there are far more as I can pick.
Tom:
I have not yet tried to dry them, but next year I might.
Maybe someone in the US could send you some dried ones. Shipping from here would be outrages expensive.
