Någon som kan något om dricka?

Fick idag en fråga:

I hope that you can help me out. Today at our Thanksgiving dinner I was asking my Nana about any traditions she remembered growing up with. My Nana is Swedish, and she started describing a drink they would have as children every Christmas eve and New Years eve. She said that her Grandma called the drink "Dricka" and that it was something her Grandma made in a big vat using yeast and some type of evergreen berry. She also said she used root-beer extract and hops.

Immediately I thought "BEER" :) which peaked my interest. She said her grandma was the only one who could make it and has been missing it ever since she was a child. What made me think it was some type of alcohol was that she said they always were pretty silly after drinking the "Dricka". She also described seeing the yeast working, which made me think of a top fermented beer. It would mean so much to her if I could reproduce this here over the holiday time. Is what she was describing the same beer the farmers on the island made? Is this made with root-beer extract?

I have the equipment to home-brew, so I am very anxious to dive in and try to make this, but I have no recipe. Any help would be so greatly appreciated.

Jag vet inget om hembryggning eller vad han i stort pratar om. Svagdricka? Finsk glögg? Bären måste väl vara enbär? Jag hänvisade till Svenska Hembryggareföreningen, men det kanske är någon här som kan hjälpa denne amerikan. Jag kan i så fall vidarebefordra kontakter.
