Pine needle vinegar is quite a different story. Subtract sweetness for acidity; the Pine notes are still there, but the results are far more interesting. It's pretty simple to make too.
Scots Pine needle vinegar
Cider or white wine vinegar
A bag of Scots Pine boughs
Remove the pine needles from the boughs and wash. Bring the vinegar to the boil, then allow to cool for a short while. While it's cooling, fill a sterilized bottle with Scots pine needles, then pour in the warm vinegar. Leave in a dark spot for about two months before using.
