birch beer from scratch recipe? soda, not beer

ive been looking for a birch beer soda recipe, but im mostly finding recipes for a beer, not a soda. any help?

There's really not much to soda - mix sugar, water and extract, add hydrated yeast and bottle. Check out the pdfs with these, each has a recipe

and there's this

are you looking for is someone's birch beer recipe. From what I've looked at out there, there doesn't seem to be too much involved. I've done some looking around and they all say that it needs a good birch oil (distilled birch sap) and that the birch oil's flavor and color depend on the type of birch tree its from. I haven't seen any other ingredients involved (other than sugar and water).

Here's someone who tried wintergreen and the bark. They seem to say that they'd rather try the oil to get more flavor. http://ironoakfarm.blogspot.com/2010/01/birch-beer-experiment.html

andif using oil, how then would you make it?
