Birch has sap at 100 to one of syrup. It has a spearmint taste, great for cooking flavours not so good at pancakes or waffles. A brand called Boylan makes a birch beer soda if you want to try it.
If doing bulk birch use a reverse osmosis water treating system, keep the waste water to condense the drinkable water side is just that water lol faster than boiling off 100 l to get one. It also can’t be kept in partial state like maple which is a 25 to one ratio. Birch goes bad after 2 days turn whiteish with floaties.
The splyes (taps) get stain less ones you can reuse instead of plastic. Birch need to be over 12 inched diameter and can only be tapped 2 years then needs a rest or it can die. You can not tap any birch with a fungal infection, the sply holes are sources for contaminations. On plus side it can grow chaga or a strop mushroom for blade shaping, but it kills the tree.
