Apples and gooseberries have deep roots in New York—apples have thrived since colonial times, while gooseberries, once restricted due to disease concerns, are now making a quiet comeback. With a crisp snap and tangy bite, they blend orchard sweetness with wild tartness, brightened by the subtle, clean sweetness of birch sap. Together, these flavors create a naturally refreshing seltzer with old-world character and a modern twist.
