How are bitters with plain seltzer? I have a sodastream and am looking for some good flavors. Can't figure out anything that tastes as good as flavored bubly or lacroix and that doesn't have lots of sugar.
Fee Brothers sells a 12 piece variety pack which is a great way to experiment. After that you have quite a rabbit hole of bitters brands and flavors to explore!
That said I also like plain seltzer and bitter flavors generally (dark chocolate, black coffee, IPAs), so YMMV.
