I bought watkins rootbeer extract that is natural flavors, Zatarain's, and Shanks. All 3 were good. Shanks tastes more like rootbeer soda than Zatarain's. Watkins rootbeer extract blew them both out of the water. It's about 3-4x more potent than both of them, natural flavors, and to me it tastes more like actual rootbeer than the other two. On top of that, when you calculate the potency, it's actually cheaper than Zatarains and Shanks. As an added bonus, Watkins is clear so there are no colorings or other unhealthy ingredients like the other two.
My wife and I buy club soda from the store, put a dash of pure stevia powder bought on Amazon, and use this extract and it tastes just like the Zevia rootbeer you buy from Walmart. Delicious.
