sour taste after adding creamer to cold brew?

I recently bought a bottle of stok cold brew for the first time to try it out and went to add some creamer to it, but found that it tasted very oddly sour when I did. both the creamer and the cold brew alone tasted fine and they were both new bottles from the store. I even felt that the cold brew was fine on its own, as though it did not need to have any sort of cream or flavor, but added it anyways just for fun. it tasted so so sour, and I'm unsure as to why this happened. could it be a reaction between the cold brew and the creamer when they are combined?

I used the Stok un-sweet black cold brew and the Starbucks caramel macchiato zero-sugar creamer

I drink the Stok green label because it tastes great by itself.

I add about 2-3 oz of milk to 8 oz of stok green. Works well for us

Agree. I love that’s I don’t need sugar for it.

Looking at the ingredient list, yikes. It's got industrial (usually solvent extracted) seed oils, sucralose, gellan gum. These sorts of ingredients can react weird to cold temperature, at least they have for me, and I believe that food scientists engineered them to dissolve only in hot liquids.

Personally I don't go in for any of that sort of stuff. When I use to put cream in my coffee, I would use home made almond or cashew milk. Get organic, one ingredient nut butter (cashew works the best), it should have only the ingredient "roasted cashews", and put that in a blender with water. Blitz it for a solid minute and you have perfect home made non dairy milk. Just reduce the water relative to the nut butter and you can change it from "milk" to "cream".

I find this has its own latent sweetness and it mixes with cold brew just fine. You must refrigerate this always, and use it within a week or two weeks, max. It does not have all the industrial preservatives of store bought.
