Better than bouillon liquid storage

I am not trying to reinvent the wheel here, but the whole reason I got on the BTB train was because of ATK and so I could add the water myself. I love the flavor but having to boil water to dissolve it is kind of a pain for a recipe. So my thought was to have the base, but also makeup like a quart of liquid so I can use it straight from the fridge.

Does anyone else use this method and have you had a batch go rancid on you?
