What's popular in the coffee shop world is always changing. Jumping from locally-sourced ingredients to industrial-looking decor, it can be hard to keep up with what people are into. There are some trends, though, that stick around longer than a couple months or a year, quietly growing in popularity until, before you know it, they're shining at the forefront. The trend of experiential coffee is turning out to be one of those trends. Starbucks recently announced that they will add Reserve coffee bars to up to 1,000 cafe locations, mostly across the United States. Reserve bars are, essentially, the coffee giant's attempt to take on the premium brewing experience that customers have started to demand recently.
