There are more than 20,000 Starbucks around the world, and almost all of them have a familiar menu — tall, grande, and venti drinks of various flavors and varieties, scones and other stuff like that, and the occasional artisanal cheese plate in a plastic container. While the chain is extremely popular in the sixty-plus nations which have at least one store, there are certainly some who prefer a local, more personal touch. For them, Starbucks is hardly the best option. Of course, the mega-coffee company can certainly afford to lose these types as customers — at $13 billion in revenue, what’s a few coffee sales here and there?

In fact, in the summer of 2009, a Starbucks in Seattle — the birthplace of the brand — shut down. In a strange reversal of fortune, in its place popped up a new, mom-and-pop type of coffee joint, one serving not just coffee, but also wine and beer, and with a selection of baked goods from a local bakery. In an interview with PSFK, the new place’s designer said that the “aim was to become a true reflection of the neighborhood.” Even the name echoed the strive to be specific to the area: the former Starbucks, located at 328 15th Avenue East, was simply called “15th Avenue E Coffee and Tea.” And underneath the sign read three more words: “Inspired by Starbucks.”

And owned and operated by Starbucks, for that matter. The new store hadn’t ousted the coffee behemoth. It was the behemoth.

To its credit, Starbucks wasn’t trying to hide this fact — it simply wasn’t trumpeting it. Doing the latter would take away from the test. Starbucks wanted to see if locally-themed (and, therefore, different) unbranded Starbucks could be a viable business. Originally, the plan was to create three of these in the Seattle area, with the long-term intention of creating “Inspired by Starbucks” coffeehouses in cities throughout the country if not the world. One Starbucks exec called these stealth stores “learning environments for us to be creative and push the envelope” outside the barriers of the well-established Starbucks brand. (The company was serious here: one couldn’t even use their Starbucks card at 15th Avenue E.) Some critics didn’t appreciate the stores, though, believing that Starbucks was trying to hide its involvement. Starbucks, of course, denied this; Howard Schultz, the company’s CEO, reportedly claimed that the non-branding (not even the mermaid cups!) was because of the experimental aspect of the store, specifically pointing out that the 15th Avenue E sold wine and beer.

Further, Starbucks claimed (via this New York Times article on the non-branded store), coffee is more local than one would otherwise think: “Coffee drinkers in the Sun Belt, it turns out, prefer cold drinks, while those in the Northeast generally like drip coffee and those in the Pacific Northwest drink more espresso. Yet the executives in charge of regions of the country were divided along time zones and out of touch with what different customers wanted.” By returning to a local-first approach, the company hoped to remedy this flaw.

Did the experiment work? That’s hard to say. In the “no” column: 15th Avenue E reverted to a “normal” Starbucks in February of 2011, roughly 18 months after its initial transformation. In the “yes” column: first, the reborn Starbucks at the location still sold wine and beer. And second, in 2012, another unbranded “stealth Starbucks” emerged in the works, this one in the flagship Macy’s in New York City.

Bonus fact : The core Starbucks sizes are tall, grande, and venti, as noted above. That’s a strange trio, given that a “tall” is therefore a “small,” a “grande” (which is Italian, in this case, for “large”) is the medium size, and the “venti,” which is “twenty” in Italian, the large. What gives? About.com explains the history. Originally, there were two sizes, “short” (small) and “tall” (large). “Grande” joined after, becoming the new “large” and moving “tall” to “medium,” which was still descriptively true. But over time, the “short” fell off the menu — you can still order it, it’s just not listed — and then, “venti” joined, giving us two arguably incorrect labels. As for the “venti,” it’s 20 fluid ounces — except for iced venti drinks, which are 24 ounces, but we’ll give that one a pass. (And now there’s the “trenta,” which at 916 ml or about 31 ounces, is larger than the average human stomach.)
