According to the Financial Times, Nestlé will pay up to $US500 million for a 68% stake in the chain, which plans to have 55 locations by the end of the year. There are currently Blue Bottle stores in the Bay Area, Los Angeles, New York City, Washington, DC, and Tokyo.
Blue Bottle has received a total of $US120 million in funding from many big-name investors over the years, from Morgan Stanley, Fidelity Management and Research, and True Ventures, to Bono, Jared Leto, Tony Hawk, and the founders of Twitter and Instagram.
The company has become hugely popular with hipsters and techies from coast to coast. Vintage brewing machines and artisanal coffee are some of its major selling points, and lines are known to get long.
We previously paid a visit to the spacious Blue Bottle cafe in Williamsburg, Brooklyn, to see what the hype is all about.
We visited Blue Bottle's Brooklyn shop, located on a pretty nondescript street in Williamsburg. The cafe is housed in an early 20th-century brick building that, according to Blue Bottle's site, was at different times used by glass blowers, metal smiths, and barrel makers.
We got our first glance of their famous Blue Bottle logo right at the entrance. The logo on a to-go cup is part of the company's cachet and a sure sign the drinker is 'in the know' about what's cool in the world of coffee.
Guests were sipping coffee and reading the newspaper at the counter when we visited in the late morning.
There were a lot of people around, but the cafe was laid-back, and mellow music played over the speakers. We missed the morning rush, when lines can build up.
We snuck a peek at what was going on behind the counter. The company prides itself on unique brewing techniques, and the Williamsburg location uses a vintage Probat roaster, Kyoto-style iced coffee drippers, and a restored Faema Urania lever espresso machine.
Coffee isn't Blue Bottle's only product. You can buy granola in to-go bags or choose from the baked goods in this case behind the counter.
But there's also a lot of gourmet stuff to look at on the counter, including these Mast Brothers chocolate bars, also from Williamsburg.
To start, we decided to try the New Orleans iced coffee and the Buckwheat Buttermilk Biscuit Sandwich.
The biscuit was one of the best coffee-shop pastries we've had, a savoury combination of sweet and salty flavours.
Next we decided to try some espresso (left) and drip coffee (right). Helpful labelling on each package of coffee lets you know what kind of beans are inside, including where they're from and whether they're Fair-Trade certified.
The barista told us that this coffee, which also came from Ethiopia, would best be enjoyed black. It came served hot in a glass mug and had a light floral taste, almost like a tea.
These funky-looking machines are actually slow cold-drip coffee makers from a Japanese company called Oji. They're used to make Blue Bottle's Kyoto iced coffee.
The five globes and filters are situated among a collection of coffee knick-knacks opposite the counter where we ordered.
Sacks of coffee beans sit on shelves in the back. The staff explained that they roast small batches at a time, equivalent to about half of one of these bags.
Every day, they process the beans on this vintage Probat roaster, a very precise procedure that requires a lot of concentration. Beans are served within 48 hours of roasting, which guarantees their freshness.
Small, simple signs with faux handwritten font prohibit smoking in the cafe (and offer a number if you're looking to quit).
