Valved can for texturized coffee is a first

Pairing a new valved-can technology with packaging machinery inspired by the aerosol industry, coffee company La Colombe pioneers an authentic draft latte for the RTD market.

Todd Carmichael, president of La Colombe coffee, is a successful entrepreneur, a TV personality, a world adventurer, and a bit of a mad scientist. Carmichael’s enthusiasm is palpable as he works to democratize coffee and bring innovation to the category. His latest invention: a new ready-to-drink, nitrous oxide-infused Draft Latte that not only is the first texturized coffee product, but also boasts a surfeit of packaging firsts.

For one, La Colombe is the first to put a hole in a beverage can—on purpose. Also a first for coffee is the can’s glossy sleeve label and custom-designed “sip-through lip guard.” La Colombe is also the first coffee company to own its own dairy production facility, and its packaging equipment—much of which is from well-known suppliers—has been re-engineered specifically for the product. La Colombe is also most likely the first coffee company to use a gasser shaker, a machine typically used in aerosol filling. And, the Draft Latte is the first nitrous oxide-infused beverage packaged in a can with a hole to go through the retort process.

Carmichael, who began La Colombe in May 1994 with partner JP Iberti, has visited nearly half the world’s countries, has crossed large parts of the Sahara, Gobi, Namib, and other deserts on foot, and is the first American to solo trek across Antarctica from the coast to the South Pole, establishing a world-record speed in the process. Even so, Carmichael admits that creating the Draft Latte was one of the most difficult challenges he’s faced.

“It was hard to convince professionals that a product in a package like this was possible. They looked at me like I was a crazy person,” Carmichael says. “So, the biggest hurdles were pretty much every R&D department I encountered.”

Liberating crafted coffee from the coffee bar

Carmichael and Iberti began La Colombe with the premise that “America Deserves Better Coffee.” To achieve this, they focused on responsibly sourcing their coffee beans and roasting them with care, and borrowing on ancient and modern coffee traditions from around the world. They progressed from operating cafes—they have nearly 30 nationwide now—to supplying the hospitality industry, and now to retail.

La Colombe began innovating around cold coffee in 2009 when they saw it was becoming a big trend in cafes. “Then I realized that was just the beginning,” says Carmichael. “If you’re going to go cold, you’ve got to have the whole menu,” meaning cold espresso and cold latte cappuccino drinks. With the popularity of La Colombe’s on-tap cold latte at its cafes, Carmichael began brainstorming about how to create the frothed milk and cold-pressed espresso beverage in an RTD format, while preserving its taste and texture, to make the premium-quality beverage more mobile.

“The winds are always moving from anchor to mobile,” he says. “Twenty years ago, you would stand in line to cash a check, right? But you don’t do that anymore. But we stand in line twice a day to get our coffee. At La Colombe, we felt we needed to look critically at our processes and our packaging to liberate crafted coffee from the coffee bar. Now, I say that, even though we have almost 30 cafes, and we’re building a dozen more. But they are not going away, just like bars didn’t go away when we learned how to put beer in a bottle, because it’s such a social experience. But now I can have access to beer in my fridge at any time.”

When Carmichael began looking in earnest at creating an RTD latte product in 2014, there were some RTD nitro-coffee products on the market. But using nitrogen was not going to give Carmichael the results he wanted. “You force the nitrogen into the fluid, and then when you open the can, it rushes out,” he says. “It wants to go back into space. It’s an effect; it doesn’t have any substance to it. It’s a novelty for a couple of reasons. It doesn’t alter the flavor. It’s temporary—it’s all over with in about 10 seconds. And ultimately, people don’t drink cold coffee from the top; they drink it from the bottom. You have a lid and a straw. It’s how people drink.”

In order for Carmichael to put the La Colombe name on the product, the beverage had to deliver on its promise: a texturized coffee drink with the same taste and froth as the one consumers could buy at a La Colombe café. To achieve the texture, Carmichael came up with the idea of dosing the beverage with nitrous oxide—a gas commonly used for whipped cream—through the bottom of the can, and then shaking the can to disperse the gas throughout the coffee. For the taste, La Colombe uses the highest-quality, real ingredients, including fresh milk, rather than powdered or rehydrated milk, and cold-press espresso. The drink also packs a full-on caffeine punch, with 115 mg of natural caffeine, equal to one and a half cups of coffee. There are four varieties available: Latte, Triple Latte, Vanilla, and Mocha.

New can manufacturing process

At the start of the project, La Colombe made its own cans, taking a can body, punching a proprietary-shaped hole in the bottom, flipping it, and inserting a grommet. Having this prototype, Carmichael says, helped him convince suppliers that it could be done. “What I was asking these people to do is something they’ve been trying to avoid since the start of their company, and that is, put a hole in the can,” he says. “And it can’t be any old hole.”

In 2015, Carmichael approached Crown about the project. Explains Dr. Daniel Abramowicz, Executive Vice President Technology & Regulatory Affairs for Crown Holdings, “Todd came to Crown because he envisioned the Draft Latte marrying aerosol can and beverage can technology, and Crown has expertise in both markets. We were bullish about the concept and our ability to deliver what was needed. And when we tasted the product, we were ‘in.’”

The process of inserting a grommet or valve in the bottom of a can was not new. However, it had only been done with three-piece aerosol cans, with the valve inserted into the flat bottom component of the can. For the Draft Latte, Crown needed to use a two-piece beverage can with an integrated one-piece can body and a domed can bottom.

“One challenge was effectively piercing and inserting the grommet into a fully formed beverage can compared to the relatively flat bottom component of the three-piece aerosol can,” Dr. Abramowicz explains. To accomplish this involved the design of a new can manufacturing process and new equipment.

The result is a proprietary design with a one-way valve called the InnoValve® can. The chimney-like valve allows the nitrous oxide to be injected into the bottom of the can, while ensuring the integrity of the coffee beverage. When the gas is injected, it dissolves into the milk fats in the latte the same way it does in whipped cream. Explains Dr. Abramowicz, “When the consumer opens the package and releases the pressure in the container, the gas generates the creamy texture that defines these products.”
