Imagine popping a single-serve pod into your Keurig machine and — ta-dah! — out pours a martini.

The idea is not far-fetched. Keurig Green Mountain — the manufacturer of the popular single-cup coffee maker — is now working on an at-home booze machine.

If all goes according to plan, it would be like having a personal bartender in your home, offering everything from single servings of beer and spirits to cocktails and mixers.

For the project, U.S.-based Keurig has teamed up with Anheuser-Busch InBev, a multinational beverage and brewing company.

"We can't wait to get started," says CEO of the joint venture, Nathaniel Davis, in a statement.

There's no word yet on how exactly the machine will work and if customers will have to buy boxes of beer or cocktail pods to make the system work. Keurig's coffee maker requires that customers insert a coffee-filled plastic pod to make one cup.

For now, all that the partnering companies would reveal is that the alcohol drink machine will build on Keurig's Kold technology.

Keurig launched its Kold at-home soda-making machine in late 2015. It was a complete bust with consumers, and in less than a year it was yanked from the market.

When it debuted, Keurig Kold retailed for a whopping $369.99 US, more than double the price of most Keurig coffee makers. A pack of four Coke pods typically cost about $5 US — that's $1.25 per drink.

Critics claimed the machine was ridiculously expensive, slow and less convenient than opening a can of pop.

"As a consumer product, it's baffling," concluded the technology publication Wired in 2015.

"I thought that was a horrible strategy," consumer behaviour expert Robert Carter says about the Kold machine.

He believes an alcohol drink maker will also be a failure. Keurig's single-serve coffee system appeals to consumers because it's more convenient than brewing an entire pot, says Carter, who is with NPD Group in Toronto.

But he points out that people can already buy all sorts of ready-to-drink alcoholic beverages — from craft beers to pre-mixed cocktails — and keep them handy in their fridge.

"I don't think they're solving a problem that exists," says Carter. "They're just creating more work for something that's already convenient."

He believes Keurig is trying to expand its market share because sales of its coffee machines and pods have flat-lined in North America.

But Carter says a better strategy would be for the company to try to grow its hot drink offerings by adding more innovative products such as specialty coffees.

"Stick to what you know," he says.

Keurig isn't the only one trying to cash in on the at-home booze market.

Last year, SodaStream announced a new home beer system, the Beer Bar. According to the Israeli drinks company, the device "enables consumers to concoct crafted beer in seconds" by adding a light beer concentrate called Blondie to sparkling water.

Keurig was bought by the privately held Germany conglomerate JAB Holding in 2015, but is still based in Waterbury, Vt. At the time of the takeover, Keurig was suffering from slowing sales and its stock had fallen nearly 61 per cent since the beginning of the year.
