(Bloomberg) -- In recent years, alternative sources of milk have begun to disrupt the dairy industry, from soy to almond to rice. The latest contender for space in your refrigerator is milk made from yellow peas.
But there are barriers to mainstream adoption: Soy milk can taste chalky, and soy beans are notorious for being genetically modified. Almond milk, despite its high-protein reputation, has only one-eighth the protein of dairy milk and requires huge amounts of water to produce. Rice milk has a pleasant enough flavor but is also low in protein.
Enter Ripple, a new line of dairy products powered by $44 million from Google and Silicon Valley venture capitalists. Since it launched in April 2016, the company has sold 2.5 million bottles of product and generated $20 million in revenue, using milk made from simple yellow peas. The vegetable is inexpensive to grow and also produces a surprisingly clean taste.
The duo behind this plant-based milk is a formidable team. Adam Lowry is a co-founder of eco-minded cleaning line Method, which generated revenue of more than $100 million when he sold it to Ecover, a Belgian company, in 2012. Neil Renninger helped build Amyris Biotechnologies, which uses technology to create renewable fuels, which started with a grant from the Gates Foundation; he has also been an entrepreneur-in-residence at the Menlo Park VC firm, Khosla Ventures.
In 2014, the two friends saw an opportunity to change the dairy industry. “The food system represents 20 percent of the world’s carbon emissions, and dairy is one-quarter of that,” said Renninger via telephone. “The impact is massive. More than beef, more than chicken, dairy is actually the largest contributor to emissions by volume. That challenge scratched my sustainability itch.”
Lowry and Renninger began searching for a product that would simultaneously taste better and be more eco-friendly than existing alternate milks. They maintain that food businesses don’t spend a lot of money on research and developmemt to create better products. “Their idea of innovation is a brand extension,” said Renninger. “We saw huge potential for impact—a lot of white space in the world of food innovation through technology.”
“What we did is use technology to create really good food,” reported Lowry. “The world has recognized that we need to go more plant-based. You see it in the burger world with products like the [meatless] Impossible Burger. But most plant food sucks, particularly in the alternate dairy space. It’s low in protein, thin, and chalky.”
Using Renninger’s technology, they began to experiment extracting protein from from different plants that had a notable amount of the biomolecules. “You name it, we screened it,” says Renninger. Most of them tasted terrible.
Then the pair tried yellow peas, which are inexpensive to grow and don’t yield a strongly flavored product. The result was a drink that has a hint of concentrated powdered milk taste and a smooth, creamy texture.
“It’s not that we have the only pea milk on the market; what makes us unique is that, thanks to technology, we have the purest plant protein in the world,” says Renninger.
The milk made from yellow peas also delivers the same amount of protein as those from cows (8 grams per serving, comparable to soy milk but much higher than almond milk). But what really sets Ripple apart from other alternative milks is its eco footprint.
According to their research, each 48-ounce bottle of Ripple (made from 100 percent post-consumer recycled material) represents a savings of 3.5 pounds of carbon dioxide emissions and 925 gallons of water, versus dairy milk. The 2.5 million bottles Ripple has sold adds up to nearly 7 million fewer pounds of CO2 emissions—the equivalent of taking more than 600 cars off the road for a year. And getting the same amount of protein from almond milk would require 66 billion gallons of additional water.
Currently, five kinds of Ripple milk are on sale at such places as Whole Foods and Target Corp. stores: Original unsweetened milk is the best seller, along with flavors like chocolate milk and vanilla milk, plus half-and-half and kids’ packs. Meanwhile, Ripple is expanding its product base: This winter, the brand will enter the burgeoning yogurt business with a plant-based, Greek style yogurt.
The flavors will range from vanilla to blueberry and strawberry—“plus some dessert-oriented flavors,” added Lowry. “We’re playing with flavors like maple and key lime.” Yogurt is a logical step for Ripple, putting it solidly in the snack category. “Only 14 percent of people who buy non-dairy milk are lactose intolerant. Most consumers do it to be greener. That trend is only going to get bigger,” said Renninger.
And though the toughest challenge is still getting people to try it, the cost of yellow-pea milk may currently be too much for cost-conscious consumers to ignore. (At $5.99, a quart is about a dollar more expensive than soy milk and about 30 percent pricier than organic dairy milk). But Renninger is looking into the future. “In a couple years, we’ll be able to make liquid milk for less than the cost of milk,” he said.
