For some people, beer is the perfect end to a workday. For Bertha Jimenez, it is the start of a new way to eliminate food waste.
Breweries throw out millions of pounds of used grain every day that could have other uses. While some is repurposed as animal feed, compostable products or heating fuel, little has been exploited for its value as food.
But Jimenez, 35, has created a small startup, Rise Products, that converts the grain into a flour that is finding its way into sustainable bakeries and kitchens in New York and as far away as Italy.
The potential for recycling beer waste first came into the cross hairs of Jimenez, an immigrant from Ecuador, while she was working toward her doctorate in 2015 at the Tandon School of Engineering at New York University. Intent on finding ways to reduce industrial waste, she started a side project with like-minded friends -- most of them also immigrants -- and craft beer provided an easy target: Everyone loved it, but it had issues.
Jimenez lives in Brooklyn, which at last count had 20 craft breweries that are tossing out grain. Jimenez and Ashwin Gopi, a classmate and a founder of Rise, began asking around for samples so they could figure out how best to reuse them.
Gopi called Jeff Lyons, who was then the brewer at Greenpoint Beer & Ale Co. "They told me they were trying to reduce waste," said Lyons, who quickly agreed to supply some grain -- three Tupperware containers' worth, all the students could carry. "The grain still has nutritional value, and all we were doing was throwing it out."
Brewing relies on grains, typically malted barley, which are first soaked in hot water. This step releases sugars that are crucial to the later production of alcohol. Once those sugars are released into the liquid, the grain is discarded.
Knowing that barley was healthful, Gopi, Jimenez and a third founder, Jessica Aguirre, nibbled it plain. Spent grains look and taste like brown rice, without the heft. They stirred the stuff into porridge, and baked it into cookies and cakes. But when they took the dried grain to bakers to gauge their interest, they were met with shrugs.
Finally, Peter Endriss, an owner of the Brooklyn bakery Runner & Stone, suggested they make flour. "It seemed like such a logical repurposing of spent beer grains," he said.
Today, the Rise Products team makes its flour in a commercial kitchen in Long Island City, Queens. The grains are dried in an oven, then ground, milled and sifted into a fine flour -- all by hand, which is why it costs $8 a pound wholesale, and $16 retail. The price will drop, the partners say, when they raise more money, move to a bigger space and automate the process.
But because of the growing interest in reducing waste, many chefs and bakers are already eager to work with what the team is calling its "Super Flour."
At Runner & Stone, Endriss makes a shortbread cookie with a half-and-half blend of Rise flour and all-purpose flour. Bien Cuit, another Brooklyn bakery, has created a chocolate, barley and dulce de leche poundcake with a streusel made of Rise flour. Sfoglini, a Brooklyn pasta maker, produces radiatori using a combination of durum semolina, rye and Rise flour.
Another champion of recycling food waste is the Italian chef Massimo Bottura, whom Jimenez impulsively emailed in 2017 to see if he would like a sample. He did, and later his employees asked for another 15 pounds. There is no word yet what they will do with it, but one day it may appear on the menu at Bottura's restaurant Osteria Francescana in Modena, Italy, which was recently awarded the top spot on the World's 50 Best Restaurants list.
The Rise partners say some big brands also have requested samples, including Kellogg's, Whole Foods and contract manufacturers for Nestle and its subsidiary DiGiorno Pizza. Barilla, the Italian pasta maker, has invested in ReGrained, a small startup in the Bay Area that is making granola bars with brewery leftovers and its own spent-grain flour.
Joel Gamoran, national chef for Sur La Table stores, loved the scent of the Rise flour when he first opened a bag last summer. "It totally has this insane, nutty profile that you don't get from flour," he said. Gamoran talked with Rise about using it in his cooking classes, but until the price comes down, it is just a conversation.
As barley contains less gluten than wheat, it works better with foods that do not need to rise much, like biscuits or bread. Gamoran used the Rise flour for biscotti, crisp shortbread and wafers, which he thought were "400 times better then anything I had put together" in the past.
And because brewing removes sugars, Rise flour has one-third the carbohydrates of traditional all-purpose flour; because it is made from barley, it has twice the protein and 12 times the fiber.
Rise now uses about 1,200 pounds of grain a week, from several craft brewers in Brooklyn; it takes about 4.5 pounds of grain to make 1 pound of flour.
In order to grow, Rise applied to several business accelerators that could provide money and mentorship. In 2016, after Jimenez got her doctorate, Rise joined Food-X, an accelerator in New York City, and completed plans for a mechanical process that could speed flour production. The program connected them to a lawyer who helped them file a patent for the method in 2017.
