An anonymous reader writes from a report via Ars Technica: Soylent has ventured in a new direction with its latest beverage: breakfast. Called Coffiest, the new offering has the same ingredient makeup, nutritional mix, and 47/33/20 percent fat/carb/protein calorie distribution as the 2.0 premixed version, but it also adds coffee flavoring, 150mg of caffeine per serving, and 75mg of the nootropic L-Theanine. According to Soylent founder Rob Rhinehart, a bottle of Coffiest supplies the drinker with about 400 kilocalories and about 20 percent of the daily recommended values for "all essential vitamins and minerals." "A lot of people are skipping breakfast," Rhinehart told Ars in a phone interview. "We wanted to provide a convenient and also really tasty option for them to enjoy in the morning." Additionally, the company will also be releasing a nutrition bar, called the Soylent Bar. This one will deliver 250 kilocalories per bar, and has a macronutrient breakdown of 38/43/19 percent fat/carb/protein. "Coffee flavor is extremely complex," Rhinehart told Ars. "The direction I gave was a little bit of a more darker, richer roast it's a little darker coffee. A little bit of cocoa powder, just a barely perceptible amount, but it rounds out the flavor nicely." "It was a huge challenge to develop a coffee flavor that would survive processing," he continued. "You can't take any risks with health or safety, so we have to eliminate any sources of contamination from the product and that involves heat. So we had some great food scientists and flavor scientists work out a flavor system that combines natural coffee extracts with an artificial flavor system. And it turned out pretty great." As for the toots, neither Coffiest nor the Soylent Bar will cause consumers to erupt with "horse-killing farts," a complaint made by many of Soylent's customers as well as Ars Technica writer Lee Hutchinson. For those interested in Soylent's latest concoction, Coffiest is available for purchase today at the Soylent site for about $40 for a pack of 12 servings (or $37.05 with a recurring subscription). The Soylent Bar will launch later for about $2 per bar. You can view Coffiest's nutrition facts here.
