Diet Coke
Diet Coke does not use a modified form of the Coca-Cola recipe, but instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero (replaced by "Coca-Cola Zero Sugar" in 2017), a sugar-free variation of regular Coca-Cola.
Soylent (meal replacement)
Reviews on the taste of powdered Soylent vary. One reviewer said he was "pleasantly surprised" with the "rich, creamy, and strangely satisfying" flavor, and another likened it to that of a vanilla milkshake with the texture of pancake batter. Negative reviewers said it tasted "like someone wrung out a dishtowel into a glass", said "my mouth tastes hot and like old cheese", or that it was "purposefully bland", "vile" and made the taster "gag" and compared the taste to "homemade nontoxic Play-Doh".
