Coca-Cola Zero Sugar. That before was simply Coca-Cola Zero, offers without sugar and without calories the classic cola drink, that truly tastes like the original version. The company launched it in 2005 to give all the same taste of the classic Coca-Cola, but without any sugar or calories.
They managed to remove the sugar and corn syrup, replacing them with artificial sweeteners. Even so, here is the difference: it differs from Diet Coca-Cola, that relies on a totally different recipe. Coca-Cola Zero uses the original formula of Coca-Cola as a base and only replaces the sugar with a mix of zero-calorie sweeteners.
Coca-Cola Zero Sugar: Taste Without Sugar
The sweet force comes from aspartame and acesulfame K, that together form a taste surprisingly close to the original. Diet Coca-Cola on the other hand has its own distinct taste profile, because it depends on a different mix of sweeteners. Also, Diet Coca-Cola carries around 35 percent more Caffeine than Coca-Cola Zero Sugar.
Like this although both are without sugar, they are not identical drinks at all.
What is in the recipe? Carbonated water, caramel color, phosphoric acid, aspartame and potassium benzoate for preservation. Because the carbonated water forms the main part of the recipe, you also get natural carbonic acid.
But here is the warning: that acid can slowly wear down the tooth enamel over time. So, although it has zero sugar, the drink stays quite acidic and requires attention to dental care if you drink it often.
Potassium benzoate appears in very small amounts. Talk about less than five parts per billion, that health authorities consider totally safe in normal use. The artificial sweeteners themselves caused a lot of discussion and ongoing research about there long safety.
Even so, in typical amounts of drinking, no danger is shown as serious. That said, moderation always is wise. A normal 12-ounce dose is what most folks see as one serving.
Regular Coca-Cola in that same 12-ounce size carries around 39 grams of sugar. Coke Zero, on the other hand, has about 59 milligrams of aspartame; so only a fraction of the sweet load. It has almost one calorie, but rules about food labeling allow to round it to zero on the packet.
You find Coke Zero in many forms: 500 ml bottles, one-liter, two-liter bottles and various bundles. The packaging also changed, the old almost all-black version gave way to one where red leads with black script. Interestingly, some sugar-free drinks can wake cravings for sugar in certain folks.
Besides the original, Coca-Cola offers also cherry and vanilla versions, plus a version without Caffeine if you prefer that. Water stays the healthiest everyday option, but forthose that cut sugar, Coke Zero gets close to the usual good taste.
