Sodas with no artificial sweeteners are the ones sweetened only with sugar, cane sugar, invert sugar, corn syrup, honey, or fruit juice. If the ingredient list does not contain aspartame, sucralose, acesulfame potassium, or saccharin, you are holding one. The ingredient list settles it, not the front of the can.
The four names to scan for
Artificial sweeteners are a short, specific list, and in soda you will almost only ever meet four of them:
- Aspartame (sometimes listed as NutraSweet or Equal). The classic diet soda sweetener.
- Sucralose (Splenda). Common in zero-sugar sodas and sports drinks.
- Acesulfame potassium, usually written as Ace-K. Almost always blended with one of the others to round out the taste.
- Saccharin (Sweet'N Low). Rarer now, still turns up in older formulas and store brands.
Find none of those four and the soda has no artificial sweeteners. That is the whole test.
Where it gets muddy: stevia and monk fruit
Here is the part that trips people up. Stevia and monk fruit are plant-derived, so they are not classified as artificial sweeteners, and a can sweetened with stevia can legally say no artificial sweeteners on the front. That is accurate labeling.
But plenty of people searching for this are not really asking a regulatory question. They are asking for a soda that does not have the particular taste that high-intensity sweeteners leave behind, the thing people describe as a twang, a cooling edge, or a finish that lingers a beat too long. Stevia and monk fruit are hundreds of times sweeter than sugar, and at that concentration they behave differently on the tongue than sugar does.
So there are really two questions hiding in one search:
- No artificial sweeteners rules out aspartame, sucralose, Ace-K, and saccharin.
- No high-intensity sweeteners at all also rules out stevia and monk fruit, leaving only sugar-family sweeteners and fruit.
If it is the taste you are chasing rather than the ingredient category, the second list is the one you want.
What sweetens what
As listed on labels in 2026. Recipes get reformulated, so check the current can.
| Soda | Sweetened with | Artificial? | High-intensity? |
|---|---|---|---|
| Coca-Cola (US) | High fructose corn syrup | No | No |
| Coca-Cola (imported, cane) | Cane sugar | No | No |
| Diet Coke | Aspartame | Yes | Yes |
| Coke Zero Sugar | Aspartame and Ace-K | Yes | Yes |
| Sprite Zero Sugar | Aspartame and Ace-K | Yes | Yes |
| Zevia | Stevia | No | Yes |
| Olipop | Cane sugar and stevia | No | Yes |
| Poppi | Cane sugar and stevia | No | Yes |
| Virgil's (full sugar) | Cane sugar | No | No |
| Spindrift | Fruit juice only | No | No |
| Reckon | Invert sugar | No | No |
The pattern worth noticing: almost everything in the modern low-sugar aisle solves the sugar problem by adding a high-intensity sweetener. Very few solve it by simply using less sugar.
Reading the panel in ten seconds
Ignore the front of the can entirely. Turn it around and read the ingredient list bottom to top, because sweeteners are used in small amounts and cluster near the end. Scan for the four artificial names, then for stevia, stevia leaf extract, rebaudioside A, Reb A, monk fruit, or luo han guo. Whatever you do not find is not in there.
One more cross-check: compare the sugar grams to the calories. A soda with real sugar and low calories has genuinely less sugar in it. A soda with near-zero calories and a sweet taste is getting that sweetness from somewhere other than sugar, and the ingredient list will tell you where. Our full walkthrough is in how to read a soda label.
What Reckon uses, plainly
Reckon is a tart craft soda sweetened with invert sugar and nothing else. No aspartame, no sucralose, no acesulfame potassium, no saccharin, no stevia, no monk fruit. No artificial colors either, since the tart cherry gets its red from black carrot and the apricot gets its orange from beta-carotene.
Invert sugar is sugar that has been split into its two simpler parts, which is why it reads smoother and rounder than granulated sugar at the same level. That is what lets the recipe run at 90 calories and 15 g of sugar for Cherry, 80 calories and 12 g for Apricot, less than half the sugar of a typical cola, without reaching for a high-intensity sweetener to fill the gap. More on that in what is invert sugar.
One thing to note before you buy: Reckon contains wheat by way of barley malt, so it is not gluten-free. Every ingredient, calorie, and allergen fact is on our brand facts page. It ships as a 12-pack, with a subscribe and save 10% option every four weeks.
Not too sweet. On purpose.
Frequently asked questions
Which sodas have no artificial sweeteners?
Any soda sweetened only with sugar, cane sugar, invert sugar, corn syrup, honey, or fruit juice. That includes regular Coca-Cola, Virgil's, Spindrift, and Reckon. Diet and zero-sugar sodas almost always use aspartame, sucralose, or acesulfame potassium.
Is stevia an artificial sweetener?
No. Stevia is derived from a plant, so a soda sweetened with it can accurately say it has no artificial sweeteners. It is still a high-intensity sweetener, hundreds of times sweeter than sugar, which is why some people notice a different finish.
Does no artificial sweeteners mean low sugar?
No. The two are separate facts. A full-sugar cola has no artificial sweeteners and about 39 g of sugar. Check the nutrition panel for the sugar number and the ingredient list for the sweetener type.
What sweetens Reckon?
Invert sugar only. No aspartame, sucralose, acesulfame potassium, saccharin, stevia, or monk fruit. Cherry is 90 calories and 15 g of sugar, Apricot is 80 calories and 12 g.
