Sour candy has an arms race problem: every brand claims to be the sourest, and most are lying. Sour Tooth built its entire identity on the claim, right down to the slogan, “There Is No Sour Like Ours.” This video works through 10 of their flavours in one sitting, which is either a taste test or an endurance event depending on how your tongue feels about citric acid.
Watch the video above for the flavour-by-flavour reactions, then read on for the background on the brand and what makes its candy hit differently.
Meet Sour Tooth
Sour Tooth is a gummy candy brand built around one idea: a heavy sour sugar coating over a soft gummy base. The candy is made in Spain, a country with a serious gummy tradition, and packaged in the USA. The lineup covers the classic sour formats: sour belts, sour rings, sour fruit shapes, and sour twin cherries, sold in bags and multi-packs on Amazon and through candy retailers.
On the label side, the range is fat free, gluten free, and dairy free, which removes the usual candy-aisle exclusions for a lot of snackers. The texture is the other half of the formula: these are soft gummies, not the jaw-working kind, so the sour coating is the whole event rather than a warm-up act for a chewing marathon.
Why the sour lands harder
Sour candy gets its punch from food acids, mainly citric acid with malic acid doing the longer-lasting work. Coated candies like these put the acid on the outside, in the sugar crystals, so the first second is maximum sour before the sweet gummy underneath takes over. That sequence, blast first and sweetness second, is why coated sour gummies taste more extreme than candies with the acid mixed through the body.
It also explains why a 10-flavour session compounds. Acid fatigue is real: your palate’s sensitivity drops as the session goes on, which reviewers of sour candy call going “sour blind.” The flavours late in a taste test have to work harder, and the ones that still register at number nine or ten are the strong ones. Watching where a taster’s reactions fade is genuinely useful data if you are choosing a bag.
The formats, ranked by mess and intensity
Belts are the spectacle format: wide, flat, and coated on every millimetre, so they deliver the most coating per bite. Rings (the peach-ring style) balance coating against a thicker gummy chew, which stretches the flavour out. Fruit shapes and twin cherries are the snackable end of the range: smaller pieces, easier pacing, and the natural pick for a movie or a road trip where a belt per bite is more commitment than the moment wants.
If you are buying one bag to test the brand’s claim, the belts are the honest benchmark. If you are buying for a group, the assorted multi-packs with mixed shapes are the crowd-pleaser format, and they are how the brand is usually sold online.
How to run your own taste test
If you want to replicate the experiment, order matters. Start with the mildest format you have and finish with the belts, not the other way around, or everything after the belts will taste like sugar water. Keep water nearby and use it between flavours: it resets your palate better than pushing through, and it slows the acid down. Give each flavour two pieces, because the first is all coating shock and the second is where the actual fruit flavour shows up. And space a serious session out. Ten flavours back to back is entertaining on camera; your tongue will file a complaint either way, but it complains less with breaks.
Canadian buyers will find the brand on Amazon with assorted bags and multi-packs, and the pricing usually lands in line with premium gummy brands rather than bulk-bin candy, which matches the specialist positioning.

Where is Sour Tooth candy made? The gummies are made in Spain and packaged in the USA, and they are sold through Amazon and candy retailers in bags and multi-packs.
How sour is it compared to regular sour gummies? The brand’s whole positioning is an extra-heavy sour coating, and the taste test format shows it: the coating delivers the sour up front, before the sweet gummy base. If standard grocery-store sour candy tastes mild to you, this is the step up.

Verdict
Sour Tooth is a specialist brand doing one thing at full volume, and the 10-flavour test shows both the appeal and the limit: the coating-first formula delivers a genuinely aggressive sour that most mainstream candy only advertises, and a full session will test anyone’s palate. For sour fans, that is not a warning. That is the review.
