Frequently Asked Questions
Sour Candy Brands & Products
Q: What is the sourest candy at Candycopia?
A: Barnett’s Mega Sours are widely considered the world’s sourest candy — roughly three times more sour than Toxic Waste or Warheads. Each oversized British hard candy is loaded with a citric and malic acid coating designed to push taste buds to the edge. The sour challenge at the Oak Park store has become an annual tradition.
Q: What is Mr Simms Black Death Ultra Sour?
A: A British-made extreme sour candy with a cult following on TikTok. Coal-black lemon drops with one of the highest acid concentrations in the sour candy market. It’s consistently one of the most-visited products in the Candycopia online store and a top seller in the Oak Park shop.
Q: Do you carry Toxic Waste candy?
A: Yes. Toxic Waste Nuclear Fusion, and classic Toxic Waste barrels are available. Toxic Waste is known for its #ToxicChallenge, which dares people to hold the sour candy on their tongue for 60+ seconds. It’s a staple of the Candycopia sour collection.
Q: What are Barnett’s Zombie Bombs?
A: Barnett’s Zombie Bombs combine mega sour and mega spicy in the same candy. The initial hit is intensely sour, followed by a building spicy burn. They’re made in the UK using the same craft process as the classic Mega Sours. A unique option for customers who want both heat and pucker.
Q: What sour gummy brands do you stock?
A: BUBS Swedish sour gummies, Albanese sour belts, and sour worms, Toxic Waste, Sour Patch Kids, Barnett’s Mega Sour flavors, and a rotating selection of imported and domestic sour gummies. The gummy mix builder lets you pick from dozens of sour candy gummy options.
Dietary & Safety
Q: Is sour candy vegan?
A: Several sour candy options are vegan, including BUBS Swedish sour gummies, which are made without gelatin, palm oil, or artificial dyes. Sour belts and certain hard candies are also vegan. Each product page lists full ingredient and allergen details.
Q: Is sour candy gluten-free?
A: Many sour candies are naturally gluten-free. BUBS Swedish sour gummies, Barnett’s Mega Sours, and most sour hard candies contain no wheat or gluten ingredients.
Q: Is extreme sour candy safe to eat?
A: Extreme sour candy is safe in moderation. The high citric acid content can irritate the tongue and mouth if consumed in large quantities. Barnett’s includes a consumer advisory recommending starting with one piece. The sour sensation fades within 30 seconds and gives way to a sweet finish.
Q: Can kids eat sour candy?
A: Mild and medium sour candies are fine for most children. Extreme sour products like Barnett’s Mega Sours and Black Death are better suited for kids 8+and adults. The Candycopia team can help parents choose age-appropriate sour options.
Q: Does sour candy damage teeth?
A: The citric acid in sour candy can temporarily soften tooth enamel. Dentists recommend waiting 30 minutes before brushing after eating sour candy. Drinking water and chewing sugar-free gum can help neutralize acid. Moderation and good oral hygiene are the simplest precautions.
Sour Intensity & Types
Q: What’s the difference between mild, medium, and extreme sour candy?
A: Mild sour candy uses light citric acid for a gentle tang — Swedish sour gummies and sour belts fall here. Medium sour includes products like Toxic Waste and sour Warheads. Extreme sour covers Barnett’s Mega Sours and Mr Simms Black Death, which use concentrated acid blends that deliver intense pucker for 10–30 seconds before fading to sweet.
Q: What makes sour candy sour?
A: Citric acid and malic acid are the two main ingredients that create the sour sensation. Extreme sour candies layer these acids into a concentrated coating that dissolves on contact with the tongue. The form, concentration, and blend of these acids determine how intense the sour hit feels and how long it lasts.
Q: Do you have sour candy that’s NOT extreme?
A: Plenty. Swedish sour gummies from BUBS offer a gentle, balanced sourness with natural fruit flavors. Sour belts, sour worms, and retro sour tins are all on the milder side. The team can recommend options for customers who want tang without the extreme pucker.
Q: What is freeze-dried sour candy?
A: Freeze-drying transforms chewy sour candy into a light, airy, crunchy texture with intensified sour and fruit flavors. It’s been one of the biggest candy trends over the past two years. Candycopia carries freeze-dried versions of classic sour gummies and sour belts.
Q: What is the Candycopia Sour Candy Challenge
A: We create a flight of 5-6 sour candies that range from tart to the world's most sour candy to see if you can pucker your way through an entire flight of sour candy. Each year we feature a mix of classic sour candies with new trending and international candies.

Candycopia opened in June 2022 when Patrick and Alycia Mason brought their vision of a discovery-driven candy store to Oak Park’s Hemingway District. Inspired by old-fashioned candy shops on Cape Cod, the Masons built a space where 100+ apothecary jars line the gummy bar, small-batch makers from across the country share shelf space with Swedish imports, and every visit feels like an experience — not just a transaction.
