"Glow" sounds like it should mean glow-in-the-dark. It doesn't — but the name still tells you something true about what's in the bag.
Where the name actually comes from
Glow Worms don't glow under normal light or in the dark — the name is about colour intensity, not luminescence. Trolli's worms come in bright, saturated, almost fluorescent-looking shades, and "glow" is simply the branding shorthand for that look rather than a literal product claim.
Six flavours, two-toned
Our Trolli Sour Glow Worms Bags 150g run through six mixed fruity flavours, with each worm split into two colours along its length — the same two-tone trick used across the wider gummy-worm category to flag a flavour pairing before you've even tasted it. The sour coating hits first, then settles into the fruit flavour underneath.
The Flavorbomb version takes it further
For a more dramatic version of the same idea, Trolli Flavorbomb Sour Glowworms Tub (60 pieces) builds in a sour-then-sweet switch within each piece, rather than keeping the sourness and sweetness constant throughout. Same long, chewy worm format, with the flavour journey doing more of the work.
Worth knowing before you buy
Both lines contain gelatine and carmine, an insect-derived red colouring, so neither is suitable for vegetarians or vegans. Always check the current pack for confirmed ingredients.
