Sour Gush Geek Bar

The closest reference is a fruit-burst sour candy — the kind with a sour shell, a sweet liquid or chewy interior, and a fruit-forward finish. Sour Gush nails that progression in vape form: the first second of inhale is the sour shell, the mid is the sweet interior, and by the exhale the sour and sweet are running together. Unlike Sour Blue Dust, there is no powdery candy-dust layer here — Sour Gush leans wet-fruit rather than dry-candy.

Sour Gush is the flagship sour of the Geek Bar Pulse 15K — the fruit-burst lane of the Sour family, distinct from the candy-shell sours (Sour Straws, Sour Blue Dust, Drop Sour Savers). The naming references the "gush" of fruit flavor that hits when a soft-center sour candy bursts; the recipe targets the explosion of fruit body that those candies produce rather than a steady candy reference.

What that produces in the draw: a tangy sour shell on the inhale (sharper than the candy-style sours, but still under control), a sudden fruit-burst on the mid that fills the palate with a mixed-berry/citrus body, and a sweet finish that closes on the fruit rather than on a candy reference. The defining trait against Sour Straws and Drop Sour Savers is that the mid-draw is fruit-led, not candy-led. The sweetness comes from the fruit body itself rather than from a sugar-candy layer.

This is the highest-volume Sour family flavor on Geek Bar (the SV is in the top-4 of the entire Geek Bar catalog), which means it's the entry point most buyers use to enter the Sour lineup. From here, buyers who want more candy reference move to Sour Straws or Sour Blue Dust; buyers who want a sharper single-fruit pairing move to Sour Watermelon Drop or Sour Mango Pineapple.

The four-dimension profile places Sour Gush against the rest of the Sour family.

• Sour Lead — 8 of 10. The sharpest sour in the family. Sour Straws (5), Drop Sour Savers (6), Sour Blue Dust (6) all sit below. Sour Watermelon Drop comes closest at 7.
• Fruit-Burst Mid — 9 of 10. The defining trait. The fruit explosion on the mid is what makes the "gush" naming work. The candy-style sours don't carry this.
• Sweetness — 7 of 10. Lower than the candy sours (8-9) because the sweetness comes from fruit body rather than candy sugar.
• Candy Reference — 4 of 10. Lower than the rest of the family. The reference is the soft fruit-center inside a sour candy, not the candy shell.

Pick Sour Gush as the entry point to the Sour family — it's the broadest, highest-volume reading.

Sour Gush is one of the most-searched flavors in the Geek Bar catalog when buyers add the word "review" to the query — about 140 review-intent searches a month land here. That review volume is unusual: most flavors draw 20-50 review searches; Sour Gush more than doubles that. The reading from the data: shoppers want to confirm the sour level matches the name before they commit, and reviews are how they check.

The reviews block on the Pulse 15K product page filters Sour Gush specifically, with recency sort and verified-purchase tags on every entry. The most-repeated buyer notes line up with the taste profile above: the sour is real on the front, the fruit body is sweeter than expected, and the cross-comparison most often called out is against the candy-dust style of Sour Blue Dust.

Sour Gush is not currently in the Pulse X 25K, Mate 60K Kit or CLR 50K rotation. For Sour family flavors on the higher-puff Pulse X 25K chassis, Sour Mango Pineapple is the cross-device pick.

• Sour Blue Dust — blue raspberry candy with a sour-dust coating. Powdery rather than wet-fruit.
• Sour Mango Pineapple — tropical sour lane. Runs on Pulse 15K and Pulse X 25K.
• Sour Watermelon Drop — melon-candy sour, lighter sour than Gush.
• Sour Straws — straw-candy reference, medium sour, fruit-forward exhale.
