Ranked: The Top 5 Sour Flavors of Geek Bar Pulse X 25K
Not all "sour" vapes are created equal. Some just tickle your tongue with a hint of tartness, while others make your mouth pucker instantly.
We tested the entire Geek Bar Pulse X 25K lineup to bring you the definitive ranking. Whether you want a "Warhead-style" challenge or a balanced fruit tart, here is your guide.
| Rank | Flavor | Sour Level | Vibe |
|---|---|---|---|
| #1 | Lemon Heads | 10/10 Extreme | Sharp Zest |
| #2 | Sour Straws | 8/10 High | Sugar Coated |
| #3 | Sour Apple Ice | 7/10 High | Crisp & Cool |
| #4 | Sour Fcuking Fab | 6/10 Medium | Complex Candy |
#1 The Extreme: Lemon Heads
Lemon Heads takes the crown. It is unapologetically aggressive.
- Sour Level: 10/10 (Face-Melting)
- Inhale: A sharp blast of citric acid that wakes up your senses immediately.
- Exhale: A pure yellow lemon zest flavor with just enough sugar to keep it vape-able.
- Verdict: Only for the brave. It mimics the actual hard candy perfectly.
#2 The Candy Sour: Sour Straws
Coming in a close second is Sour Straws.
- Sour Level: 8/10 (Tangy)
- The Experience: This flavor captures the texture of "Sour Sugar Sanding." It tastes like a mixed berry gummy belt rolled in sour dust. It starts with a strong kick but mellows out into a sweet berry finish.
#3 The Crisp Sour: Sour Apple Ice
Sour Apple Ice offers a "natural" kind of sourness.
- Sour Level: 7/10 (Tart)
- The Experience: Instead of candy sugar, this mimics the tart skin of a Granny Smith apple. The added Ice (Menthol) amplifies the crispness, making it incredibly refreshing rather than sticky-sweet.
#4 & #5 The "Balanced" Duo
Tying for fourth place are Sour Fcuking Fab and Sour Mango Pineapple.
- Sour Level: 5-6/10 (Balanced)
- The Experience: These aren't "sour" vapes in the traditional sense. The sourness is used purely to balance the heavy sweetness of the tropical fruit (Mango) or mixed berries (Fab). They are complex all-day vapes that won't give you "vaper's tongue."

Pro Tip: Use Pulse Mode
Did you know? Sour flavors hit harder in Pulse Mode.
The higher wattage (20W) vaporizes the acidic flavor notes more aggressively. If you want Lemon Heads to really sting (in a good way), flip that switch to Pulse Mode!
