I Tasted Liquid Death’s PB Cup Water: It’s a Delicious Trick, Not a Treat
Liquid Death and Feastables Made a Peanut Butter Cup Flavored Water—And It’s Weirdly Accurate
What Is This Drink Anyway?
Imagine cracking open a cold can of sparkling water, taking a sip, and tasting a peanut butter cup. Not "hint of peanut" or "whisper of chocolate"—actual peanut butter cup flavor. In liquid form. With bubbles.
That’s exactly what Liquid Death (the gothic-looking water brand in the tallboy cans) and Feastables (MrBeast’s snack company) teamed up to create. It’s called Liquid Death x Feastables: Peanut Butter Cup Sparkling Water, and it showed up just in time for Halloween 2026.
Important Point: This is a limited-edition seasonal release. Once it’s gone, it’s probably gone for good.
How Did We Get Here? A Quick Backstory
The "Hot Fudge Sundae" Water That Started It All
Back in late 2024, the reviewer (Griffin Parker) visited a fancy Van Leeuwen ice cream shop in New York City and found cans of Liquid Death Hot Fudge Sundae Sparkling Water—a collaboration between Liquid Death and Van Leeuwen.
- It tasted like hot fudge. In water.
- It was weird. But also kind of impressive.
- Griffin thought: "Surely this is the weirdest flavor they’ll ever make."
Spoiler Alert: It Wasn’t
Since then, Liquid Death has released:
- Fruity Pebbles Sparkling Water
- Strawberry Pop-Tart Iced Tea
- And now… Peanut Butter Cup Sparkling Water
The "innovation wheels never stop turning," as Griffin puts it.
The Big Question: What Does It Actually Taste Like?
The Short Answer
It tastes shockingly like a peanut butter cup. But it’s water. With bubbles. And your brain might short-circuit.
The Longer Answer (Broken Down)
| Flavor Note | How It Comes Across |
|---|---|
| Peanut Butter | Strong, authentic, roasted-peanut flavor. Leans more peanut than chocolate. |
| Chocolate | Present, but in the background—like the chocolate coating on a Reese’s. |
| Sweetness | Zero sugar, zero calories. The flavor comes from natural essences/extracts. |
| Mouthfeel | Carbonated water. Thin. Not creamy. This is the weird part. |
The "Oreo Coke" Comparison
Griffin compares it to OREO Coke (a real thing that existed briefly), which tasted more like Oreo crème filling than the chocolate wafers. Same energy here: peanut butter forward, chocolate supporting.
The Twist: It’s Actually Peanut-Free!
This might be the most surprising part.
Why This Matters
- Peanut allergies are serious. Many people can’t eat actual peanut butter cups.
- This water has ZERO peanuts. It uses flavor science to mimic the taste without the allergen.
- The press release led with "Allergen-free" as the very first bullet point.
Fun Behind-the-Scenes Detail
Griffin asked Liquid Death about allergens 10 months before release when the drink was first announced. They didn’t have an answer yet—but later thanked him with a hat (which he wears regularly). By launch time, "allergen-free" was the headline feature.
Important Point: If you or someone you know has a peanut allergy, this is a way to experience the flavor safely. Always double-check the label, but the brand confirms it’s peanut-free.
Wait—MrBeast? Feastables? Is This Just a Cash Grab?
The Controversy, Addressed Directly
Griffin knows people have strong opinions about MrBeast (Jimmy Donaldson) and Feastables. He gets "nasty comments" every time he covers this collab.
His Take (In ELI5 Terms)
"If I refused to cover products from every company with controversy, I’d have nothing left to write about."
He’s not saying the criticism is invalid. He’s saying his job is reviewing the drink, not auditing the corporation. There’s a famous phrase about "no ethical consumption under capitalism"—meaning every big company has messy stuff going on behind the scenes.
What This Means for You
- If you love MrBeast/Feastables: Cool, here’s a collab.
- If you don’t: You can skip it. No judgment.
- If you just want to know if the water tastes good: Keep reading.
Should You Actually Buy It? A Decision Guide
YES, Try It If…
- You like weird food experiments (pickle juice soda, garlic ice cream, etc.)
- You want to taste something your brain cannot logically process
- You can split a case with friends (so you’re not stuck with 11 cans you hate)
- You find a single can at Five Below (cheap way to test it)
- You have a peanut allergy and miss the flavor of peanut butter cups
NO, Skip It If…
- You want a refreshing, drinkable water for daily hydration
- You dislike artificial/natural flavor essences in sparkling water
- You’re buying a full case solo without trying it first ($$$ risk)
- You want something that tastes "good" in a traditional sense
The Verdict: "Worth Trying ≠ Good"
Griffin’s exact words: "Is it good? No, but it’s so interesting that it surpasses the need to be ‘good’."
What That Means
| Category | Rating |
|---|---|
| Accuracy to Peanut Butter Cup | (Scarily accurate) |
| Drinkability | (Confusing for your brain) |
| Novelty Factor | (Off the charts) |
| Reurchase Value | (Once is enough for most) |

FAQ
Does it actually have peanut butter in it?
No. It’s peanut-free. The flavor comes from natural flavor extracts/essences designed to mimic peanut butter and chocolate without using the actual allergens.
Is it sweet? Does it have sugar?
No sugar, no calories. It’s sparkling water with added flavor. The sweetness you perceive is your brain associating the flavor notes with the candy—not actual sweetener.
Where can I buy it?
Limited release. Check Five Below for single cans, or look for cases online/retail where Liquid Death is sold. It’s seasonal (Halloween 2026), so availability is limited.
Why does Liquid Death keep making weird flavors like this?
Their whole brand is built on "murder your thirst" marketing + absurd limited editions that get people talking. It works—people buy them for the story, the photo, the "I tried this" factor.
Is this better or worse than the Hot Fudge Sundae water?
Different vibe. Hot Fudge Sundae was "chocolate sauce in water." This is "peanut butter cup in water." Both are technically impressive flavor mimicry. Both are weird to drink. Neither is "refreshing" in the normal sense.
