Icelandic Glacial Natural Spring Alkaline Water, 330 ml / 11

The Verdict

Let’s be blunt: most “alkaline water” is marketing dressed up as science. You can buy a $30 pitcher and make your tap water hit pH 9 in seconds. So why does Icelandic Glacial command a premium price for a 330ml bottle that’s gone in three gulps? Because it’s not actually about the pH — it’s about the source.

What’s Actually in the Bottle

This 330ml / 11.15 fl oz format is Icelandic Glacial’s smallest offering. The water comes from the Ölfus Spring in Iceland, a renewable source fed by rainfall that filters through layers of volcanic basalt rock. That natural filtration is what gives it a consistent pH of 8.4 — not added minerals, just geology.

You get a 24-pack of slim, BPA-free PET bottles. Each one has a clean, minimalist label that looks more like a skincare product than a beverage. The bottles themselves are surprisingly robust — reviewers consistently note they arrive without crushed corners, which is rare for multi-pack water on Amazon.

How It Actually Tastes

Here’s where Icelandic Glacial separates itself from the alkaline pack. Most high-pH waters (think Essentia or Core) have a distinct mineral bite — that slightly bitter, almost metallic finish that makes you wonder if you’re drinking liquid chalk. Icelandic Glacial doesn’t.

The taste is soft, almost sweet, with zero residual flavor. It’s the kind of water you’d serve to a guest who claims they can’t tell bottled water apart — they’d notice this one immediately. The 330ml size is ideal for a desk drawer, a lunchbox, or a tasting flight (yes, people do this).

What Buyers Consistently Praise

Across 220 ratings at 4.4 stars, the pattern is remarkably consistent. One reviewer wrote, “I’ve tried every premium water available — this one wins on taste, hands down. Crisp, clean, no weird alkaline aftertaste.” Another noted the practical side: “These small bottles are perfect for my kids’ lunches. They actually drink all of it.”

The basalt filtration story also resonates. Buyers who care about water quality appreciate that this isn’t reverse-osmosis water with minerals added back — it’s naturally occurring alkalinity, which is chemically different and arguably better for you.

Where It Falls Short

Let’s talk money. At roughly $1.50-$2.00 per 330ml bottle (the 24-pack pricing fluctuates), you’re paying a significant premium over domestic spring water. If your goal is simply hydration, this is overkill. If your goal is replacing your coffee-maker water for better-tasting brew, the cost adds up fast.

The plastic bottle is also a legitimate concern. Icelandic Glacial does offer glass bottles and larger PET formats, but this specific listing is single-use plastic. For a brand that markets itself on sustainability, the 330ml PET format feels like a compromise.

Who Should Buy This

Buy it if: You’re a water snob who can taste the difference between alkaline waters. You want the convenience of a small bottle that fits in a bag or cup holder. You’re hosting an event and want water that looks as premium as it tastes.

Skip it if: You’re looking for everyday hydration value. You’re concerned about single-use plastic. You just want high-pH water and don’t care about the source — a pitcher filter will do the job for a fraction of the cost.

FAQ

Q: Is 8.4 pH actually alkaline enough to matter? A: Yes — your body’s natural pH is around 7.4, so 8.4 is meaningfully more alkaline. But don’t believe the hype about it curing disease. It’s about taste and mineral content, not miracle health benefits.

Q: How does it compare to Essentia or Core? A: It’s smoother. Essentia has a more pronounced mineral taste; Core is similar but slightly heavier. Icelandic Glacial is the lightest, cleanest option of the three.

Q: Is this good for coffee brewing? A: Surprisingly yes. The balanced mineral content (low sodium, moderate calcium) extracts coffee well without scaling your machine. But at this price, you’ll want to use it for pour-over or espresso, not a full drip pot.

The Verdict

Icelandic Glacial isn’t the most affordable water, but it’s arguably the best-tasting alkaline water on the market. The source is legit, the packaging is solid, and the taste genuinely separates it from competitors. It’s a luxury purchase — treat it as such, and you won’t be disappointed.

Rating: 4.2/5 — Premium pricing drops it from a 5, but the product itself is nearly flawless. If you care about what you’re drinking, this is worth the splurge.
