Best Alkaline Waters In Glass Bottles Review
Mountain Valley Spring Water Glass
ADVANTAGES
LIMITATIONS
There’s something undeniably refined about cracking open a glass bottle of Mountain Valley Spring Water—its clean, crisp profile and smooth mineral balance make it a top-tier choice for those who prioritize purity and taste. Sourced from a protected Ozark Mountain spring and bottled in premium glass, this water delivers a noticeably clean finish with subtle natural minerals that enhance, not overpower, its flavor. For health-conscious drinkers and culinary enthusiasts alike, it solves the common frustration of flat, chemically-tasting bottled water that lacks character or authenticity.
In real-world use, the 1-liter glass bottles hold up well in refrigeration and pouring, offering a satisfying weight and elegance that plastic simply can’t match. The water’s neutral pH and low total dissolved solids (TDS) make it ideal for daily hydration, coffee brewing, and even pairing with fine meals—where water quality can elevate or ruin delicate flavors. While it’s not marketed as highly alkaline, its natural balance appeals to purists who prefer a more subtle mineral profile over aggressive alkalinity. The glass packaging ensures zero leaching and superior freshness, though the bottles are heavier and more fragile than alternatives.
Compared to other alkaline waters in glass, Mountain Valley stands out for its old-world reliability and taste-first philosophy, positioning itself as a quieter luxury rather than a high-pH performance product. It’s best suited for home use, wellness routines, or gifting—where presentation and purity matter more than portability. While Hallstein offers higher alkalinity and a more premium story, Mountain Valley delivers a more accessible, everyday-elegant experience with consistent quality and trusted sourcing.
Icelandic Glacial 11.16 Fl Oz Bottles
ADVANTAGES
LIMITATIONS
When portability meets purity, Icelandic Glacial’s 11.16 fl oz mini bottles shine as a go-to for on-the-go hydration with a wellness edge. Each bottle delivers naturally alkaline water straight from the Ölfus Spring in Iceland, boasting a stable pH of 8.4—thanks to volcanic filtration—that helps neutralize acidity without artificial enhancements. The compact size fits perfectly in gym bags, purses, or airplane seat pockets, solving the all-too-common issue of bulky bottles that are impractical for travel or daily commutes.
These small but mighty bottles are made from high-grade rPET plastic, making them lightweight, shatterproof, and fully recyclable—ideal for eco-conscious users who don’t want to sacrifice convenience. In testing, the water maintains a crisp, clean taste with a soft minerality that’s refreshing post-workout or during long flights. While the plastic packaging isn’t glass, it’s among the most sustainable plastic options available, especially given Iceland’s geothermal-powered bottling process. However, the smaller volume means you’ll go through them quickly if relying on them for full-day hydration.
Against larger formats like the 16.9 fl oz pack or Hallstein’s glass bottles, this size trades volume for ultra-portability and ease of use, making it ideal for travelers, office workers, or parents packing lunchboxes. It’s not the most eco-luxurious option, but it strikes a rare balance between sustainability, alkalinity, and convenience. While Hallstein offers a more premium sensory experience, Icelandic Glacial’s mini bottles deliver consistent, on-demand alkaline hydration in a format that’s simply easier to carry.
Icelandic Glacial Alkaline Spring Water
ADVANTAGES
LIMITATIONS
For those who want bulk hydration without compromising on alkalinity or sustainability, the 16.9 fl oz pack of Icelandic Glacial is a smart, high-value solution. Each 500 mL bottle maintains the same natural pH of 8.4, sourced from the pristine Ölfus Spring—one of the world’s purest aquifers—giving you consistent alkaline benefits across every sip. The larger size means fewer refills throughout the day, making it ideal for households, offices, or fitness routines where hydration demands are constant.
The rPET plastic bottles are BPA-free and fully recyclable, aligning with eco-conscious values, while the larger pack reduces packaging waste per ounce compared to smaller formats. In daily use, the water tastes clean and slightly crisp, with minimal mineral interference—great for chugging after a run or pairing with meals. It doesn’t have the luxurious mouthfeel of glass-bottled artesian waters, but it delivers reliable performance and consistent alkalinity at scale. The plastic does warm faster than glass, so keeping it chilled requires planning.
Positioned between the mini bottles and premium glass options, this pack is the sweet spot for value-driven buyers who still care about source quality and environmental impact. It outperforms single-serve plastics in sustainability and beats many alkaline brands in natural sourcing credibility. While it lacks the elevated sensory experience of Hallstein or Mountain Valley in glass, it offers far better cost-per-bottle efficiency and practicality—making it the go-to for families or frequent users who want alkaline water as a daily habit, not a luxury.
Hallstein Artesian Alkaline Still Water
ADVANTAGES
LIMITATIONS
Hallstein Artesian Water doesn’t just raise the bar for alkaline water—it redefines what premium hydration should feel like. Sourced from a deep artesian aquifer in the Austrian Alps, this water emerges with a natural pH of 8.3 and zero sodium, filtered over eight years through pure limestone—delivering a velvety, crisp mouthfeel that’s unmatched in the category. For discerning drinkers who treat water as a foundational element of wellness and taste, Hallstein solves the gap between mass-market alkaline brands and truly exceptional, unfiltered natural water.
In real-world testing, the 25.4 fl oz glass bottles exude luxury—from the weight in hand to the clean, oxygen-rich taste that lingers without bitterness. The absence of TOC (Total Organic Carbon) ensures absolute purity, making it ideal for pairing with wine, tea, or gourmet cuisine where water can amplify flavors. Each sip feels refreshingly alive, thanks to high dissolved oxygen levels developed during its natural filtration journey. However, the high price and limited quantity per pack make it less practical for everyday family use or high-volume consumption.
When compared to Icelandic Glacial or Mountain Valley, Hallstein stands as the undisputed premium choice—not just for alkalinity, but for holistic water quality. It’s the only one in this lineup that’s unfiltered, untreated, and entirely self-replenishing, drawing from a closed-loop aquifer untouched by surface pollution. While it’s significantly more expensive than other options, it justifies its status as the best overall with unmatched sourcing integrity, taste, and environmental stewardship. For those who want the pinnacle of natural alkaline water, Hallstein is worth every sip.
Choosing the Right Alkaline Water in Glass Bottles
Alkalinity (pH Level)
The core reason people choose alkaline water is for its potential health benefits, and this is directly tied to its pH level. Most alkaline waters fall between a pH of 8 and 9. A higher pH means the water has a greater ability to neutralize acid in your body. While a pH of 8.4 (like Icelandic Glacial) is a good starting point, consider what level feels best for you. Some individuals may find overly alkaline water has a slightly bitter taste or causes mild digestive upset. Start with a mid-range pH and adjust based on your preference and how your body responds. If you’re new to alkaline water, gradually increasing your intake is advisable.
Source & Purity
Where the water comes from significantly impacts its mineral content and overall purity. Water sourced from protected aquifers (like Hallstein) or natural springs (like Icelandic Glacial and Mountain Valley) generally offers a cleaner, more naturally occurring mineral profile. Look for descriptions that highlight natural filtration processes – for example, filtration through limestone. Avoid brands that rely heavily on artificial alkalization or added minerals, as these may not provide the same benefits as naturally occurring alkalinity. Water that is “unfiltered, untreated, and uncompromising” (Hallstein) suggests a commitment to preserving the water’s natural qualities.
Bottle Material & Sustainability
Since you’re specifically looking for glass bottles, this is already a great step towards sustainability! Glass is endlessly recyclable and doesn’t leach chemicals into the water like some plastics can. However, consider the bottle’s design and weight. Heavier glass bottles are more durable but less convenient for carrying. Also, examine the brand’s broader commitment to sustainability. Some brands (like Icelandic Glacial) use recycled PET (rPET) in their bottle production and emphasize recyclable packaging. Consider the entire lifecycle of the product, not just the bottle itself.
Taste & Mineral Content
Alkaline water doesn’t just offer potential health benefits; it should also taste good! The mineral content contributes significantly to the water’s taste. Some alkaline waters have a crisp, clean taste (Hallstein), while others may have a more noticeable mineral flavor. Dissolved oxygen levels can also impact taste, creating a “body” to the water. Consider your personal preference – do you prefer a very neutral-tasting water, or one with a more distinct flavor profile?
Size & Packaging Options
Think about how you plan to use the water. Do you need individual bottles for on-the-go hydration (Icelandic Glacial 11.16 Fl Oz Bottles)? Or are you looking for larger packs for home use (Icelandic Glacial 500 mL Pack of 24, Mountain Valley 1 Liter Pack of 12)? Consider the convenience of the packaging and whether it fits your lifestyle.
