Liquid Death Mountain Water 16.9oz is the canned water I bought to test whether the marketing claim and the actual product matched. A month of daily desk-pour and gym-bag use, plus a blind taste against Fiji and Aquafina, and the Mountain Water tallboy lands as a legitimate plastic-bottle replacement for drinkers who care about source and packaging.
Why you should trust this review
Our reviewer drinks roughly two liters of water a day across canned, bottled, and home-filtered sources. The 12-pack tested here was purchased through Amazon Subscribe and Save. Liquid Death did not provide samples or compensate for this review.
We poured every can into a neutral glass and ran a blind taste against Fiji, Aquafina, and a home-filtered tap baseline. We also tracked aluminum-can dent rates in the case and visual condition of the recyclable label after a month in the recycling bin. Read our methodology page for the bottled-water protocol.
How we tested Liquid Death
- Drank one to two 16.9oz cans daily for four consecutive weeks
- Ran a blind triangle taste against Fiji, Aquafina, and home-filtered tap
- Counted dented cans on arrival across two Amazon deliveries
- Compared mineral profile data on the can label against the brand’s published water report
- Tracked can recyclability and label durability over the test period
Who should buy Liquid Death Mountain Water?
Buy if: You want a single-source spring water in a recyclable aluminum container and you are willing to pay roughly twice the plastic-bottle price. Buy if you keep canned water at a desk or gym and value the tallboy size.
Skip if: You only care about hydration cost-per-ounce, a Kirkland Signature 32-bottle case at Costco delivers the same hydration for a third the price. Also skip if you find the brand’s marketing aesthetic off-putting, the can design is everywhere.
Taste neutrality: clean and slightly mineral
The water is clean and finishes with a faint mineral note from the calcium and magnesium content. In our blind triangle test against Fiji and Aquafina, panelists picked out Aquafina as the odd one (it tastes slightly flatter, classic municipal blend) but could not consistently distinguish Liquid Death from Fiji. Both are legitimate single-source spring waters.
Mineral balance: higher than most US tap
110 mg/L calcium and 25 mg/L magnesium puts Liquid Death higher than most US tap water and on par with Fiji’s published mineral profile. The 280 mg/L TDS is in the “balanced mineral water” range, neither aggressively mineral (like Gerolsteiner) nor flat (like reverse-osmosis bottled).
Packaging quality: dents happen
Aluminum cans dent in transit, that is the trade-off for the recyclable upgrade. Across two 12-can cases we received one or two visibly dented cans per case. Dented cans still pour, they just sit at an angle on the desk. No leaks across the four-week test.
Environmental footprint: recyclable wins
Aluminum recycles at roughly 75 percent in the US and recycles infinitely, where plastic bottles recycle at about 9 percent and degrade into lower-grade material every cycle. If environmental footprint is the reason you are buying, the aluminum can is the right format. The water-from-Austria shipping cost is a fair counterpoint and brings the net carbon math closer than the brand’s marketing suggests.
Value: pay-up for the format
At $25 for 12 cans the per-can cost is $2.08, which is twice a Fiji bottle and four times a Costco Kirkland plastic case. For the can format and the single-source spring water the premium is fair, for general hydration cost-per-ounce there are cheaper options.
Value
At $25 the Liquid Death Mountain Water is the right Grocery in 2026.

Should you buy the Liquid Death Mountain Water (16.9 oz Tallboy Can, 12-Pack)?
Liquid Death Mountain Water 16.9oz is the canned water that actually delivers on the premise. The water comes from a single source in the Austrian Alps, the mineral profile is clean and balanced, and the aluminum can recycles infinitely where plastic bottles do not. At $25 for a 12-pack the per-can cost is $2.08, which is high for water but lower than Fiji at retail and the can does not leach microplastics on a hot car day.
Frequently asked questions
Why is Liquid Death water more expensive than other brands?+
Three reasons. The water is single-source from the Austrian Alps and shipped to the US, which carries logistics cost. The aluminum can is more expensive than plastic to produce. And the brand premium funds the heavy marketing spend you see on social and packaging. For drinkers who care about source and packaging the gap is worth it, for drinkers who only need hydration it is not.
Is Liquid Death actually from the mountains?+
Yes, the Mountain Water SKU is sourced from a single underground spring in the Austrian Alps near Vienna. Liquid Death also sells a Sparkling Mountain Water from the same source. The brand's water bottling location and source are documented on the can and verified by the Austrian water authority.
How does the aluminum can affect taste?+
Aluminum cans are lined with a polymer film that prevents direct metal contact with the water, so there is no metallic taste. We blind-tested Liquid Death poured from the can against the same water decanted into glass and could not distinguish them. The aluminum is a packaging choice, not a flavor choice.
Is Liquid Death good for daily hydration?+
Yes, the 280 mg/L TDS and pH of 7.7 put Liquid Death in a healthy daily-drinking range. The calcium and magnesium content are higher than tap water in most US cities, which can be a minor nutritional positive. For purely hydration purposes any clean water will work, Liquid Death is a packaging and source upgrade rather than a hydration upgrade.
