Before sparkling water was a lifestyle choice, before it came in pastel cans with minimalist branding, and long before anyone discussed “seltzer culture,” people were traveling to Hot Springs, Arkansas specifically to drink from the spring that would become Mountain Valley.
The brand was founded in 1871. By 1928, it was the first bottled water shipped coast to coast in the United States. It has been served at the White House and in the homes of foreign dignitaries. Top Chefs boil their handmade pasta in it. Bartenders build their best spritzes around it. And it has won 19 awards from the Berkeley Springs International Water Tasting, including four “Best in the World” honors—more than any other American spring water.
That is a long history to back up what is now sold alongside Bubly and LaCroix at the grocery store.
Quick answer: Mountain Valley Sparkling Spring Water is one of the genuinely best American spring waters available. The source is protected, the mineral profile is real (74mg/L calcium, 7.3mg/L magnesium, naturally alkaline pH 7.3 to 7.7), and the packaging is glass. The sparkling version carries the same natural character with added carbonation. It is worth it if you are willing to pay a small premium over standard seltzer.

The Source: What Makes Mountain Valley Different
Mountain Valley Spring Water comes from a single protected spring in the Ouachita Mountains (pronounced “WASH-ah-taw”) near Hot Springs, Arkansas. The water filters through layers of limestone, marble, and quartz over what the geological record shows as thousands of years before reaching the surface. That filtration process gives it calcium, magnesium, potassium, and a naturally alkaline pH between 7.3 and 7.7, documented on the label.
Confirmed mineral composition:
- Calcium: 74.0 mg/L
- Magnesium: 7.3 mg/L
- Potassium: 1.0 mg/L
- Total Dissolved Solids (TDS): 220 mg/L
- pH: 7.8
- Sodium: Near Zero
That 220 mg/L TDS places it solidly in mineral water territory, more than Saratoga (under 150 mg/L) but less than San Pellegrino (around 1,109 mg/L). The sodium content is essentially zero, which is a meaningful point for people watching their sodium intake.
Nothing is added. Nothing is removed. The water that comes from the spring goes into the bottle through a sealed system with no human contact. From a source integrity standpoint, it is about as straightforward as American spring water gets.
The spring is located in Garland County, Arkansas, adjacent to Hot Springs National Park. Mountain Valley has managed and monitored its source since 1871, and the geological record of the spring remains unmarred.
What Mountain Valley Sparkling Tastes Like
The taste profile is clean, crisp, and subtly mineral. Somewhere In Arkansas, a regional lifestyle publication, described it as “very clean and crisp and super refreshing. Although the taste is very neutral there is a sense of the minerality which in my opinion is what gives the water its special crispness.”
That is an accurate description. Mountain Valley Sparkling is not trying to compete with the aggressive bubble intensity of Topo Chico or the heavy mineral character of Gerolsteiner. It is a naturally alkaline spring water with medium-bold carbonation, a clean finish, and none of the slightly sour edge that comes with more acidic sparkling waters.
The naturally alkaline pH is a practical benefit for daily drinkers. Most sparkling waters are mildly acidic (pH around 5) because dissolved CO2 forms carbonic acid. Mountain Valley’s naturally alkaline source slightly buffers this, making it a gentler option for people concerned about daily acidity.
The Mountain Valley Sparkling Water Lineup
Mountain Valley Sparkling Spring Water (Plain) The flagship sparkling product. The same spring water as the still version, with carbonation added during the glass-bottling process. Zero calories, zero sugar, zero sweeteners. Available in green glass bottles (750 mL, 1L, and 333 mL sizes) and a 16oz recyclable aluminum bottle.
The Sparkling Essence Line (Flavored) Mountain Valley offers flavored sparkling spring waters under its Sparkling Essence line. These add natural fruit essences to the alkaline spring water base with no added sugar, calories, or artificial sweeteners.
- White Peach: The standout flavored option. It features a fragrant, sweet peach aroma that is reminiscent of a fresh stone fruit, but the taste is completely dry and crisp. The carbonation keeps the fruit note light.
- Key Lime: A zesty, citrusy choice. It uses natural key lime essence to provide a clean citrus brightness that contrasts nicely with the mineral finish of the spring water.
- Blackberry Pomegranate: A deeper berry combination. The blackberry provides a dark, jammy aroma, while the pomegranate adds a slightly tart edge on the finish. It is complex and refreshing.
How Mountain Valley Compares to Other Premium Waters
| Feature | Mountain Valley | San Pellegrino | Saratoga | Topo Chico |
|---|---|---|---|---|
| Source | Ouachita Mountains, AR | Italian Alps | New York springs | Monterrey, Mexico |
| TDS | 220 mg/L | 1,109 mg/L | Under 150 mg/L | ~400 mg/L |
| pH | 7.3 to 7.7 (Alkaline) | 5.6 (Acidic) | Neutral (~7.0) | Mildly Acidic |
| Sodium | Near Zero | 36 mg/L | Low | Low |
| Bottle | Green Glass / Can | Green Glass | Cobalt Blue Glass | Glass / Can |
| Origin since | 1871 | 1899 | 1872 | 1895 |
The alkaline pH is a meaningful differentiator for Mountain Valley. Most sparkling waters, including San Pellegrino and Topo Chico, are mildly acidic. Mountain Valley’s naturally alkaline source means it is the gentler daily sparkling water option for people who drink a lot of it.
The near-zero sodium content also matters for people on low-sodium diets. San Pellegrino’s 36 mg/L sodium is not alarming for most people, but at several liters per day it adds up. Mountain Valley eliminates that concern.
Is Mountain Valley Sparkling Water Worth Buying?
It depends on what you are looking for.
If you want the most economical sparkling water, Mountain Valley is not it. It runs $2 to $4 per glass bottle at retail, more per ounce than LaCroix, Bubly, or Kirkland.
If you want the best everyday American spring water in glass, with a naturally alkaline pH, documented mineral content, zero sodium, and the most awards of any domestic spring water, Mountain Valley is the answer.
The sparkling version specifically is excellent for cocktails and mocktails, a point the brand leans into with chef and bartender recipes on their site. The medium-bold carbonation and alkaline base make it a balanced mixer without the mineral heaviness that can clash with certain spirits.
