Smeraldina Natural Water Brick

Eco-Friendly Tetrapak – Best Water in the World 

From the ancient granite rocks of Gallura: purity, lightness, award-winning excellence

Smeraldina Water: Sardinian Excellence Recognized Worldwide

Smeraldina Natural Mineral Water in Eco-Friendly Tetrapak is an extraordinarily pure water that originates from the depths of the ancient granite formations of the Monti di Deu in Gallura (northern Sardinia), a magical, uncontaminated territory where 300-400 million-year-old rocks naturally filter rainwater, giving it a delicate, balanced minerality, neutral pH, and that characteristic lightness that has repeatedly earned it the title of best mineral water on the planet at the Berkeley Springs International Water Tasting—the most prestigious and important global competition dedicated to mineral waters, where international experts blindly evaluate hundreds of waters from every continent, judging their purity, mineral balance, taste, and overall quality. Bottled (or rather, packaged) at the source in Tempio Pausania (SS) in innovative, eco-friendly Tetrapak packaging that drastically reduces the environmental impact compared to traditional plastic bottles, Smeraldina represents Sardinian regional excellence, innovation in sustainable packaging, and organoleptic quality recognized at the highest levels worldwide.

The chemical-physical characteristics reveal an oligomineral water (very low fixed residue 155 mg/L compared to the 500+ mg/L of medium-mineral waters or the 1500+ of those rich in salts) extremely light, microbiologically pure without the need for aggressive treatments thanks to the natural protection offered by the impermeable granite rocks which prevent contamination, slightly acidic pH 6,59 (neutral is 7,0) which makes it gentle on the stomach and body, temperature at the source 16°C constant all year round testifying to deep collection protected from surface temperature variations. The very balanced mineral content includes a moderate presence of bicarbonate (53,1 mg/L), chlorides (49,8 mg/L), very low sulphates (11,2 mg/L), silica (18,3 mg/L), low sodium (28,3 mg/L ideal for those who need to limit sodium intake), minimal potassium (1,4 mg/L), calcium and magnesium in traces (13,8 and 6,9 mg/L respectively).

This minimalist mineral composition gives Smeraldina the organoleptic characteristics that have won over international judges: a clean, neutral taste without any metallic mineral aftertaste or disturbing saltiness, a sensation of extreme lightness in the mouth where the water glides without leaving a heaviness, and a perceptible purity that makes it ideal for drinking neat while appreciating its quality, for making tea/coffee where it doesn't interfere with delicate aromas, for cooking where it doesn't alter the flavors of ingredients, and for infants and children who require very light water with a low mineral content.

Eco-friendly Tetrapak packaging represents a revolutionary sustainable innovation: the container is made of over 75% renewable plant-based materials (paper from responsibly managed FSC-certified forests + a cap made of plant-based plastic derived from sugarcane instead of petroleum), is completely recyclable in paper/cardboard waste collection, where it is separated and recycled to recover both the cellulose fiber and polymers, takes up significantly less space than glass or PET bottles (it stacks efficiently, reducing space for transportation and storage, thus reducing CO2 emissions), and perfectly protects the water from light and oxygen, preserving its purity.

The label may state “may have diuretic effects” referring to the very low salt content which promotes renal elimination of liquids (a characteristic of all oligomineral waters).

The roots of the Emerald Water sink into the primordial granites of Gallura

Gallura is a historical and geographical region in northeastern Sardinia characterized by unique landscapes dominated by monumental granite formations 300-400 million years old (dating back to the Paleozoic Era, when the current continents were still joined together in the supercontinent Pangea), shaped by erosion into fantastic shapes (the famous "tafoni" and giant boulders that dot the countryside and coastline). These granite rocks—composed primarily of quartz, feldspar, and mica—are impermeable, chemically inert (leaching minimal minerals), and function as a perfect natural filter: rainwater slowly seeps through natural fractures in the rock, percolating for years or decades through deep layers where it is mechanically filtered (solid particles remain trapped) and delicately mineralized, acquiring only trace amounts of dissolved minerals, emerging pristine in protected springs.

The Monti di Deu, where Smeraldina is born, are a remote, pristine territory in inland Gallura, a sparsely populated area with no intensive agriculture or polluting industries. Here, wild Mediterranean nature (holm oak, cork oak, juniper, myrtle, and mastic scrub, inhabited by mouflon, wild boar, and eagles) preserves the environmental purity that is reflected in the water's quality. Water is collected directly from the natural source with protected structures that convey the water without exposing it to contamination, and immediate bottling on site avoids transportation that could compromise quality.

International recognition at the Berkeley Springs International Water Tasting (an annual competition held since 1990 in West Virginia, USA, where waters from around the world are blindly evaluated by panels of experts according to rigorous criteria of appearance, smell, taste, mouthfeel, and aftertaste) testifies that Smeraldina is not just a local Sardinian excellence but a quality recognized at the highest levels worldwide, comparable or superior to the most famous international premium waters (Fiji, Voss, Evian, San Pellegrino).

Choosing Smeraldina means pure hydration, diuresis, and environmental sustainability

Oligomineral water like Smeraldina offers specific physiological benefits: optimal hydration without significant salt intake (0 calories, 0 significant sodium, 0 sugars, 0 everything except pure H2O), a diuretic effect favored by the very low fixed residue that stimulates kidney function by increasing urine production and facilitating the elimination of metabolic waste, digestive lightness thanks to a neutral pH and minimal mineral content that does not weigh down the stomach, compatibility with low-sodium diets essential for hypertensives or people with water retention who must limit sodium (28,3 mg/L is very low), suitability for newborns and the preparation of formula milk given that the mineral content is compatible with the delicate needs of the little ones (always check the specific label for pediatric indications).

The very low calcium and magnesium content also makes it very soft water, ideal for household appliances (coffee machines, irons) where hard water rich in limestone causes scale build-up.

Choosing sustainable Tetrapak packaging drastically reduces environmental impact: compared to traditional 1,5L PET bottles, Tetrapak reduces CO2 emissions from production/transport (it's much lighter), space (it stacks compactly, reducing transportation costs), and end-of-life (it can be recycled as paper, where it's already managed by established supply chains). The cap, made from plant-based plastic from sugarcane (bio-polyethylene), is chemically identical to petroleum-based plastic but derived from a renewable source with a better CO2 balance.

Choosing Smeraldina therefore means qualitative excellence (the best water in the world), physiological benefits (lightness, diuresis), and environmental responsibility (innovative sustainable packaging).
