Natural mineral water contains dissolved minerals but no macronutrients or problematic ingredients. DIY mineralization allows you to control the exact mineral profile and avoid potential contaminants while using the cleanest filtered water base.

Why This Recipe is Seed Oil Free
Commercial Eau minéral naturelle from Ain atlas often contains inflammatory seed oils like canola, soybean, or sunflower oil. This homemade version replaces them with healthier fats like butter, ghee, coconut oil, or avocado oil — giving you the same great taste without the processed oils.
Ingredients
Filtered water
20 liters (5.28 gallons) · Berkey or similar gravity filter system
Pure base water free from chlorine, fluoride, and contaminants that will carry the mineral blend
Food-grade sea salt
4g (about 3/4 teaspoon) · Redmond Real Salt
Provides sodium and trace minerals naturally found in mineral springs
Magnesium chloride
2g (about 1/2 teaspoon) · Ancient Minerals Magnesium Chloride Flakes
Essential mineral that contributes to the characteristic taste and health benefits of natural spring water
Provides calcium content typical in mountain spring waters and improves water taste
Potassium chloride
0.5g (about 1/8 teaspoon) · NOW Foods Potassium Chloride Powder
Adds potassium content found in natural mineral sources and balances electrolyte profile
Instructions
Step 1. Start with 20 liters of the highest quality filtered water you can produce. If using a Berkey system, filter your municipal water through both black and fluoride filters. The water should taste completely neutral with no chlorine or chemical aftertaste - this clean base is critical because any off-flavors will be amplified when minerals are added.
Step 2. Create your mineral concentrate first. In a small glass bowl, carefully measure 4g Redmond Real Salt (about 3/4 teaspoon), 2g magnesium chloride flakes (1/2 teaspoon), 1g calcium chloride (1/4 teaspoon), and 0.5g potassium chloride (1/8 teaspoon). Use a precise digital scale for accuracy - mineral ratios matter for both taste and safety. Whisk the dry minerals together until evenly distributed.
Step 3. Dissolve the mineral blend in stages to prevent clumping. Take 500ml (2 cups) of your filtered water and heat to just under boiling (about 185°F). Remove from heat and slowly whisk in the mineral blend, stirring continuously for 3-4 minutes. The minerals should dissolve completely with no visible particles. This creates your concentrated mineral solution.
Step 4. Cool the mineral concentrate to room temperature, then slowly pour it into your remaining 19.5 liters of filtered water while stirring gently. Use a long-handled spoon and stir in a figure-8 pattern for 2-3 minutes to ensure complete distribution. The water should remain clear with no cloudiness or sediment.
Step 5. Let the mineralized water rest for 30 minutes to allow the minerals to fully integrate. Taste test: the water should have a clean, slightly mineral taste - crisp and refreshing without any saltiness or bitterness. If it tastes too mineral-heavy, dilute with additional filtered water. If too flat, you can add a tiny pinch more sea salt.
Step 6. Store in glass containers only - never plastic, as it can leach chemicals into your pure water. Fill glass bottles or jars, leaving 1 inch headspace. Label with the date and 'DIY Mineral Water.' Store in a cool, dark place away from direct sunlight. The mineralized water will stay fresh for 2-3 weeks when properly stored. Shake gently before each use as minerals may settle slightly over time.
Storage
Store in glass containers in cool, dark conditions. Shelf life: 2-3 weeks. Minerals may settle slightly - shake gently before use. Never store in plastic containers.

Massive upfront investment in filtration system pays off long-term. After initial setup, each batch costs virtually nothing to make. Commercial mineral water markup is enormous - you're paying mostly for plastic bottles and marketing.
