Your Low Carb Sourdough Starter and the Magic of Water

The Best Water for Your Low-Carb Sourdough Starter

spring water

Why Water Matters

Your sourdough starter is alive with wild yeast and bacteria that need the right environment to thrive. Water isn’t just for mixing—it provides essential minerals that feed these microorganisms and help them ferment properly.

Spring Water is Your Best Choice

Why spring water works so well:

Contains natural minerals (calcium, magnesium, potassium) that yeast needs
Has a neutral pH around 7.0
No chlorine or chemicals that kill beneficial bacteria
Naturally filtered and clean

What Makes Water Good or Bad for Starters

✅ Good Water Choices:

Spring water (pH around 7.0)
Filtered tap water (if chlorine is removed)
Well water (if tested and clean)

❌ Bad Water Choices:

Distilled water – No minerals = weak starter
Reverse osmosis water – Too pure, missing nutrients
Tap water with chlorine – Kills beneficial microbes
Alkaline water – pH too high, slows fermentation

Recommended Spring Water Brands

Canada:

Compliments (~pH 7.0)
Eska (pH 6.8)

USA:

Crystal Geyser (pH 6.9-7.0)
Poland Spring (~pH 7.0)
Arrowhead (pH 6.8-7.0)

What About Water Filters?

Most pitcher filters remove too many minerals or change the pH. If you want to use filtered water:

Test your water before and after filtering
Look for filters that retain minerals
Check that pH stays around 7.0

Using Well Water

Well water can work if it’s:

Clean and food-safe
Not treated with chlorine or salt softeners
Has moderate mineral content
Neutral pH (around 7.0)

Tip: Test your well water first, as quality varies widely.

How to Fix a Struggling Starter

If your starter is weak or inactive, bad water might be the problem:

Switch to spring water immediately
Keep only 2 tablespoons of your healthiest starter
Feed with spring water + low-carb flour every 12-24 hours
Continue until you see bubbles and activity return

The Bottom Line

For a healthy, active low-carb sourdough starter, use spring water with a neutral pH and natural minerals. It’s the simplest way to give your starter the best environment to thrive and make delicious bread.

Remember: Your starter is a living culture. Give it the right water, and it will reward you with better fermentation and tastier bread.
