My sourdough starter was flat for weeks until I switched from tap to filtered water
I kept feeding my starter with water straight from the kitchen faucet, and it just sat there like a sad pancake. After reading a forum post from someone in Portland, I tried using filtered water from my fridge instead. The next morning it had doubled in size and was full of bubbles. I guess the chlorine in our city water was killing the good stuff. Anyone else have to change their water source to get things going?
Our city water in Toledo is heavily treated too. I had the exact same problem with my starter last winter. Switching to bottled spring water fixed it almost overnight.
Wait, you can really taste the chlorine that much? I always thought that was just people being picky... but hearing @nancy_adams say bottled water fixed her starter makes me wonder.
