Quick guide to Feeding Ratio for Sourdough Starters

As a general rule the lower the ratio of flour and water to starter (1:1:1) the less food the beneficial bacteria and yeasts have to eat meaning it will peak slower. 

Low Feeding Ratio 

A low ratio starter will peak faster as it has less food to eat and is less diluted. 

High Feeding Ratio

A high ratio starter (1:2:2 or above) will rise slower as it is more diluted and has more food to eat (ferment).
