Professor Crumb’s Feeding Ratio Quick Guide: Printable Sourdough Starter Chart

Take the guesswork out of feeding your sourdough starter!

Professor Crumb’s Feeding Ratio Quick Guide is an eight-page printable reference that explains common feeding ratios in clear, beginner-friendly language.

Inside the guide, you’ll find:

• The correct starter : flour : water ratio order

• A clear explanation of what ratios such as 1:1:1 and 1:2:2 mean

• A comparison of five common feeding ratios

• Sample feeding amounts written in grams

• Help choosing a ratio for your baking schedule

• Warm-room and cool-room guidance

• A simple calculator for building the amount of starter your recipe requires

• A worked calculation example

• Weekly refrigerator-maintenance guidance

• Starter-readiness clues

• A reusable feeding planner and notes page

The guide emphasizes observing your starter rather than depending on a perfect clock. Feeding speed can change with room temperature, flour, starter health and other kitchen conditions.
