Reminders to feed your sourdough starter: the one baking task you can't skip

A sourdough starter is a living culture — a community of wild yeast and bacteria that needs regular feeding to stay active and produce the rise that makes sourdough bread worth baking. Neglect it for a couple of days and it goes dormant or spoils. Miss a feeding window before a big bake and you end up with flat bread. The challenge is that feeding schedules — typically every 12 hours during active use, or every 24 hours for maintenance — don't correspond to any obvious daily trigger. They're easy to forget when you're not in active baking mode. A phone call reminder solves this cleanly.

How sourdough feeding schedules work

An active starter being prepared for baking typically needs feeding every 12 hours for 2–3 days before use. A maintenance starter kept at room temperature needs feeding every 24 hours. A starter in the fridge can go 1–2 weeks between feedings, but needs to be brought to room temperature and fed at least 12 hours before baking.

The most common failure point is the pre-bake schedule: you plan to bake on Sunday, so you need a fed starter by Saturday morning, which means feeding Friday evening and Saturday morning. That chain of timing is easy to lose track of when you're managing a weekend.

Setting up sourdough reminder calls

For active baking preparation, create a temporary recurring reminder every 12 hours — for example, 8 AM and 8 PM for two days before your planned bake. The message can include the feeding ratio if you tend to forget: 'Feed starter: 1:1:1 ratio — 50g starter, 50g flour, 50g water.' Set an end date so the 12-hour reminders stop after the preparation window.

For a maintenance starter, a single daily reminder at a consistent time is enough: 'Feed sourdough starter today.' ReminderIt's every-N-days scheduling works well here — if you maintain a weekly baking schedule, every 6 or 7 days with a reminder the evening before preparation begins.

Using skip dates for fridge resting periods

When your starter goes into the fridge for a rest, you don't need the daily feeding reminder. Rather than deleting the reminder, use ReminderIt's skip dates feature to pause it for the number of days the starter will be stored. When you take it out to prepare for the next bake, remove the skip and the schedule resumes normally.

Sourdough baking is one of those hobbies where a small system pays disproportionate dividends. The bread is better when the starter is properly maintained, and properly maintained means a schedule you actually follow.
