In the Zymo app

A schedule that moves when your dough does.

Zymo builds the same timeline on your phone, then runs it: a countdown for each stage, reminders for every fold, and when the dough needs another half hour, the rest of the day shifts with it. Bake plans are part of Zymo Pro.

  • Pick a recipe and when you want bread
  • Reminders for feeds, folds, shaping and baking
  • Tap +30 min and every later step moves

How the planner works

A sourdough bake is a chain of steps, each waiting on the one before it. If you know roughly how long each step takes, you can start from the end, the moment you want bread, and count backward. That is all this planner does, but it saves a lot of scribbled arithmetic and catches steps that would land at 3 a.m.

The default timings come from Zymo's Everyday country loaf: 45 minutes to mix and rest, about 4 hours of bulk fermentation with three sets of stretch and folds, 30 minutes to shape, an overnight cold proof and 45 minutes in the oven. Change any of them to suit your recipe and kitchen.

Around a 9 to 5 job

Sourdough schedule for a 9 to 5
WhenStep
Monday 7:30 AMFeed your starter at a high ratio, such as 1:5:5, before work
Monday 5:30 PMMix after work
Monday 6:15 PMBulk fermentation, folds through the evening
Monday 10:15 PMShape, then into the fridge
Tuesday 6:45 PMScore and bake after work
Tuesday 7:30 PMOut of the oven

The fridge does the waiting while you are at work. A high feeding ratio slows the starter so it peaks in the evening; the starter feeding calculator gives the grams.

Making the schedule fit your day

  • The cold proof is your buffer. It can usually stretch or shrink by several hours, so use it to move the bake to a convenient time.
  • The feeding ratio moves the start. A higher ratio lets you feed earlier and still have a starter at its peak when you mix.
  • Temperature moves bulk. Warm kitchens shorten it and cool ones lengthen it. Check the bulk fermentation chart for your dough temperature before setting the bulk time.
  • Let it cool. The crumb is still setting when the loaf comes out of the oven. Slicing it hot is a common cause of a gummy loaf, so plan at least an hour before you eat it.

When the dough does not follow the plan

It often will not, and that is fine. Times are estimates; the dough is the real signal. If bulk is slow, give it more time and shorten the cold proof to keep your bake time. If it is racing ahead, shape early and let the fridge slow everything down.

Questions

Frequently asked

  • Usually about 24 hours from feeding your starter to slicing the loaf, but most of that is waiting. Hands-on time is closer to 30 to 60 minutes. An overnight cold proof is what stretches the timeline, and it is also what makes it easy to fit around a day.
