What is Fermentation Schedule?
Fermentation Schedule
A fermentation schedule is the timed plan that tells you when to mix, bulk ferment, shape, and cold ferment your dough — and for how long at each stage. It's the difference between a 16-hour sourdough that costs you $2.40 in ingredients and a 4-hour sourdough that costs you $1.80 because you skip the overnight cold proof. Your schedule directly controls flavor development, labor hours, oven capacity, and ingredient costs.
Example
You bake 40 sourdough loaves per week. Your recipe: 500g bread flour, 350g water, 100g active starter, 10g salt. Ingredient cost per loaf: $1.05. Selling price: $6.50. Margin: $5.45 per loaf (83.8%). Your current schedule: 4-hour bulk ferment at 72°F, shape, 2-hour bench rest, bake. Problem: you're shaping at 1 PM, baking at 3 PM, and your croissant oven is booked 1–3 PM. You lose 20 loaves per week because you can't bake them. That's $109 lost margin per week ($5.45 × 20 loaves). Annual loss: $5,668. You change your fermentation schedule: 5-hour bulk ferment at 70°F (starting at 6 AM), shape at 11 AM, 1-hour bench rest, 24-hour cold ferment in the fridge (overnight and all next day), bake at 7 AM the following morning. Same ingredient cost ($1.05). Same selling price ($6.50). But now you shape once per day, use the fridge (which sits empty at night), and bake at 7 AM when the oven is free. You fit all 40 loaves into your production calendar. No new equipment. No new ingredient cost. You gain $5.45 × 20 loaves = $109 per week, or $5,668 per year. You test a second schedule: 12-hour overnight bulk ferment at 65°F (starting at 6 PM, finishing at 6 AM), shape at 6:30 AM, 2-hour bench rest at room temperature, 48-hour cold ferment (fridge), bake at 6:30 AM on day 3. Ingredient cost: still $1.05. Selling price: $7.00 (you market it as 'three-day fermented'). Margin: $5.95 per loaf (85%). You bake 40 loaves per week across three batches (Monday, Tuesday, Wednesday shapes; Thursday, Friday, Saturday bakes). Your oven is booked with croissants 1–3 PM every day. Your sourdough bakes at 6:30 AM when the oven is empty. You sell out every week. New margin per week: $5.95 × 40 = $238. Old margin per week: $5.45 × 20 (only half your loaves baked) = $109. Gain: $129 per week, or $6,708 per year. The fermentation schedule change — not a new recipe, not a price increase, just timing — adds $6,708 annual profit.
Understanding Fermentation Schedule
Your fermentation schedule is not a suggestion — it's a production calendar that locks in your costs and quality. Take a basic sourdough loaf: 500g bread flour ($0.85), 350g water (free), 100g active starter (cost-shared across 40 loaves, $0.12), 10g salt ($0.08). Total ingredient cost: $1.05. But the schedule you choose changes everything. A bulk fermentation of 4 hours at 72°F followed by a 12-hour cold ferment in the fridge takes up a mixer for 30 minutes, an oven slot for 25 minutes, and uses your fridge space overnight. That same loaf on a 16-hour bulk ferment at 68°F uses the mixer for 30 minutes but ties up your bench for 16 hours and forces you to shape at 11 PM if you want to bake at 7 AM. Your schedule determines whether you can fit 3 batches or 1 batch per day in the same oven. Cold fermentation schedules save you money because they extend proof time without tying up your hands or bench space. A 48-hour cold ferment in the fridge costs you nothing but fridge space and time. Your dough develops more flavor — more acetic acid, more complex notes — which justifies a higher price. A $6.50 loaf with a 48-hour cold ferment margin is $5.45 (16.9% food cost). That same loaf rushed through a 6-hour bulk ferment and sold for $5.50 has a margin of $4.45 (19.1% food cost). The cold ferment schedule earns you $1.00 more per loaf. Across 50 loaves a week, that's $50 more gross profit with zero extra ingredient cost — just patience and a fridge. Bulk fermentation timing affects your oven schedule and labor. If you bulk ferment for 3 hours, you shape at 11 AM and bake at 1 PM. If you bulk ferment for 5 hours, you shape at 1 PM and bake at 3 PM. If your oven is booked with croissants from 1 PM to 3 PM, the 5-hour schedule breaks your day. You either buy a second oven, delay the croissant batch, or reduce sourdough volume. Your fermentation schedule either fits your existing equipment or forces you to buy more. A 12-hour overnight bulk ferment with a 2-hour cold proof lets you shape at 6 AM, proof in the fridge all day, and bake at 5 PM when the oven is free. Same dough, same flavor, zero equipment cost. Temperature changes everything in your fermentation schedule. A bulk ferment at 75°F takes 3 hours. At 70°F, it takes 4.5 hours. At 65°F, it takes 6 hours. A cold ferment at 38°F takes 48 hours. At 42°F, it takes 36 hours. Your schedule is not portable — it's locked to your bakery's ambient temperature. If you move locations or your HVAC breaks, your schedule breaks. A sourdough that proofs perfectly in winter (68°F ambient) may over-ferment in summer (78°F ambient) on the same 16-hour schedule. You either adjust timing (shorter bulk, longer cold proof) or lose loaves to over-fermentation. Your fermentation schedule is a living document tied to your specific space.
How BakeOnyx Helps
BakeOnyx lets you log your fermentation schedule for every recipe and track how it affects your daily oven and bench capacity. When you enter a sourdough recipe with a 12-hour bulk ferment and 48-hour cold proof, BakeOnyx shows you exactly when you shape, when you bake, and which oven slot it uses. Change your schedule to a 5-hour bulk ferment and BakeOnyx recalculates your production timeline and flags conflicts with other recipes. Your staff sees the updated schedule on their phone before they arrive, so they know whether to prep dough at 6 AM or 2 PM. You stop guessing whether a new fermentation schedule will fit your bakery.
