Documenting Your Sourdough Progress — Beginner's Guide

Simple, practical system to track feedings, recipes and bakes so your sourdough skills improve fast.

What to Expect

A simple, consistent log will accelerate your learning: you will stop repeating the same mistakes, learn how your starter and dough react to temperature and flour, and reproduce good loaves reliably.

What you'll learn:

  • ✓ How to recognize an active starter by objective measures
  • ✓ How proofing time shifts with temperature and dough strength
  • ✓ Which variables are worth changing and which are noise

💭 Tracking takes a little time at first, but after a few bakes it becomes a 5-minute habit that pays off in predictable results.

What You Need

Must have:

Active sourdough starter

Visible rise in a glass jar for starter within expected time after feeding

⚠️ Create a starter first → more

Digital kitchen scale

Measures grams accurately

⚠️ Buy one — weight is the single most important reproducible variable

Notebook or digital document

Dedicated place to keep entries

⚠️ Use a simple spreadsheet or smartphone notes app

Nice to have:

Why tracking works (short science + logic):

Control variables

Baking is an experimental process — keep flour, hydration, temperature, and starter percentage constant when testing one change so you can attribute results correctly [1].

Objective markers beat memory

Clock times, weights and temperatures are more reliable than impressions of 'felt like 2 hours' when diagnosing problems [1][2].

Patterns emerge

Repeated entries show how ambient temperature or a new flour changes fermentation speed, which lets you plan proofing and feed schedules [2].

Ingredients

For: What to record for each starter feed and bake

Date & time Record exact timestamps for feeding, mixing, bench rest and bakes
Weights Starter, flour, water and salt in grams using a [digital kitchen scale](https://amzn.to/4pUMVHi)
Temperatures Room and dough temperature with an [instant-read thermometer](https://amzn.to/49Xsgwp) if possible
Starter details Time since last feed, ratio (seed:flour:water), and whether it doubled or tripled in a [glass jar for starter](https://amzn.to/4pWAN8D)
Observations Bubbles, smell, rise %, tackiness, windowpane result, and final loaf notes
Photos Take consistent shots (jar side, dough top, crumb) for visual comparison

Step by Step

Set a minimal template → record each key stage → review patterns after 5–10 bakes

1

Create a simple template (10–15 min)

Make a one-page template in a notebook or spreadsheet with fields: date/time, recipe name, weights, temps, starter % and comments. If you use digital, keep a folder for images.

✓ Template exists and is quick to fill
💡 Keep it minimal. You must be willing to fill it out every bake.
2

Weigh and log at feed and mix

Weigh starter and feed using a digital kitchen scale. Log ratios (e.g., 1:2:2 seed:flour:water) and jar level before and after feed.

✓ Starter ratios recorded, jar photo taken
💡 Place jar against a neutral background for consistent photos.
3

Record dough temperature and bulk timeline

Measure dough temperature after mixing with an instant-read thermometer. Note folding schedule, times and visual change (rise % in a clear straight-sided container).

✓ Temperatures and fold times logged
💡 A single number for dough temp is worth more than multiple fuzzy descriptions.
4

Photograph key stages

Take photos: starter in jar (side-on), mixed dough (top-down), shaped loaf, final crumb. Use same angles and lighting where possible.

✓ At least one clear photo per stage
💡 Use your phone on a small tripod or consistent surface so comparisons are valid.
5

Log final bake parameters and sensory notes

Write oven temps, bake time, whether you used a Dutch oven or other method, crust color, oven spring, and taste notes.

✓ Complete bake record and crumb photo
💡 Note eating time and what you paired with the loaf — small context clues help later.
6

Review after 5–10 entries

Look for correlations: warmer kitchen = shorter bulk; certain flour = wetter dough. Make one controlled change at a time.

✓ A hypothesis for your next bake
💡 Keep changes to one variable (hydration, temperature, starter%) so you can attribute effects accurately [1][2].

What If It Doesn't Work?

Problems in recording usually come from inconsistency. Fix these quickly:

Missing or incomplete data

Likely: Template too long or inconvenient

Fix: Simplify template to essentials: weights, times, temps, one photo

Photos not comparable

Likely: Different angles or lighting

Fix: Choose fixed positions and background; photograph jar and dough from the same side each time

Too many variables changed at once

Likely: Making multiple adjustments per bake

Fix: Change one variable per bake and note it clearly; this is the core of useful experimentation [1]

Relying on memory rather than records

Likely: Delaying entry

Fix: Record immediately after key steps — a quick phone note prevents forgotten details

💪 Even imperfect records are better than none. Over time your log becomes an invaluable reference unique to your kitchen and starter [2].

What now?

You have consistent logs
→ Start controlled experiments (change hydration or starter %) and compare 3–5 bakes
You want to track starter health
→ Follow a feeding schedule and record rise times and smells
You want to diagnose a recurring problem
→ Use your log to isolate the variable and consult troubleshooting guides
You prefer visual learning
→ Compare your photos to examples and write notes on differences
