This Glossary serves as a technical archive.

It is designed to define the elements that compose this kitchen. I created this space to share the foundations of my craft.

It’s an invitation to look closer at the details, to respect the timing of the dough, and to find beauty in the simple, honest mechanics of baking.

To know the language is to truly enjoy the making.

Acidity Profile: The balance between lactic and acetic acids within a sourdough culture. It determines not only the flavor complexity but also the structural strength of the gluten network. A professional sourdough is managed to achieve a specific pH target.

Bacterial Symbiosis: The co-dependent relationship between wild yeast and lactic acid bacteria (LAB). In a stable starter, these microorganisms work in a self-regulating ecosystem, converting sugars into CO2 and organic acids.

Dormancy: A controlled reduction of microbial activity, typically achieved through refrigeration (cold storage). It is a strategic pause in the fermentation cycle, allowing for long-term maintenance without exhaustion of the nutrient base.

Feeding Ratio: The precise mathematical proportion of starter to fresh flour and water (e.g., 1:2:2). This ratio dictates the rate of fermentation and the timing of the peak, allowing for a disciplined schedule of production.

Hooch: A thin layer of ethanol and water that accumulates on the surface of an unfed starter. It is a biological signal of nutrient depletion and increased acidity, indicating the need for immediate metabolic intervention.

Levain: The portion of the starter that is off-shot and fed specifically for a final dough. Unlike the "mother" (the permanent culture), the levain is a one-time activation designed for a specific bake.

Microbial Activity: The rate at which microorganisms consume nutrients and produce gas. It is highly sensitive to ambient temperature and water quality, requiring a clinical observation of the environment.

Peak: The exact moment when a sourdough culture reaches its maximum volume and metabolic activity before the structural integrity of the bubbles begins to degrade.

Starter: The permanent, living archive of wild yeast and bacteria. It is the core biological engine of the kitchen, maintained through a cycle of consistent feeding and temperature control.
