New Crumb Descriptor 'Alveolar Porosity With Trimodal Bubble Distribution' Added to Starter Dialect; Comprehensive Fermentation Taxonomy Now Exceeds 340 Terms

The addition was logged at 11:43am on a Tuesday. Margaret Osei-Bonsu, formerly a senior lexicographer on the third revised edition of the *Dictionary of Applied Food Science* (Blackwell, 2009) and before that a corpus analyst for the Oxford Advanced Learner's Dictionary expansion project, entered "alveolar porosity with trimodal bubble distribution" into version 4.7 of her Fermentation Language Repository with a definition running to 847 words and three hand-drawn diagrams, formally distinguishing it from "dispersed meso-bubble heterogeneity" on the grounds that the latter implies stochastic spatial arrangement while the former requires a statistically verifiable three-peak histogram of bubble diameter. She considers the distinction, she told this correspondent, "not subtle." The Repository, which Margaret maintains at fermentlexicon.substack.com alongside a parallel blog tracking linguistic drift across fifty bread-science texts published between 1960 and 2024, crossed 340 entries last month when she formalized the trimodal descriptor. The previous addition, filed in January, had been "reticular gluten scaffolding" — a term she coined after concluding that "web-like structure" appeared in twelve distinct texts with twelve incompatible meanings, a state she described as "terminological promiscuity" and "frankly embarrassing for a field with access to electron microscopy since 1981." Ferdinand — her 78% hydration levain culture maintained at 24°C in a 600ml Weck jar, named, one presumes, for de Saussure, though Margaret declined to confirm this — has been producing what she documents as "consistent open-structured macro-porosity with secondary meso-alveolar heterogeneity" for fourteen months. The distinction from trimodal distribution is, she clarified over a 40-minute call scheduled for fifteen, a matter of whether the crumb cross-section, when subjected to pixel-area analysis in ImageJ 1.53t, produces a bimodal or trimodal bubble-diameter curve. Ferdinand produces bimodal. A loaf Margaret baked last Thursday — 83% hydration, Renan wheat from a Normandy mill, bulk fermentation at 78°F for six hours and forty minutes, Dutch oven preheated to 500°F — produced, for the first time, a statistically clean trimodal distribution. She has begun the notation. (Renan, for those requiring orientation: a French winter wheat developed by INRAE for reduced fungicide dependency, descended from the cultivar Récital, itself traceable through four generations of postwar crossbreeding to a line emerging from Loire basin agricultural restructuring in the early 1950s. Margaret had verified this independently before purchasing the flour.) Her brother-in-law, who visited in February and described the loaf as "really holey," received, by text the following morning, a 600-word note distinguishing "open crumb" from "macro-porous crumb" from "alveolated crumb" and explaining that "holey," while colloquially functional, erases the spatial distribution data constituting the actual observation. He has not responded. Margaret interprets his silence as an instance of what she calls "passive terminological resistance" — a phenomenon she first documented in 2022 among her bread Discord cohort and which she is considering adding to the Repository as a sociolinguistic appendix. The blog traces how terms migrate across texts. She has documented "open crumb" appearing in Tartine Bread (2010) with no formal definition, entering amateur online usage by 2013 carrying three divergent meanings, and splitting into four distinct community-specific dialects by 2019 — a divergence she compares, with what she acknowledges is "some scholarly imprecision," to the vowel shifts separating Middle English regional dialects between 1350 and 1500. The comparison, she said, is structural. Not nostalgic. When asked whether 340 terms was perhaps comprehensive enough, Margaret was quiet for a moment. "I keep finding new loaves," she said. At press time, Margaret had identified a crumb structure in a bake posted to a Portland sourdough forum that she believes requires a new term — something to capture what she is provisionally calling "asymmetric lateral alveolar migration" — and had opened a new entry in the Repository. Her sister, who recently acquired a Dutch oven and a bag of whole wheat flour, used the word "bubbly" in a text message. A reply had been drafted.
