References, 596 Malolactic fermentation (MLF) in wine is a secondary fermentation that usually occurs at the end of alcoholic fermentation by yeasts, although it sometimes occurs earlier. It is practically a biological process of wine deacidification in which the dicarboxylic L‐malic acid (malate) is converted to the monocarboxylic L‐lactic acid (lactate) and carbon dioxide (Davis et al. 1985). Deacidification is particularly desirable for high‐acid wine produced in cool‐climate regions, such as New Zealand and Canada. This process is normally carried out by lactic acid bacteria (LAB) isolated from wine, including Oenococcus oeni (formerly Leuconostoc oenos; Dicks et al. 1995), Lactobacillus spp. and Pediococcus spp. (Wibowo et al. 1985). Various technologies, such as bioreactors with high‐density cells and immobilized cells or enzymes, have been developed to facilitate wine deacidification (Maicas 2001). Oenococcus oeni is the preferred species used to conduct MLF due to its acid tolerance and flavour profile produced. In addition to its occurrence in wine, MLF occurs in other fermented beverages, such as cider (Carr 1987; Jarvis et al. 1995).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
