Yeast extract foliar spray elicits divergent aroma-phenolics profiles in 'Cabernet Sauvignon' and 'Marselan' grapes and wines.
Article in Food chemistry: X, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Foliar sprays of yeast extract (YE) at 1.67, 2.5, and 5 g/L were applied at 5 % véraison and again 10 days later to 'Cabernet Sauvignon' (CS) and 'Marselan' (MS) grown in eastern China. The 5 g/L YE treatment increased total norisoprenoids by 28 % in CS berries and by 82 % in MS, yet GC-MS quantification of 77 volatiles and OAV-based sensory reconstruction revealed contrasting effects: CS wines lost 29-42 % of ethyl isobutyrate, ethyl 2-methylbutyrate, ethyl acetate, and geranyl acetone, flattening fruity and floral perceptions, whereas the same esters increased 46-55 % in MS wines, intensifying ripe black-fruit notes. Anthocyanins responded divergently as well: four anthocyanins in CS skins rose 15-52 %, while five in MS declined 20-85 %. CIELab color metrics and partial least-squares regression confirmed concentration-dependent hue shifts. These findings support a targeted, cultivar-specific strategy for tailoring red-wine style and aroma structure under the terroir conditions of eastern China.
