Sunred®, a botanical extract-based biostimulant, enhances polyphenols accumulation and improves quality of musts

SUNRED® is a biostimulant produced by Biolchim SpA containing phenylalanine, methionine, monosaccharides, and botanical extracts rich in oxylipins: naturally occurring compounds involved in several ripening-related processes. SUNRED® has been shown to improve fruit color, ripening uniformity, and soluble sugar content in apple, cherry, grape, melon, and tomato. In the present study, SUNRED® application in grape (‘Cabernet Sauvignon’ and ‘Prosecco’) was shown to increase accumulation of antocyanins, polyphenols and sugar content in musts without altering acidity and other quality parameters
