Duteurtre Y1 - 1994/01/01 UR - http://www.ajevonline.org/content/45/4/407.abstract N2 - The relationship between base wine filtration and Champagne wine foam number is described. Using artificial viewing equipment foam quality is shown to be adversely affected when base wines are passed through a 0.2-µm filter. Better foam parameters were obtained with 0.45-µm filtration. It is suggested that Champagne foam quality is influenced by particles or macromolecular complexes that improve or worsen foam behavior. ER -
