Provided is a beer-taste beverage, comprising less than 0.07 ppm by mass of diacetyl, and 0.4 (v/v) % or more and less than 1.5 (v/v) % of ethanol, having an H.sub.2S content of less than 5 ppb by mass, and comprising 50 to 1000 ppm by mass of lactic acid, or 50 to 1000 ppm by mass of phosphoric acid.

Provided is a beer-taste beverage comprising 1000 ppb by mass or less of 4-vinylguaiacol, and having an ethyl n-butyrate content of 140 ppb by mass or more, a ratio of the content (unit: ppb by mass) of ethyl n-butyrate to the content (unit: ppb by mass) of γ-nonalactone [ethyl n-butyrate/γ-nonalactone] is 23 or less.

A flavour composition comprising a compound according to the formula (I) or edible salts thereof, ##STR00001##
wherein R.sub.1 is alkyl residue containing 6 to 20 carbon atoms, or an alkene residue containing from 9 to 25 carbon atoms with 1 to 6 double bonds, R.sub.1 together with the carbonyl to which it is attached is a residue carboxylic acid, and NR.sub.2R.sub.3, in which R.sub.3 is H or together with R.sub.2 and the N-atom to which they are attached, a 5-membered ring, is a residue of an amino acid, in particular proteinogenic amino acid, ornithine, gamma-aminobutyric acid or beta alanine, or a 1-amino cycloalkyl carboxylic acid.

The present invention relates to the use of a yeast protein extract to stabilise the haze or cloudiness of a drink, particularly beer and preferably white beer.
