TESTING AND REPORTING OF SUGAR IN WINE HARMONIZING EXPRESSION OF MEASUREMENT RESULTS IN WINE ANALYSIS Gallo produces amazing wines in every category, to suit every taste.  Gallo also imports wines from nine wine growing countries in the world.  Gallo’s wine portfolio totals over 60 unique brands: Barefoot is the number 1 wine in the US and has introduced many new wine drinkers to the wine category. In 2011 alone we updated the Bella Sera Label and updated the Redwood Creek Label. Last year we also introduced The Naked Grape from California and Bodega Elena from Argentina.

Recommended Definitions Reducing Sugar: - Sugar with an aldehyde or keto- group (for example glucose, fructose and the pentoses, for example arabinose) -Does not include sucrose -Should not be confused with reducing substance Residual Sugar:-All fermentable sugars including sucrose plus pentoses Reducing Substance: Includes glucose and fructose, plus oligosaccharides, and other reducing matter (such as tannin and Polyphenols) Non-fermentable Carbohydrates: These include pentoses, polysaccharides, (and pectins, tannins, pigments, all of which may interact with carbohydrates to form complexes). Note that the first 3 definitions above are all abbreviated ‘RS’ although they represent different meanings. The term residual sugar with reference to wine is understood to mean the sum of glucose, fructose (redcing sugars) and the non-rducing sugar, sucrose.

Conclusions and recommendations for future work This Work Group has carefully considered the complexity of analyzing and reporting for sugar in wine. Based on the arguments presented in this Technical Brief, the following is recommended to reduce technical barriers arising through requirements for sugar testing in wine: Clarify the meaning of the abbreviation ‘RS’ when used, since it could stand for residual sugars, reducing sugars, or reducing substances, which have different meanings. Include sucrose in the total sum of wine sugar when the term ‘residual sugar’ is used. Use methods that are specific for wine sugars. Avoid testing for sugars not common in wine. Use standardized units for reporting wine sugars, for example report in g/L.
