Champagne production

The secondary fermentation of Champagne production is now carried out by immobilzed cell technology. Moet Chandon utilize a plug of immobilized yeast cells for bottle carbonation (Mensour et al, 1997). 

The yeasts used in the production of mead are usually strains of Saccharo-myces cerevisiae, similar to that used in wine, beer, and champagne productions. These yeasts metabolize sugars, such as glucose and fructose, resulting in the formation of ethanol and carbon dioxide. Nevertheless, the yeast Hansenula anomala had also given good results (Qureshi and Tamhane, 1987). 

More recent studies confirm the value of added ascorbic acid in wine for improvement of quality (680-683), in champagne production (684), in converting ordinary wine into sherry wine (685), in eliminating the need for heat sterilization of sulfur dioxide (686), and in the production of hot bottled Moselle wine (687). Reports on combined use of ascorbic acid and sulfur dioxide indicate its continued practical significance (688-691). 

This concept could be used in many other products, such as isothermal maintenance of fresh drinks (isothermal container for champagne, cava, wine, etc) and warm drinks (soups, tea, coffee, etc). 

Because proteins are involved in beer (Evans and Sheehan, 2002) and champagne foams (Senee et ah, 1999), and these are desirable properties, ultrafiltration is not a suitable treatment for these products. Adsorbents that indiscriminately remove protein are unsuitable for the same reason. 

The modem production of champagne is not so far removed from that empirically developed by the Benedictine monk Dom Pierre Perignon in the late seventeenth century. This method is also used outside...

The foam head created when beer is poured or dispensed, is an important aspect of consumer approval of a particular beer product. Compared with champagne foams, beer foams need to have different properties and be much more stable (beer foam needs to last for about five minutes). A cryogenic electron microscope image of beer foam is provided by Wilson [73]. Consumer preferences for beer foams vary, but can be characterized in terms of foam stability, quantity, lacing (adhesion to a glass surface), whiteness, creaminess (bubble texture), and concentration [852,853], As a result, much work has been done in order to be able to control these properties.

Back when they were the Newlyweds, Jessica Simpson and Nick Lachey also made the rounds at Royal Plantation. True to form, the shopping-crazed Simpson indulged in some local retail therapy. We had a local bazaar with products indigenous to Jamaica, says Royal Plantation managing director Jaime Stewart. Jessica spent 800 just like that The couple also indulged in the resort s C-Bar, a champagne-and-caviar hot spot where the Veuve Clicquot flows freely. ..
