The grape varietal commonly known as “prosecco” or more traditionally known as “glera” is used to produce a fruity‚ simple‚ and refreshing sparkling wine that comes form northern Italy and is called “prosecco.” The steep slopes of northern Italy lead to the production of a light and fruity bubbling wine‚ often compared to champagne. The areas of Italy that are known for the production of prosecco are Valdobbiadene and Conegliano‚ which are part of the larger region of Veneto (Mionetto Prosecco

Ministry of Higher Education Oman Medical College Health Science Program By: Marwa Rashid Al-Flaiti Objectives: To fined the rate of fermentation of the apple and carrot juices‚ and compare their rates to each other. Introduction: Procedure: A 5.00 ml of apple juice was taken in a clean 150 ml conical flask and diluted with 50 ml of distal water. Then‚ 2.00 grams of Baker’s yeast and 5.00 ml of solution of Pasteur’s salts were added to the above conical flask. The content of flask

THE CONTINUOUS BREWING OF BEER Beer is produced commercially by the controlled fermentation of wort‚ a liquid rich in sugars‚ nitrogenous compounds‚ sulphur compounds and trace elements extracted from malted barley. Fermentation is the process by which glucose is converted to ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the

DESCRIPTIVE WORDS FOR WINE Wine tasting‚ as a production control technique‚ depends upon converting into words the impression created by the reaction of the wine on the taster ’s palate. In order that one wine‚ tasted by several individuals‚ be reported in the same way by each‚ it is necessary that all of the tasters use the same words for the separate palate impressions the wine creates. The terms used in sensory examination fall naturally under the four headings of appearance‚ color‚ taste

Wine Making Science or Art? 12320 Dan Simonic Wine. Science or Art? Wine is an art form perfected and refined by the utilisation of scientific methods and concepts. This concept of science refining the artistic merit of wine can be displayed in many areas of wine making however the points in particular interest are‚ the picking of the grapes which is considered to be the pinnacle fine wine‚ the chemical and yeast content added whilst the wine is being created and‚ most importantly

Louis Pasteur And The Alcoholic Fermentation Abstract: Louis Pasteur (1822-1895) was a French chemist and microbiologist known for his discoveries in the field of vaccination‚ pasteurization and microbial fermentation. His discoveries have saved many lives and his contributions to science‚ technology‚ and medicine are nearly without precedent. This paper will focus on one of the aspect of his work that relates mostly to chemistry: the alcoholic fermentation. Louis Pasteur:

food‚ enjoyed across the globe‚ conveys health benefits through lactic acid fermentation. The fermentation process can transform the flavor of food from the plain and mundane to a mouth-puckering sourness enlivened by colonies of beneficial bacteria and enhanced micronutrients. While fermented food like yogurt‚ sauerkraut and kefir are well-known many other lesser-known foods also benefit from the lactic acid fermentation process. Indeed‚ virtually every food with a complex or simple sugar content

There are more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide

An experiment to demonstrate the effect of temperature on fermentation by yeast The purpose of this laboratory is to observe how temperature affects the metabolism of Grape juice by visibly noting the volume changes of identical food mixes containing yeast at different temperatures. Background Information If yeast is added to a liquid containing sugar and other nutrients‚ kept at an appropriate temperature (and deprived of oxygen)‚ it will turn the sugars into ethanol (alcohol) and carbon
