The article “Chemistry of Winemaking: A unique Lecture Demonstration” by L. B. Church of the State University of New York, seeks to demonstrate how the winemaking process can be used as a teaching tool. Found in the Journal of Chemical Education, the text uses an instructive and formal tone while discussing the process and how it might relate to the classroom. His rhetoric leans heavily toward the use of logic. Aimed for chemistry teachers, the article refrains from using step-by-step demonstrations of each and every process, and instead discusses the use of common techniques that could be used within the framework of Winemaking. By guiding the readers through the general process, the author makes it seem a logical and easy to implement demonstration that would capture and maintain the interest of students. He does this with a noticeable lack of appeals toward pathos and ethos, and indeed, there are absolutely none of the tried and true tools of persuasion. I believe this is a deliberate act on Church’s part to accommodate his discourse community of chemists. The community has little interest in how someone may feel about any given subject, and instead desires the facts behind that subject so that they may draw their own conclusions. The discourse community is interested in what you started with, what you did with it, and what you observed during and after the process. Then, and only then, should the conclusions derived from that information be given. Even after having done so, a writer in the scientific community must be prepared to be proven wrong, as that is the nature of science. As such, attempts to persuade via emotion tend to be ineffective, and would often be better spent presenting your arguments, and so I feel that the ...

...how useful the demonstration would be in a classroom. The author’s tone is formal and academic in nature, without heartfelt appeals or attempts to persuade by emotion.
In the span of only a few pages, L.B. Church has given us an overview of the winemaking process. He has done so with sufficient detail for those in the chemistry community to follow along, yet still in a cursory enough manner as to not bog them down with the unnecessary. Written as if it were the procedure of an experiment, he has given enough information for the experiment to be repeated, tested, validated and improved upon. And that is almost assuredly his goal from the very beginning, as it must be for any published author in the chemistry community.

Louis Pasteur had been studying fermentation to explain why dairy and meat was going bad. He didn’t believe that it was spontaneous but rather there had to be a scientific explanation. When working with grapes and understanding that yeast was the driving agent in fermentation of grapes, he hypothesized that if you can protect grapes from fermentation, that people could be protected from infectious disease.
The name for the process of fermentation comes from ‘fervere’, the Latin word meaning “to boil”. Early observers of the process assigned this name to it because as fermentation occurred in barrels containing crushed grapes, being used to create wine, bubbles were produced making it appear as though the mixture were boiling. Yeasts have been secretly creating alcoholic (fermented) beverages since ancient times in Asia, Egypt, Babylon, and many other early civilizations. However, no one knew what made the process work and what made the creation of such fermented beverages possible. When people think of traditional wine makers, it is not uncommon to picture someone standing in a large bucket mashing up grapes with their feet. These ancient wine makers realized that for some odd r...
Add all the ingredients, without the leaven of wine to the mainstreaming vessel. Seal up with fermenting airlock.
He highlights the importance of the diversity in drinks by a clear interpretation of the 6 drinks of the world: Beer, Wine, Spirits, Coffee, Tea, and Coke. Each drink marked a new era and became symbols of beliefs in the nations they greatly impacted. Wine and Beer were both the first developed. Beer was made from wheat and barley. “The mouth of a perfectly contented man is filled with beer”.(Standage’s 303) This caused humanity to shift more to the agriculture life and become more static. This resulted in the increase in technology and caused different cultures to become more stable. “To rich and poor alike hath he granted the delight of wine, that makes all pain to cease”. Euripides (Standage’s 48) Wine was brought to many religious ceremonies. Wine is very sacred because only small amounts of it where able to transported due to the expense. The king was able to test his power and will due to selling major quantities of Wine. Both Beer and Wine started first phase in human modernization. The author also explains how coffee and tea made a huge impact on human history. He viewed coffee as a way to purify the brain. Tea is made of evergreen bushes which is used as a healing substance in Chine.
A History of the World in 6 Glasses is divided into separate sections based on the different beverage representing a key historical era. Starting about 10,000 years ago, beverages began to have other purposes than just to quench thirst. Beverages were used medicine, currency and for religious purposes. The first historical beverage presented by Standage is beer. With beer he shows how processing grains led to the development of agriculture, as well as migrations, and the creation of civilizations in Egypt and Mesopotamia. The accidental fermentation of grains into beer was “magical” creating a beverage which induced a state of altered consciousness. It was seen as a gift from the gods and used as a religious offering to thank...
In the 1976’s American wine, industry had forever changed. France has been the leader thought the winemaking world for centuries. This movie “Bottle Shock” is based on a true story of California wine makers on their first milestone of the winery industry. The wine industries in California show the world that the French is not the only credible wine producers. The movie helps us to see the significance in wine culture had a change not only the French opinion of Americans, but the entire world’s opinion had changed. I will explain the meaning of the movie along with significant details that happened to become the reason how American wine will rival the French wines and changed the world.
This shows that collaborating with people can become very productive especially when it comes down to life or death. My island depended on people coming to class in order to communicate to one another and ensure our survival.
Robert Mondavi built a state-of-the-art winery that became a premium winemaking facility as well as conveying a unique sense of Mondavi wines to the visitors. Soon the new winery became a place where the best practices in the production of premium wines were developed, eventually establishing the standard in the wine industry. Robert Mondavi was the first winemaker who assembled experts with various back¬grounds in the fields of viticulture and winemaking to give advice on the new wines. He also developed new technology that allowed special handling of grapes and the cold fermentation of white wines. Furthermore, Mondavi's company created process innovations, such as steel fermentation tanks, vacuum corking of bottles, and aging of wines in new French oak barrels. Dedicated to growing vines naturally, Robert Mon¬davi introduced a natural farming and conservation program that allowed enhanced grape quality, environmental protection, and worker health.
Wine quality is an inherently subjective matter which is used as a reflection on the chemical composition of wine itself (Factors Influencing Wine Quality, 2001). Wine quality is in regards to the compound that the taster associates with pleasurable experiences which is defined in various ways. The ‘ideal’ wine is dependent upon its nearness to a specific target wine, depending on the nearness of its composition to that of a higher wine, however it can also be defined in ways such as is harmonious complexity (in reference to the characters, tastes and aromas produced by the wine and the combination which they produce) or its inharmonious notes (which centres the concept of the importanc...
By selecting this chosen commodity I hope to further my knowledge in my field of study and work. I believe by having an open mind and being constantly exposed to new and old ideas personal progress can always be made. This will help me to understand the ever-changing industry and provide a solid foundation into my introduction to the Australian grape growing and wine industry.
The older the wine the costlier it sells. Most of the wines are stored in wooden barrels, as it enhances the taste and colour of the wine.

Grape juice gets its flavour from the sugars, organic acids and phenolics, while the vitamins, minerals
There are literally hundreds of compounds in a glass of red wine. As wine ages the number of compounds change into more complex molecules, then add to that the effects of oak compounds. Don't take the value and complexity of wine too cavalier. This drink has been around since the beginning of civilization and until about 1960 we did not know the health benefits and the magic of wine. In fact, the discovery of resveratrol did not come about until

Throughout the course of this Investigation, how sugar influences the rate of fermentation and how this in turn, affects the overall quality of wine was explored. Three wines were produced, each with varying sugar levels. The Investigation was designed so that one wine had a fairly low sugar content; one had an ideal sugar content and one had a high sugar content. After the fermentation process stopped, a taste test was conducted in order to assess the quality of the wine. The taste testers were blindfolded in order to reduce the chance of biased opinions. Each taste tester not only sampled each wine, but also sugar water and tonic water. This enabled the validity of the results to be assessed. It was found that the majority of the conclusions drawn by the taste testers were legitimate.
The wine industry first began in Canada in the early 1800’s when European grape varieties were grown. Unfortunately, the Canadian climate was not able to sustain these varietals and over the following century, only the native Canadian grapes were able to survive. Throughout this time, Ontario was able to develop its wine industry through exports to be one the largest in North America. To better regulate...
