Introduction
There are thousands of different styles of beer in the world today but the one thing they all have in common is that the brewing process has been the same for 4,500 years (Papazian, 2003). The steps are basic: clean the equipment, make the wort, ferment, and bottle. There are many books on brewing beer and they are exhaustive with theory. This being the case, the fermentation process, and the bottling will not be cover herein. By following these simple instructions, anyone can make the transition from Beer Lover to Beer Aficionado. As I was once told, it takes beer to make beer. So grab a beer and let us get started.
Equipment Needed
Inspect your equipment for cracks, leaks, chips, etc. Ensure your equipment is safe for use and sanitized properly.
• a 20 qt. brew pot (large canning pot)
• large stirring spoon (non-wood)
• ordinary table spoon
• timer ( a clock will work)
• measuring cup (preferably Pyrex glass)
• fermentor (food-grade plastic bucket or glass carboy)
• airlock (get from homebrew shop)
• sanitizer (Iodine concentration)
• thermometer
Preparation
1. Assemble ingredients. Gather the ingredients for the brew. A kit usually consists of malt extract, yeast, and hops. The extract may already be "hopped" and the kit may not include any hops.
2. Clean and sanitize.
***Note***
It is not recommended to use chlorine bleach to sanitize the brewing equipment. Bleach makes a great sanitizer but corrodes many metal brewing parts.
It may seem strange, but the most important thing in brewing is cleaning and sanitization. Clean all equipment and then sanitize it in an iodine solution with the exception of the brew pot, wort chiller (if available) and the spoon. Sanitization will occur for these items during the boil. The homebrew shop sells a great iodine concentration for this or medical iodine is a suitable substitute. Make a sanitizing solution and allow these items to soak. To make this solution, add one tablespoon of iodine concentration for every gallon of water.

Making Wort
Wort is what brewers call the sweet, amber liquid extracted from malted barley that the yeast will later ferment into beer.
1. Boil the brew water. In the brew pot, bring two gallons of water to a boil. Pour this water into the fermentor and leave it to cool.
· Add 2g of yeast to the water and add sugar (1g, 2g, …up to 5g).

Mendel wrote that genes are passed from parents to their children and can produce the same physical characteristics as the parents.
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...
This is because the theory suggested that the traits would be more common through generations if the environment did not make it less common. In other w...
The Hardy-Weinberg principle states that throughout generations, genetic variation will remain constant if kept from the presence of disturbing influences. The principle can be described as an idealized or equilibrium state. Due to the fact that in nature, genetic mutations and the environment certainly impact the genetic variation of a system.
In a 100ml beaker place 50mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved.
Introduction: Genetics is the study of how genes and heredity combine to create traits in living organisms. Gregor Mendel disproved the theory that heredity comes only from parents. He discovered that there were dominant and recessive genes and his “Law of Dominance” has been used to selectively breed plants and animals for particular attributes. It has also been successfully adopted to identify the risk of passing down genetic diseases. Francis Galton took Mendel’s discoveries further by studying multifactoral inheritance and discovering ‘blending traits’, also known as continuous variation. With these traits, involvement of a wide range of genetic and environmental factors results in the creation of wide-ranging genotypes.
Genes are expected to give offspring hereditary similarities to the parent. However, this was not known and Gregory Mendel asked himself what was passed on by parents to their offspring that is the basis for similarity. Mendel would go on through experiments with pea plants to answer short questions. The answers were short as well as to say that the passing of characteristics from parents to the offspring is throug...
After choosing the flavor that best suits your taste buds, the second step is making sure that your kitchen houses some necessary equipment for making the Kool-Aid. Find a two-quart pitcher. Plastic is nice, but glass pitchers allow the liquid to shine through and add festive coloration to any refrigerator shelf. Next, find a long-handled wooden spoon, a one-cup measuring cup, a water faucet that spouts drinkable water, usable white sugar, and an ice cube tray full of ice. Then, you are ready to mix.
It is impossible to set a date as to the first time fermentation was performed. It is possible, however, to guess, and this guess is roughly 8,000 years ago. Wine has been written about for centuries, in the Greek and Roman myths and scriptures. The Greek god of wine, Dionysius, was in charge of the fermentation atop Mount Olympus. The people of this time may not have known exactly what they were doing, but it was a somewhat complicated procedure. The crushing of grapes, and the storing of their juices led to an amazing beverage that is still used in current society. This process of fermentation was used throughout the time of early Christianity, and other religions, for purposes within sermons. Throughout the Renaissance, fermentation was used in the making of wine as well as bread, not to mention new medical applications. Fermented products were brought to America along with the new settlers. With new government, though, America was put into a prohibition, which did not last long. Today, fermentation processes are carried out nearly perfectly, without too large of variations among the products.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
Gregor Mendel was an Austrian monk who revolutionized our understanding and perception of genetics. Mendel’s experiments in his monastery garden provided future geneticists with the basic principles of hereditary through the experimentation in both hybrid and pure bred pea plants, which he found to follow specific patterns in their offspring. The choice to use peas was because of their distinct varieties and their ability to produce offspring quickly and the ability to easily regulate fertilization simply with the use of a paintbrush. When conducting these experiments Before Mendel Pea Plant Experimentation it was commonly accepted that a child’s genetic traits were simply half from the mother and half from the father. This evidence was supported by experiments were generally conducted over a short period of time resulting in skewed and unreliable data, whereas Mendel’s experiments were conducted over an eight year period involving tens of thousands of plants. Two of Mendel’s traits that he focused on were the texture of the seed pod. E.g. smooth and round or wrinkled. In the first generation of these plants 100% of the pea plants possessed the Smooth and round texture. On the second generation of the pea plants of every 4 pea plants 3 posessed the smooth trait and a singular pea plant produced wrinkled seeds. Upon the review of his results Mendel concluded that characteristics could be expressed through dominant and recessive traits. The Dominant trait masks or completely covers the recessive, whereas a recessive gene is an allele that is only present in a homozygous genotype. Through Mendel’s experiments he proposed three principles of inheritance, whether you are looking at humans or pea plants, the apparent genetic traits t...
The Brewing Industry is a global business that produces and sells beer, with more than 133 billion litres of beer sold per year and revenues of $294 billion dollars in 2006. In 2015 there was a 12.8% rise in craft beer sales in the United States, with the craft beer market worth $22.3 billion dollars (The Brewers Association, 2015). The Brewing Industry is made up of numerous multinational companies that annually produce hundreds of millions of beer barrels, and just in the United States sells over $100 billion dollars in beer per year (Beer Institute Annual Report, 2014). In the United States, the individual who is in charge of the production of beer is known as the Brew Master. From 4% to 6% (abv) is the common strength
Alcohol is a class of organic compounds that is characterized by the presence of one or more hydroxyl groups (-OH) attached to a carbon atom. Alcohol was unknowingly produced centuries ago when fermentation occurred to crushed grapes (Pines, 1931). In today’s society alcohol is produced for the use of household products such as varnishes, cleaning products, but is more commercially important in the liquor business. A chemical process called fermentation accomplishes the production of ethanol, the alcohol or liquor. From there, the ethanol goes through distinct processes to become the dark and clear liquors on the store shelves.
