People have been brewing and consuming beer and ale for centuries although no one is exactly sure, when beer was discovered. Since its origin, the brewing process has been refined into a modern science. Beer consists of four essential ingredients which categorizing a beverage as beer. The four ingredients are water, malt, yeast and hops. The brewing process may vary between breweries for different flavors, colors and levels of alcohol but the reactions of the general process remain the same. The first procedure is to form a base for the beer, which is simple add water at desired temperature. Malting is the next stage in this series, it occurs when the desired grains are added to the base, the grain must remain in the water long enough to begin germination or sprouting of the grain. There are several different types of grain that are used such as wheat, rye, and oats, which are used in different flavors of beer. This produces starches, which begin to break down to sugar through the release of their enzymes. The grain is then heated, which stops the process of growth and prevents flowering. After the liquid has been malted, yeast is added to the base. Yeast is added to dissolve the malt sugar and it expels carbon dioxide. This occurs because yeast is a live culture. The last element key to the process is adding hops. A hop is a plant used to bitter the beverage, which gives it that “beer flavor.” This process can take up to seven days to properly ferment or longer. For ale brewing beer must be keep in warmer condition for a shorter period and for lager, it remains in colder conditions for a couple of weeks. If each batch is not brewed to a uniform standard then all the way to the time of consumption it can mildly or greatly affect the taste.
PURPOSE OF THE STUDY
The claim to this experiment is that a subject could not differentiate between draught and canned beer. Each beer assumedly was brewed to the same uniform standard i.e. Miller Lite. Although, each beer is brewed differently a few other variables may or may not contribute to different a taste. Handling of packages maybe different because draught beer is stored in an aluminum keg, which contains much greater volume, which could potentially have more carbon. As opposed to a can, this is typically stored in a case among many cases on a palette. Both of which are typically handle by machines until the consumer directly handles the package.
I began my experiment by first choosing a control tester, which I chose my father. I chose a place to conduct the experiment, which would be exactly the same location for each test. Another control measure in the place setting was to ensure the tap in which the draught beer was dispensed was clean and most importantly the same each pour. During the course of the experiment, the same bartender poured each glass and opened each can. Some people may believe the way you pour may affect the taste. Everyone cleans their tap...
