Taste Test Experiments

For my taste test experiment I decided to do Starbucks vs. Dunkin’ Donuts. I am a bit of a coffee fanatic. I can always been seen with a Starbucks or Dunkin Donuts coffee in hand at least once a day. So for my experiment I decided to do my taste test experiment to compare to the two companies coffee brands. I went to Starbucks and got a Venti Caramel hot coffee with crème and then went and got a large Dunkin Donuts caramel hot coffee with crème. I decided that my sorority house is where I knew I could find plenty of willing people to participate in my blind taste test experiment. The first taste test I did was the triangle taste test. In this test I make 2 small cups of Starbucks coffee and 1 cup of small Dunkin Donuts coffee for them to try. Due to the fact that I am such a coffee fanatic I can tell the difference and figured that everyone else would be able to do that same. I was extremely surprised when several 3 of my 6 friends had chosen one DD and Starbucks coffee as being the same brand. Next, I did a paired comparison, where I put one drink in one cup and the other in the other cup. A majority actually preferred DD coffee to Starbucks. But the answers were all over the map when you asked them which coffee was which brand. Many people were unable to identify the difference between which was Starbucks and which was DD. One friend stated that she believed that Starbucks has a much bolder coffee taste compared to the more mild coffee taste of Dunkin Donuts. After doing the two Taste Test Experiments I have come to the conclusion that even thought people say that they only drink or prefer a certain brand, if you do a blind taste test they may not be able to identify the difference in the two competing brands.

    Coffee Annotated Bibliography

    They identified 9 cohort studies of coffee consumption and risk of type 2 diabetes, and utilized both the SAS MIXED Procedure for meta-regression analysis and the Log-RR as the dependent variable. These models yielded that of the 17,438 participants, higher coffee intake was consistently associated with lower amounts of newly detected hyperglycemia. These models it supported the hypothesis that habitual consumption is associated with a substantially lower risk of type 2 diabetes. The methodologies used are very detailed, leading credibility to the work performed. This supports my supporting point that coffee may prevent Parkinson’s disease.

    Roaring Fork Beer

    To start, we must understand that the approach to the brand is different for non-users and ex-users. Non-users have possibly never tried our product, whereas ex-users have but have rejected it. Building awareness of our product to non-users may be necessary. Conversely, ex-users are all aware of our product but do not have an affinity for Roaring Fork Beer. Furthermore, we must identify whether the reason our product is rejected is sensory or perceptual. The case, there is a great deal of supportive evidence that leads us to believe the insight is sensory. Describing the taste as “chemically, gassy, bad and flat” are descriptive and tangible. Since our targets dislike the taste, we have the option of investing in either changing the sensory of our target or accommodating them by changing the taste. While changing the taste may attract these nonusers, we risk alienating our current users and potentially losing brand equity. Creating a sister product may also risk brand identity, while marketing would be problematic because ex-users would associate the old taste to the sister brand. Overcoming that barrier would be expensive. However, there are some qualities identified by these nonusers that we can build on to overcome the disposition towards our product. The main attributes to our advantage are: a) “It’s the beer that I prefer when I am out drinking” b) “It is reasonably priced” and c) our target identifies a drinker of RFB as a working man that is a common laborer. We can thus build a campaign that centers on a beer consumed in a social outing by hard-working individuals. We could focus on neighborhoods in Colorado so as to avoid alienating our current client base who identifies well with that geographic region. We can focus on increasing sales to current consumers and use their influence to spread desirability of our product. Concurrently, since 70% of our customer base is 40 or older, challenging their taste selection can be viable. The idea is that as one…

    Pepsi Coke Challenge Lab Report

    ABSTRACT: A blind taste test is used as a tool for companies to see how they can improve their product. My Biology 141 class challenged people to do the Pepsi/Coke challenge to see if they were cable in distinguishing between Cola products Pepsi and Coke even if they had recently brushed their teeth or not. There were two hypotheses to test. The first one being that there is a difference between brushing your teeth and not brushing your teeth, within the last thirty minutes, in their ability to distinguish between Pepsi and Coke. The second one was that there is no difference between brushing your teeth and not brushing your teeth, within the last thirty minutes, in their ability to distinguish between Pepsi and Coke. After doing the test and performing the necessary calculations on the chi-squared test, I found out that a greater amount of people who brushed were able to correctly identify the cola products.…

    Chemistry of Coffee

    Before coffee is roasted, it is referred to as “green coffee”. The green coffee is primarily made up of caffeine, lipids, carbohydrates, proteins (amino acids), and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase, and it is the carbohydrates, proteins, and acids that will undergo significant reactions during roasting to produce coffee. The important groups of carbohydrates in beans are from the monosaccharides and the polysaccharides found in beans. The disaccharide Sucrose (C12H22O11) also plays a vital role later on in coffee. Generally speaking, Monosaccharides represent the simplest forms of sugars, such as glucose and fructose, and usually follow the formula Cx(H2O)y. These sugars serve as building blocks for polysaccharides like starches and cellulose, which are usually long repeating chains of a basic unit or monosaccharide. All together, carbohydrates represent about 50% of green coffee’s base. Amino acids are present in green coffee at levels of about 10-13% of dry matter. Amino acids are molecules containing an amine, a carboxylic acid group (an organic acid that contains at least one carboxyl group of COOH) , and a side chain (a chemical grouping that is attached to the main group and is specific to each compound). Lipids represent around 11-17% of coffee. They do not play a huge role in the chemical processes of creating coffee- rather, they act as conductors of aroma and taste later on in the coffee process. Caffeine, an astringent stimulant, develops in coffee as a defense mechanism in the coffee plant. Its content remains stable throughout roasting and brewing. It is highly water soluble. Finally, green coffee beans contain numerous acids. Chlorogenic , Citric, Phosphoric, and Quinic Acids represent some of the most important acids in the green coffee bean. A small amount of acetic acid…

    Ice Cream Survey

    We had a balanced amount of men and women mostly between the ages of 20-30, partake in our survey. However there was a wide range of age from 15-60. Almost all of our applicants were originally from South Dakota, Nebraska, or North Dakota. We did have a few people from California and from Arizona. Almost all of our applicants enjoyed breakfast food with 38 people. They usually buy ice cream in the summer, but 25 still stated they bought ice cream on a monthly basis. Almost everyone said they buy ice cream both at the store, and at ice cream stores like Dairy Queen. 43 of 44 applicants said they preferred to go to a place like Dairy Queen than the grocery store. $3-4 was the overall average that applicants said they would spend on ice cream at a retailer. $5-6 was the average spent at a grocery store. Applicants were about even when it came to the size of the container. We learned that frozen yogurt was a bad idea because almost everyone preferred ice cream over frozen yogurt. A small amount of 10 people looked at the nutrition facts on ice cream. Only 2 people preferred and ice cream with no sugar added. 23 applicants said that they buy the same flavor of ice cream every time. While 21 like to try new flavors of ice cream. It was a very close race between one solid flavor or multiple flavors. The majority was multiple flavors. Another thing that was interesting was the amount of applicants that stated that they like extra toppings on their ice cream. More than twice as many consumers eat ice cream out of the dish rather than the cone. 25 of out applicants said that they eat breakfast daily. 10 said 3-4 times week, and 7 said less than 2 times a week. Over 80% of our applicants agreed that they found ice cream enjoyable. The same amount liked the taste of bacon. About 60% said that nutrition was important to them. About 70% enjoyed the taste of maple syrup. Over 60% were willing to try new foods.…

    Precis on Placebo Effects of Marketing Actions

    Marketing action is one of the most influential factor in dominating the consumer’s buying preference. In this reading, the effect on the consumers were tested based on their perception and experience of a product. This creates a placebo effect on the behavior of the respondents’ expectation that were informed of a product at a discounted price against with those of purchased at the regular price. The marketing action focusing mainly on the given price altered the effectiveness of a product due to the consumer’s belief and impression. This was proved to happen in an unconscious manner with which occurs automatically upon hearing of the price difference. An experiment was conducted to further prove of this study. For the first variant, the product was introduced as cheaper compared to its original price and was anticipated that the respondents’ result would be less effective for them though actually the same product was given on both sides. On the other experiment, and exposure to strong advertising claim was greatly influenced; upraising the effect that greatly present a positive result. It is believed that the consumers’ beliefs and expectations are influenced in making thier judgement of a product. The relationship between the price and objective indications of quality product is directly connected to each other. This means that a product with lower price is associated with lower quality. One concrete example mentioned is the test on giving an energy drink that inreases the mental activity of a person. Those of which who were informed to be bought at a discounted price would less likely be able to solve problems thus, would only be able to finish fewer puzzle problems. Also, those product encorporate with a favorite brand label would gain more preference than those of unlabeled or generic one. Similarly, optimizing a product of putting “75% fat-free” sign is better than the indication of “containing 25% fat.”…
