The page was about Dairy Products: http://en.wikipedia.org/wiki/Dairy_product
I would have added that there is an organization, the Future Farmers of America, that has a competition specifically over judging Dairy Products and Production. This event is called a "CDE" or Career Development Event. The competition includes a multiple choice test over milk facts and production. There are also questions that need to be solved mathematically using special formulas. The rest of the competition is on judging. The competitor rotates around a room completing each sections and recording their answers. One section is over milk. There are 10 samples that must be tasted. For each sample the competitor must determine if there is a defect (acid, bitter, feed, foreign, garlic/onion, malty, oxidized, rancid, salty, unclean, flat, no defect) and then assign the defect a score based on its severity. The score ranges from 1-10 with 1 being most severe. Another section is identifying cheeses (blue, brick, brie, cheddar both mild and sharp, colby, cream, edam/gouda, monterey, mozzarella, munster, processed American, provolone, swiss ). There are 10 samples and the competitor is allowed to taste each and identify it correctly. Another section is determining between natural and artificial dairy products. Milker Units is another section. The competitor must examine equipment used in a Dairy facility (without touching it) and identify its defects and their severity. There is also a section where you observe 6 slides that have different amounts of sediment and the competitor must record a score depending on the amount present. The last section covers the California Mastitis Test. The competitor must run this test on eight samples of milk and record the scores depending on the severity of the results.
