The reason why wine tasters swish the wine around in their mouths is to get the taste. Both the front and the back areas of the tongue contain taste buds, although neither one has any distinct sensation in taste. Taste buds can detect food and liquid that is bitter, salty or sweet, without a problem. Science has proved over the years that aging is actually a chain of chemical reactions that occur over time. Depending on the temperature, the chemical reactions can either be good or bad. Chemical reactions all have unique energy factors that need to be met for each individual reaction to happen. If the temperature isn t right, the chemical reactions in the wine won t occur. Once a few weeks have gone by, the riddler will slant the bottles to a 60 degree angle and ensure that each and every bottle on the riddling rack is neck down in the proper hole. Once the riddling process is complete, the Champagne bottles will be placed in a freezer for a brief period of time. After an ice plug has formed along the necks of the bottles, they will be placed on a conveyer belt and taken down the line to a disgorging machine that will remove the crown caps from each one of the bottles. Once the grapes have been collected, they are gently pressed, in order to collect the running juice only. The temperature creates the frozen water crystals, which are fermented along with sugars and the particles that are found in the free running juices. Through this process, the wonderful and rare ice wine is created. The grape is a result of the Pinot and Croatian Blanc grape, which are extinct to this day. Chardonnay on the other hand is still popular, fermented and aged using oak barrels that help to bring out the vanilla flavor the wine is well known for. It can also be aged and fermented using bottles, although it won t age quite as much as red wine.
