So You Want To Know How Scotch Is Made


Scotch whisky takes a significant amount of time to produce. It really is a tedious process that can last for years. Nevertheless, when it's crafted in the correct way, the product is one that's worthy of the wait.

Initial, the barley is immersed in tanks of water for roughly 72 hours. The moisture causes the barley to begin the germination process. Once germinated, the barley will then be moved to the malting section of the distillery where it is placed into drums also known as the malting floor.

The aim of the germination process is to turn the starch in the grains into fermentable sugars. The yeast will process the sugars creating alcohol in the fermentation phase. Turning the barley regularly assures the temp will stay consistent. Wooden shovels referred to as sheils are utilized to turn the grains on a traditional malting floor. The grains will die if the temps gets above 71 degrees F. This would thus halt the entire process as the starch will not be converted to fermentable sugars.

The grain is kiln dried to halt the germination process and the continuation of sugar consumption. Usually, a traditional kiln is often a building standing two levels tall with the top perforated permitting all heat to escape. The first floor contains peat bricks which are burned. During this procedure the grain is dried and absorbs the peat aroma and taste. The pagoda roof design on a distillery is a very distinct characteristic. Today, the majority of the distilleries purchase all their malt from a central malting company. Then again, there remain a small selection that continue to be traditional and do everything themselves.

The grain is milled into grist and combined with water in mash tubs. The mixture is heated to 60 degrees. During the mashing period the water is changed at least four times to remove sediment. The result of this mashing is called wort. The wort needs to be cooled off before combining with yeast. This huge container is never filled totally since wort froths quite a bit because of co2. By the time two or three days have passed, all of the yeast is killed from the ethanol it released. The ultimate product of the cycle is termed wash. It has 5 to 8 percent alcohol.

The stills where the wash is placed are created from copper and are regulated to a special shape which allows for proper distillation to occur. Distillation is usually carried out two times, however, some distillers do it 3 x or more. Just after the entire process is finished the distillate will be put into kegs made of oak, for a at least 36 months. Having said that, many Scotch whiskies are aged for longer.
