History BC Beer, which dates back to 3500 BC and emerged in the Mesopotamian lands with its unique taste, has many forms.
The most important thing you need to know about beer freshness is that there are two things that will spoil the flavor of beer the quickest: Light and oxygen.
Beer is made from hops, which are extremely sensitive to light. Therefore, when exposed to light, the bitter components in the hops break down and react with trace amounts of sulfur components in the beer, causing it to taste bad and smell. Additionally, oxygen can change the taste of beer. Heat accelerates oxidation. Therefore, it is extremely important to store the beer under appropriate conditions to preserve its taste. We can say that a cool and dark environment would be the best choice at this point.
There is no doubt that kegging is the best way to keep beer fresh. You can experience fresh beer with a properly maintained keg. The vats are tightly sealed and pressurized, preventing light or oxygen from entering. But most of us don’t have a keg at home, so we buy aluminum cans or glass bottles.
Have you ever come across the phrase “skunk beer”? This occurs when light hitting the beer spoils the taste and smell of the beer. If you’ve noticed, most beer bottles are either brown, green, or clear. All three of these colors allow light to pass through, brown Bottles filter the light the most compared to green and transparent bottles.
Metal caps are used to close the bottles. The liner inside the cap ensures the bottle closes tightly. Twist caps, however, are known for allowing oxygen in. Same way Beers with cork caps also cause a very small amount of oxygen to enter the bottle, called micro-oxidation.
Aluminum cans offer the same protection as kegs. Aluminum is much better than glass at keeping out light and oxygen. It is extremely practical as it does not require anything while drinking and is easy to store. Some say they taste metal from these cans. This is a very rare situation because the inside of beer cans are coated with a special substance.
Do you know? More than 70% of our sense of taste comes from our sense of smell. This is one of the main reasons why people say draft beer tastes better. Since the glass brings the smell of beer closer to the nose during drinking, it allows the different flavors in the drink to be perceived better.
