How to differentiate good beer from bad beer brewed using beer equipment. Beer is a popular alcoholic beverage among consumers, but do you know how to tell the difference between good beer and bad beer?
Check the color:
Observe the transparency and foam by pouring the beer into a clean, dry, colorless, and transparent glass. Light yellow beer should have a bluish golden yellow color, not dark. Yellow beer should be light yellow or greenish light yellow, preferably light in color and not dark brown. Dark beer should be dark red or dark brown, not light red or brown. However, all types of beer should be transparent, clear, shiny, without any suspended matter or sediment. For high-quality beer, when poured into a glass, the foam should be at least 3 cm in height, white and delicate, and last for more than 4 to 5 minutes before disappearing. Inferior beer has low foam height, light yellow and rough foam, no foam at all, or foams that quickly disappear.
Smell the aroma:
High-quality beer should have a distinct malt aroma and a hop-specific aroma. Inferior beer may have a less obvious malt and hop aroma. Poor quality beer usually lacks malt and hop aroma altogether, and may even have original, aged, or unusual odors.
Taste the flavor:
Take a sip of beer, let it sit in your mouth, and evaluate its taste and aroma. High-quality beer has a refreshing taste, with no strange or harsh flavors. Pale yellow beer, for example, is bitter and refreshing. Red beer starts with a bitter taste but leaves a sweet aftertaste. Dark beer has a robust and intense flavor. Inferior or bad beer not only tastes flat but can also have a bitter taste. Some beers may have a yeasty or unripe aroma.
