Which type of container offers the least protection against skunking?

Cans
Brown bottles
Green bottles
Ceramic bottles

The correct answer is: Green bottles

Green bottles offer the least protection against skunking due to their inability to block light effectively. Beer skunking occurs when it is exposed to light, particularly ultraviolet (UV) light, which can lead to the formation of off-flavors due to a chemical reaction with the hop compounds in the beer. Brown bottles provide better protection than green bottles because they filter out a significant amount of light. They are favored for packaging light-sensitive beers. Cans offer the best protection, as they are completely opaque and shield the beer from all light, reducing the chances of skunking to nearly zero. Ceramic bottles, while also not transparent, are less common for beer packaging, but typically provide adequate protection against light. Therefore, green bottles, which allow more light to penetrate compared to the other options, are most susceptible to causing beers to skunk.
