Yes, the colour of beer bottles can significantly impact the taste

Yes, the colour of beer bottles can significantly impact the taste—thanks to science, not just style. Here's how:

The Enemy: UV Light
Beer is sensitive to light, especially ultraviolet (UV) rays. When exposed, a chemical reaction occurs between UV light and hops (specifically isohumulones), producing a compound that smells like a skunk. Brewers call this “lightstruck” beer.

Brown Bottles: The Best Protectors
- Block most UV rays, keeping beer fresh longer.
- Preserve flavor and aroma by preventing chemical reactions.
- Widely used in the industry for their superior protection.

Green Bottles: Aesthetic Over Function
- Offer less protection than brown bottles.
- Became popular during WWII due to brown glass shortages.
- Still used today for branding and tradition, despite higher risk of skunky flavor.

Clear Bottles: The Wildcards
- Provide no UV protection unless specially coated.
- Allow consumers to see the beer, but risk flavor degradation.
- Some modern bottles use UV-blocking coatings to compensate.

Bonus: Cans
- Offer 100% UV protection.
- Chill faster and are great for outdoor use.
- Increasingly popular among craft brewers.

So next time you're choosing a brew, remember: the bottle isn’t just a container—it’s a flavor guardian.
