Myth four: If you want the best results for your home brewing beer, you should bottle it using green bottles only. Absolutely false. Believe it or not, brown bottles work the best because they are better equipped to keep out the most dangerous culprit to your homebrewing efforts – light. Due to a shortage of brown glass in Europe during the 20th century, green glass was used more frequently and it was incorrectly assumed the beer was of a better quality. Truth is, exposure to light is an excellent way to dash your efforts and spoil a good batch of beer.
