The International Bitterness Units or IBU is one way to measure how a beer tastes in terms of bitterness. While the bitterness of beer plays a significant role in a flavor profile, it is only one of many factors. Alcohol content, malt and water quality, yeast fermentation byproducts, bacteria, and aeration also affect a particular beer's taste profile.
Back in the day, we're talking all the way back to the 90s and prior, the case of beer was the definitive unit of measurement for starting a good time.
Good branding is a cornerstone of any business. Craft beer drinkers want to know your brewery's mission, they want to be part of your community, and they want the artisanal stature of your beer to show up in your physical artwork, including your cans, your taproom walls, and most importantly, your brewery logo.
