When we create a new beer, we consider bitterness, sweetness, colour and ABV which is the alcohol percentage (%).
From time immemorial, beer has always consisted of three standard ingredients:
However, with just these three ingredients, beer would be sickly-sweet and dull, so brewers have always added flavourings such as heather, flowers, spruce tips, borage, bog myrtle, herbs or spices.
It was not until the 15th century that brewers discovered hops, and beer, as we know it, was born.
Hop flowers contain resins which impart bitterness and aroma and, as a bonus, act as a preservative – extending the life of the beer.
