In general, craft beer is a non-pasteurised beer (which makes it less durable, but richer in aroma) brewed without the use of preservatives and using first-rate ingredients often from the local area.
In addition, craft beer, being brewed for a connoisseur audience, has non-commercial taste and aroma characteristics and generally expresses the personality and taste of the brewer who produces it.
We can thus enjoy many varieties of craft beer with very different flavours and aromas, and although the end result depends largely on the skill of the brewer, the concept of craft beer is often related to that of quality beer.
