It is very important that the label for your beer is unique and showcases your product to the best light so that you have atleast a upper hand when it comes to advertising your product.
For this, the first step in designing the label would be to do a bit of research on the labels of your competitors and come up with a design that is totally different form the others. Also, it is important to showcase your beer, for which offering a free tasting session would bring you a lot of buyers, if they like what they are seeing as well as tasting.
