The beer style "Porter" in general were very popular with porters. Since I didn't really know what a porter was before this research, here is a quick summary on what a porter is and a little history!
This beer style was developed in the British Isles during the 18th Century (according to Hornsey, 2013), this brown beer style contains a generous amount of hop content, and considered extremely robust as it has a long shelf life compared to other beers in this time. It was favoured as it could be brewed without high quality malt, long shelf life and improve in flavour over time. (Rabin & Forget, 1998)
The beer label, is used for many reasons and the main one is to provide insight to the consumer on what the beer they are buying is. Using the article as an example,
Brand name - G. Sleeman
Class & Type - Porter
Address - Silver Creek Brewery, Guelph, ONT.
The beer label is also a marketing tool, it should look appealing to catch the consumers eye and make them want to buy it and try it.
