When I brew a beer, I pluck a random shape or symbol from the air and scrawl it on the brew plan. That symbol then acts as an identifier for the beer. When it comes to bottling, I label each bottle with a small sticker that bares the same symbol. Previous examples include a black spot, a pink spot, dashed lines and a triangle. It's a low-tech solution to a problem that any home brewer will face.
With the aim of brewing a bit more regularly, I think it's about time I improved upon this. Above is a label I knocked up as an example. It's loosely based on the black IPA I brewed (which was identified by an asterisk), but only for the purposes of designing a label - it isn't the actual label! All future brews will be labelled in the above style, the information changing as necessary but the layout and design remaining the same. The box in the top left will give a nod to the old symbol labelling, whilst the extra information will make it easier when sharing the beer with other people, and keeping track of alcohol content and bottling date.
It's quite plain and simple; but I kind of like that. It'll make it easier to print and to re-design when I bottle a new beer. Below is an example on a bottle. What do you think?
