Without editing, censoring or deletion, transcribe your story, describing where you were, the emotions and symbols that help someone visualize and feel the roots of your brand. Then read what you've written, selecting the adjectives and nouns. These should link directly to your products features, benefits and attributes and give you the basis of your backstory.
This back story can be the message on your label. For Brooks Reitz, of Jack Rudy Cocktail Co. and producer of a concentrated tonic syrup, his label carries the almost unedited family story of his grandfather, Jack Rudy. The characteristics of Rudy's life drove the product's intensity.
When you've done these five things, you have captured the essence of your story, the core of your message just as these entrepreneurs have done. And just as these entrepreneurs have done, use them as the building blocks for your brand.
