The Lovely & Talented Roast Mistress thinks the label is 'beautiful' to quote her. No more beans necessary -- sorry Pink Rose -- beauty is in the eye of the beholder I guess.
If you're just selling the coffee in your own store no need for more info as you can tell the people what the coffee is but if you're selling bags of coffee through retailers then, based on my experience doing the same, I'd recommend the name of the coffee -- like Kenya, Ethiopia, XX blend, etc., so people will know what they are buying. Actually we have whimsical names for our coffee. Like
Buzz Bomb, Loco Leghorn, Barnyard Boogie (we're Red Rooster Coffee, thus the farm theme). And then we have one line of text underneath that saying what the coffee is, Double Roasted Colombian in the case of
Loco Leghorn; or what it will do, The You'll Never Sleep Again Blend! in the case of
Buzz Bomb.
Possibly the strength. That's big here in Ireland, people want to know how strong the coffee is on a 1 to about 5 scale (I've never seen a 1 by the way). Our coffees are 3, 4, 5. And then someone might want to know the weight, which I still need to put on the front of our label. We have it on the back and I assume people looking at the bag assume it is 227g to 250g, like all the other competing bags around it. For us adding the strength may be too much, too cluttered. I think our label is fairly crisp and clean looking right now.
Finally is the coffee ground or whole bean? For ground we don't do anything and for whole bean we have a whole bean logo we put on the front. Here in Ireland whole bean coffee is a specialty item so everyone knows the coffee is ground unless it says otherwise.
In someone else's store the bag's label does all the selling for you so you need to give people all the pertinent information they are looking for -- what is it, how much is it, how's it going to taste (strength) in one, quick, 2 second glance. That's about all the time you have. I guess you could ask yourself what would be the most important things the customers in your area would want to know about the coffee.
If you've got several coffees then color code the coffee (see below). That way when mom sends her eight year old in to buy a bag of coffee for her she can just say 'get the purple one' or 'get the black one'.
We have a back label with lots more details like brewing instructions (because in Ireland, a Johnny-Come-Lately country to coffee people need to know that). We have a bit more info about the coffee, and all of our contact information which is a labeling requirement here.
I'm sure there is more but the only other comment I've got, if you're retailing through other stores, is Shelf Space -- fight hard for shelf space about 4 to 5 feet off the ground. This is crucial! Where we are at that height we sell a lot more coffee than we do when we're higher up or lower down.
I'm sure there is a lot more to know from someone who has been trained in the art and science of labelling but that's what we've learned thru trial and error and listening to customer and store manager suggestions.
