It's hard not to find innovative ideas when you look closely at what other retailers are doing. In many cases...it can simply be the "Why didn't I think of that" ones that are easy to implement and quick methods to improve upon current techniques. This display below was in the free coffee sample area at Trader Joes in Ardmore, PA. Using the beans themselves as a drip plate, this method shows the culinary aspect of the hot beverage inside the pump pot.
This display discovered in the Ardmore's Farmers Market featured mini wooden 2 quart farm marketing baskets lined with burlap and filled with raw beans. The window cling signage uses great culinary imagery to demonstrate the flavorings. This strategy seems to work, as I've seen many retailers focus on the ingredients in their packaging. One great example is Hagen Daz.
This method using burlap would allow use of almost any container as seen at McCaffrey's Market in Princeton, NJ. I personally would leave out the plastic liner,or have it down deeper in the container so it's not as distracting to the product.
I loved this poster from Ikea's Food Market area upon exit of their stores. The large format culinary imagery captures attention with a pertinent display underneath.
Just a few quick ideas on how to present coffee in compelling methods. Thanks for reading.
