Four-time Oscar-nominated Director David Lynch is famous for movies such as Mulholland Dr. and The Elephant Man, but people may know that he also has a line of signature coffee blends.

"And I really like it very much," he says.

This possum coffee is not made from droppings of animals like some of the world's most expensive blends.

The bags are available for purchase on an online store run by his family.

The Aerosmith drummer has been doing more than just rockin'. Kramer first launched the coffee line in 2012, after his search for the perfect brew fell flat.  While on a break from Aerosmith's summer world tour, Kramer has been hard at work hitting the presses with Comfort Foods in Massachusetts to seal his very first retail partnerships with area grocers. Kramer's expertly developed line of sustainable coffees (two dark roasts from Sumatra and Ethiopia, and a "Dark-Medium" roast hailing from Guatemala) will be available in mid-August at all Roche Bros. and Dave's Fresh Marketplace locations.
