What's different about the coffee - taste, texture, mouth feel?
It's stronger (we enjoy strong, dark coffee), and much more of the flavor emerges.
We've often read reviews of coffee that use the word "fruity." We had no idea what the reviewer was talking about 'til we had pressed coffee.
We used to by Starbucks French Roast, but found a perfectly suitable (and less expensive) substitute in Millstone French Roast. It's available at Sam's Club in 2-1/2 lb. bags. I highly recommend it.
