Some may refer to the color as honey causing some extra reading, but most refer to the taste. One that popped out that I agreed with was Arturo Fuente Hemingway series. For that matter, I find most cigars with a Cameroon wrapper somewhat on the sweet side.
Try the advanced search with sweet, sweetness or other similar words. Good luck.
