I have before. I think it mostly depends on where you are hunting like anything else.

If you hunt " suburban deer" then I think it is likely not to spook these kind of deer. As opposed to deer in the rural Mountains Tthat are more sensitive to those kind of odors. The former is the kind of deer I mostly hunt and I have brought coffee in the stand before without seeing the white flags.

Whether or not ole mossy horns never came around because of it I cannot say. But I can say that during the rut those big boys don' t really care and if some coffee is going to enhance your hunt then bring a big jug of it with ya!
