All the above have merit- probably prefer #49 to this point but really close together makes it difficult to make a clear decision. Play with the colours . Maybe use a grinder or roaster as picture. Change the cup - make it more classical looking.
#49,#50,#51 all great and modern. maybe change the font/colour. Use coffee artisans and roasting since 1912. #81 #82- prefer 82 and again change up colours and font. iDEA IS VERY GOOD,
