Drinking coffee in excess, strong coffee or even dehydration may cause smell of coffee in urine. Coffee is a diuretic substance, which causes frequent urination. Coffee, tea, soda etc, contains a compound which is also a stimulant, caffeine. Caffeine is not metabolized by the body and is filtered out by the kidney. Most other drinks, such as orange juice etc are broken down into its smaller parts, into its constituent elements, when passed through the body. So, their smell does not appear in  urine the same way as they were ingested. Sliced chicken or turkey also gives odour to the urine as they are not metabolized when passed through the kidney. Different bodies have different metabolizing rate. It may vary from person to person. Some person can metabolize products easily and some cannot. This can also alter the degree of odour emitted out from urine. Caffeine is not metabolized and secreted out directly in kidney. The product is mixed with water so the odour is smelt freely due to the agitation of water. Colour ,odour and texture of secretions indicates what the body has consumed in the diet and the degree of product which the body uses and the remaining which it expels out from the body. There are some substances, which when ingested changes the smell of urine to a horrid smelling thing, completely different from the smell when they were ingested. Tea coffee etc should not be taken in excess but in a limited quantity.
