The answer to the title's question is in the last paragraph of the article. > What is an effective technique for examining how many papillae someone has in a given area of the tongue? All of them involve darkening it, and the most enjoyable is to swirl red wine in the mouth and over the tongue. If done correctly, you will be able to see little lumps of tissue on the tongue that are the papillae. Next, take a piece of three-hole notebook paper. The punched holes are about 6 or so millimeters in diameter, and a piece of paper torn off with one of these holes can be placed over the darkened tongue. Now simply count the number of papillae you see in the punched hole. If you have fewer than 4 papillae, you are more than likely a nontaster, whereas from 4 to 8 papillae would suggest that you are a taster. Anything over 8 would indicate that you are a supertaster or a super-supertaster.
