Step1
Decide how you're going to use soy sauce. Some people use it as a dipping sauce for dumplings or vegetables. Some use it as a cooking ingredient, especially in glazes.
Step2
Read the label on the bottles of soy sauce the supermarket sells. Find one with the least amount of sodium if you intend to use it raw. Buy one with the highest sodium content if you want to use it in cooking.
Step3
Examine the label to see how long the soy sauce was aged. Choose the sauce that was aged for the longest time because aging produces superior flavor in soy sauce.
Step4
Find a Japanese soy sauce. The Japanese manufacturers use pure mountain water and ferment the soy mixture in cedar barrels for a long time, producing a more flavorful sauce.
Step5
Buy a more expensive brand of soy sauce rather than the best-selling market brand. Pricier soy sauces taste better because their manufacturers brew them slower and longer than the less expensive brands.
Step6
Test several different brands. Simmer each separately in a medium-sized soup pot until the sauce turns to a glaze. Taste each to determine which has the superior flavor. Use this sauce when cooking glazes, such as Teriyaki.
