Soy sauce is a staple of Asian cuisine, but choosing the right bottle at the supermarket can be a daunting task. Salty, sweet, low-sodium, gluten-free tamari… Faced with an ever-expanding shelf, how do you navigate the options and make the right choice for your dishes?
As the editorial team's product expert, my mission is simple: to guide you. Forget the marketing jargon; this guide is designed to give you straightforward advice for choosing the soy sauce that's perfectly suited to your recipes and dietary needs.
Essential Criteria for Choosing Your Soy Sauce
Before we get to our top picks, here are the three key factors to check to ensure you make the right choice.
1. Intended Use: Which Dish?
This is the starting point: what will you be using it for?
- For sushi and sashimi: Opt for a sushi-specific soy sauce, which is often milder and less salty so it won't overpower the delicate flavour of the fish.
- For marinades and glazes: A sweet soy sauce or a robust classic version will be perfect for caramelising meats and vegetables.
- For everyday seasoning: A classic salted soy sauce, also known as shoyu, is an excellent all-purpose Asian seasoning for stir-fries, soups, or to liven up a simple bowl of rice.
2. Nutritional Profile: Low-Sodium or Gluten-Free?
A non-negotiable factor if you're following a specific diet.
- Low-sodium soy sauce: If you're watching your salt intake, many brands offer reduced-sodium versions without sacrificing flavour.
- Gluten-free soy sauce: Most traditional soy sauces contain wheat. If you have an intolerance, you must opt for a tamari sauce. It is brewed exclusively from soybeans, giving it a richer, denser flavour.
3. The Production Process: Natural Fermentation
The "naturally brewed" label is a true hallmark of quality. This traditional process develops complex aromas and a deep umami flavour, unlike industrial sauces produced by chemical hydrolysis, which often have a flat, artificial taste.

Frequently Asked Questions
What's the difference between light and dark soy sauce?
Light soy sauce is the most versatile. It's thinner and saltier, used mainly for seasoning. Dark soy sauce, which is aged longer and often has molasses added, is thicker, sweeter, and less salty. Its primary role is to add colour and depth to slow-cooked dishes like stews.
How long does opened soy sauce last?
Once opened, a bottle of soy sauce is best stored in the refrigerator, where it will keep for several months. While its aromas may fade slightly over time, it remains perfectly safe to consume. Refer to the date on the packaging and, as always, use your best judgment.
Can you substitute tamari for soy sauce in a recipe?
Yes, absolutely. Tamari can replace classic soy sauce in a 1:1 ratio in any recipe. Just keep in mind that its slightly richer, less salty taste may subtly alter your dish—often for the better.
