We often get asked 'what's the difference between a strainer and an infuser'? The simple answer is - a strainer is like a sieve, you use it to strain or filter out the tea leaves whilst allowing the liquid to flow through to your cup, leaving you with a lovely cup of tea with no chunky bits to strain through your teeth. Whereas, an infuser is designed to hold your tea leaves in, without them escaping, and then be immersed in water to steep or brew for your desired length of time (like using a teabag), which varies depending on the type of tea you're drinking. Is one better than the other? Well that's up to you and how you like to brew your tea. The advantage of an infuser over using a strainer is it allows you to remove the tea leaves from the water at your convenience. This stops the tea from brewing further, as tea generally becomes more bitter the longer you steep it for. However, it's important to remember that your infuser needs to be big enough to allow your tea leaves to expand, as they inevitably do when the hot water is poured over them, as this will produce a better cup of tea.
