Although I mostly use a kyusu (such as this one), sometimes I’ll use an infuser too. It’s convenient and easy to clean.
The disadvantage is that with one infuser you can’t brew tea for several people at the same time.
How does the infuser type impact the flavor of tea?
One thing to take into consideration is the particle size in your chosen tea. Fukamushi sencha, for example, has many tiny particles. If your infuser has openings that are too wide, it won’t filter at all!
Now imagine that you will brew your fukamushi sencha with an infuser with very fine openings, but the surface area is quite small. What will happen? Basically, the infuser gets clogged quickly and you won’t get much flavor.
Tea leaves expand when brewed. For best results, your infuser should be big enough to let the tea leaves expand freely.
Experiment: infuser basket vs infuser ball
My infuser basket can hold a decent volume although it’s not intended for a mug, but for a yunomi (Japanese teacup) instead. By the way, make sure that you know the diameter of your cup before buying an infuser basket 🙂
The infuser ball I selected is slightly smaller and has few openings. This is an extreme comparison, I want to clearly tell the difference after brewing.
I’ll be using sencha leaves, because it’s the most common Japanese tea. The general guideline is to use 4 grams of sencha, 60 ml of water (2 oz), 1 minute of steeping and a water temperature of 70 °C (158 °F).
I first measured the 4 grams of tea leaves to place in each infuser. I’m using a kitchen scale to have an exact measurement, but you don’t have to. It’s about 1 teaspoon.
Then I measured the water volume with a measuring cup, heated it until the correct temperature (measured with a thermometer) and then poured it into the cups with the infusers in place.
After 1 minute, I took out the infusers and tasted each tea.
The taste of the tea was notably different. The infuser ball didn’t really allow much of the flavor to be released, it has a bland taste. Almost like if I had used too much water.
Regarding the infuser type, I’m not saying that infuser balls are bad for brewing. Some infuser balls work just as good as infuser baskets.
It also depends on the tea that you’re brewing, kukicha will brew well in the infuser ball used in this post. Why? Because the twigs and stems don’t expand much when brewed.
What type of infuser do you use? Tell me in the comments.
