How to Choose Green Tea and Matcha
Green tea can taste smooth and sweet or harsh and bitter. The difference usually comes down to the leaf and how you brew it.

Green tea: loose leaf or bags?
- Loose leaf usually has fuller flavor, because the leaves are whole or in larger pieces.
- Pyramid or sachet bags are a good middle ground for convenience.
- Standard paper bags often use broken leaf and dust, which brews faster and tends to taste more bitter.
Understanding matcha
Matcha is made from whole tea leaves ground into a fine powder, and you drink the whole leaf in your cup. That is why quality matters.
- Color: A bright, vivid green is a good sign. Dull yellow or brown powder is usually older or lower quality.
- Grades: "Ceremonial" is generally the smoother grade for drinking with just water. "Culinary" is meant for lattes, baking and smoothies. These terms are not tightly regulated, so reviews and origin help more than the word on the tin.
- Origin: Japan, and especially regions such as Uji and Kagoshima, is known for matcha. Check the country of origin on the label.
- Packaging: Small, airtight, light-blocking tins or pouches keep it fresher.
Brew it well
- Green tea tastes best with water that is hot but not boiling, roughly 160 to 180°F (70 to 80°C). Boiling water makes it bitter.
- Steep for one to three minutes and taste as you go.
- For matcha, sift the powder, add a small amount of hot water, and whisk until frothy before topping up.
Good to know
- Green tea contains caffeine. Matcha has more per serving than a standard cup of steeped green tea because you consume the whole leaf. If you are sensitive to caffeine, look at decaf green tea options.
- Store tea and matcha in a cool, dry, dark place in a sealed container, and use matcha within a couple of months of opening.
- Concentrated green tea extract in pills and capsules is different from brewed tea. Rare cases of liver injury have been reported, mainly with extracts, and extracts may interact with some medicines, so check with your doctor first if you take any medication.
- If you are pregnant, NIH advises keeping caffeine moderate and asking your health care provider. Caffeine also passes into breast milk.
