Learn the proper water temperature, steeping time, and technique to brew single-origin Japanese sencha, including Sencha Fukamushi, for a rich, sweet cup.

Quick answer

Brew single-origin Japanese sencha at 160-170°F (70-75°C) for 1-2 minutes using 1 teaspoon of leaf per 6 ounces of water. Adjust time for multiple steeps.

Why water temperature matters for sencha

Japanese green teas like sencha are delicate. Boiling water scorches the leaves, releasing bitter tannins and masking the natural sweetness. The longer steaming used for Sencha Fukamushi makes the leaf more porous, so it extracts quickly. Lower temperatures preserve the umami and grassy notes while avoiding astringency.

Choosing the right leaf-to-water ratio

Standard ratio is 1 teaspoon (about 2-3 grams) per 6-ounce cup. For a stronger brew, increase leaf amount rather than steeping longer. Over-steeping at any temperature can still produce bitterness. Single-origin sencha leaves are often whole and fluffy, so a teaspoon is a good starting point.

Step-by-step brewing guide

Heat water to 160-170°F (70-75°C): Boil fresh water and let it cool for about 2-3 minutes, or use a kettle with temperature control. Too hot and the tea will be bitter; too cool and it will be weak. If you don't have a thermometer, boil water and pour it into a cool cup, then wait 30 seconds before pouring over leaves.
Measure 1 teaspoon of leaf per 6 ounces of water: Place the leaves in a teapot or infuser. For Sencha Fukamushi, the fine leaf particles may settle at the bottom, so a wide-bottom pot or cup works best. Don't pack the leaves—they need room to expand and release flavor.
Pour water over leaves and steep for 1-2 minutes: Cover and let steep. Start with 1 minute for the first steep. Taste and adjust time for subsequent steeps. The leaves will continue to open. Over-steeping is the most common mistake. Set a timer to avoid a bitter cup.
Pour all the tea out of the pot: Remove the leaves from the water completely to stop extraction. Sencha leaves should not sit in hot water after steeping. Leaving leaves in the pot will make the tea bitter even if the initial steep was perfect.
Re-steep the same leaves 2-3 times: Add water at the same temperature and steep for 15-30 seconds longer each time. The second steep often brings out more sweetness. Each infusion reveals different flavor notes—don't discard the leaves after one use.

Product facts

Sencha Fukamushi: Sencha Fukamushi undergoes a longer steaming than most styles of sencha, bringing out a luxuriously rich aroma and a flavor that dances across the palate with sweetness in its wake. The deep steaming creates a fine leaf that releases flavor quickly, so you need a slightly shorter steep time and cooler water to avoid bitterness.
