Gyokuro Kombu Umami Broth
Shaded gyokuro brewed low and slow at 60°C with a sheet of kombu and a pinch of sea salt—a savory, mineral-rich sip that drinks like a gentle dashi.
Gyokuro is grown under shade for three weeks before harvest, which spikes its L-theanine and chlorophyll levels and gives the leaves their famous deep umami. Brewed at a very low 60°C, it tastes more like an elegant savory broth than a traditional green tea.
Pairing gyokuro with kombu seaweed leans into that umami profile. Kombu's natural glutamates amplify the tea's brothy character, and together they create a sip that lands savory and mineral in a way sweet tea never quite manages.
Temperature discipline matters here. Water above 65°C will pull out the leaf's bitter catechins and crush the delicate amino-acid sweetness. Use a yuzamashi or simply let boiled water rest 6–8 minutes before brewing.
Drink this mid-morning, in small cups. Gyokuro is one of the L-theanine-richest teas because of the shading, and it is not low in caffeine — level 3 of 3 in our catalogue, brewed at 60 °C so the leaf gives up its sweetness before its bitterness.
Ingredients
- 1 tbsp high-grade gyokuro leaves
- 150 ml soft water, cooled to 60°C
- 1 small piece of dried kombu (5 cm square)
- 1 thin slice of fresh ginger (optional)
- Pinch of fine sea salt
- 1/2 tsp white miso (optional, for a deeper broth)
How to make it
- 1Soak the kombu in the cool water for 20 minutes to extract its glutamates without bitterness.
- 2Warm the water gently to 60°C (do not boil — it ruins both kombu and gyokuro).
- 3Place gyokuro leaves in a small kyusu or teapot, pour the warm kombu water over them, and steep for 90 seconds.
- 4Pour into a small cup through a fine strainer. Add the pinch of sea salt and whisk in white miso if using.
- 5Sip slowly. Re-steep the same leaves twice more at 70°C for 30 seconds each — the second infusion is often considered the most savory.
