FAQ's

You'll find most green teas brew best at temperatures between 160-180°F in your kyusu, whether you choose a traditional clay pot or an iron alternative.

For ideal results, use roughly one teaspoon of tea leaves per 200-250ml of water, and store your kyusu in a dry place after cleaning it with plain water and wiping it thoroughly. Most kyusu teapots have a built-in filter to catch leaves while pouring.

Remember to avoid soap when cleaning, as it can damage the teapot's surface, and instead rely on gentle brushing for the spout and strainer areas.

Common Brewing Temperature Questions

Many tea enthusiasts wonder about the ideal brewing temperatures for their kyusu teapots. For sencha, you'll want to heat your water to 175°F (80°C), while other Japanese green teas may require temperatures between 160-180°F. You'll need to adjust both temperature and brewing time for optimal outcomes.

To achieve the perfect temperature, first boil your water to purify it, then use a yuzamashi or cooling pitcher to reach the target temperature. For sencha, brew your first infusion for one minute, with subsequent infusions increasing by 15 seconds each. If you're using cooler water, you may need to extend brewing times slightly. Just as with coffee brewing where final brew strength matters more than the exact brewing method, achieving your target temperature is more important than how you get there.

Remember that precise temperature control is essential – it directly affects your tea's flavor profile and aroma. Always check the specific brewing instructions for your particular tea variety.

Clay Vs Iron Options

When choosing between clay and iron kyusu teapots, understanding their distinct properties will help you make an informed decision.

Clay kyusu teapots, particularly those made from Tokoname and Banko clays, offer natural flavor enhancement due to their iron content, which reduces bitterness and enhances sweetness in your tea.

You'll find that clay kyusu come in both glazed and unglazed options.

Glazed versions prevent clay-tea interaction, maintaining the tea's original taste – suitable if you're conducting professional tastings.

Unglazed options allow the clay to interact with your tea, potentially improving body and sweetness.

While unglazed teapots require more maintenance to prevent unwanted flavor absorption, they excel at heat retention.

For ideal control over your tea's flavor profile, consider starting with a glazed kyusu before exploring unglazed versions.

Best Storage Methods

Proper storage extends your kyusu's lifespan and preserves its unique qualities, whether you've chosen a clay or iron model.

Before storing, let your kyusu dry completely for 48 hours, positioned upside down in a well-ventilated space to prevent mold growth.

Choose a tomobako (wooden box) made of paulownia wood for ideal protection against dust, breakage, and humidity.

If you don't have a wooden box, wrap your kyusu in acid-free paper or cotton cloth – never use plastic containers or paper towels that might off-gas.

Store your teapot in a dark, temperature-stable environment away from direct heat and sunlight.

For long-term storage, verify your kyusu is thoroughly clean and completely dry.

Maintain moderate humidity levels and proper air circulation in your storage area to protect your investment.

Cleaning and Maintenance Tips

Regular maintenance of your kyusu teapot guarantees its longevity and preserves the authentic taste of your tea. After each use, rinse with water to remove leaves and residue.

For daily cleaning, use hot water and let it sit for 1-2 minutes, but avoid detergents that can affect tea flavor.

For stubborn stains, you'll need to deep clean using salt, bicarbonate, or specialized bleach. Target the spout area with a cotton bud, and use a thin, bendable brush for hard-to-reach spots.

To prevent limestone buildup, opt for filtered water and avoid hot tap water with high mineral content.

Different materials require specific care. Handle ceramic kyusu with extra care, avoiding dishwashers.

Porcelain types are more resilient but still need gentle treatment. For unglazed kyusu, be particularly mindful of mineral buildup.

Ideal Tea Leaf Quantities

Now that your kyusu is clean and ready for use, understanding the right tea leaf quantities will maximize your brewing experience. For traditional sencha and bancha, use a 4g to 70ml ratio.

You'll want a kyusu that's 150-200ml to allow proper leaf expansion, as cramped leaves won't deliver peak flavor.

Consider your kyusu's shape when measuring leaves. Bowl-shaped vessels allow better leaf expansion than taller, vertical designs.

If you're using large-leaf teas, make sure your kyusu provides enough space for full expansion – leaves can triple in volume when wet.

You can adjust these ratios based on tea quality and personal taste. For precise control over steep time and strength, use a timer and consider pouring into a pitcher first, especially when serving multiple cups.
