BrewNotedOur approach Sencha water temperature: how to find your starting point
Read the tea’s instructions, measure one brew and compare a small temperature adjustment.

Use the tea’s own instructions first
Sencha instructions vary with the tea and the supplier. Hibiki-an recommends 80°C water in its sencha guide and discusses a cooler 70°C preparation for a softer impression in its broader brewing guidance. Those are supplier recommendations, not a universal temperature rule for every green tea.
Temperature is only one part of the recipe
Before experimenting, write down leaf weight, water volume and steeping time. A temperature comparison is hard to interpret if the second cup also contains twice as much leaf. Use the same water source and brewing vessel for both attempts. If the seller gives a recipe for several servings, scale the leaf and water together rather than changing only one of them.
Make a baseline cup
Choose the instructions on the packet as your first recipe. Measure the water near the point of brewing: a kettle setting and the temperature after transfer need not be identical. Start the timer consistently and separate the brewed tea from the leaves when the steep is finished. Save the recipe before deciding whether you enjoyed it.
Plan the next comparison
If you want to investigate a gentler cup, try a modestly cooler preparation while keeping leaf, water and time unchanged. Compare at similar drinking temperatures. Write down whether the change affected aroma, intensity or your preference. A weaker cup is not automatically an improvement, and bitterness alone cannot identify the cause.
Treat later infusions separately
Previously steeped leaves are a different starting condition from dry leaves. Record the infusion number and follow the supplier’s guidance for subsequent steeps. Do not compare a first infusion at one temperature with a second infusion at another and attribute the entire difference to temperature.

Know when to stop adjusting
A useful daily recipe is one you enjoy and can repeat. If the baseline works, keep it. You do not need to chase a perfect number or buy another kettle simply to make the record more elaborate. This guide offers a comparison method; it does not report a blind tasting or laboratory extraction analysis.
