22 May The Complete Matcha Green Tea Guide

Ceremonial grade is the highest quality, intended for drinking straight with just water. It has the brightest green colour, the sweetest flavour and the finest texture. Culinary grade is processed for use in cooking and baking – it has a stronger, slightly more bitter flavour that holds up against milk, sugar and other ingredients. Drinking ceremonial grade in a latte is not necessary; culinary grade is the right tool for the job. 

A standard serving of matcha (approximately 2g) contains roughly 60-80mg of caffeine, which is similar to a small espresso. However, because matcha contains L-theanine, the caffeine is absorbed more slowly and the energy effect is steadier – without the spike and crash associated with coffee. 

You can, but the result will be noticeably different. A bamboo chasen creates the fine foam and smooth emulsification that defines a well-prepared matcha. A small electric milk frother is the best alternative if you don’t have a chasen. A metal whisk or spoon will not replicate the result. 

Store matcha in an airtight tin or sealed pouch, away from heat, light and moisture. Once opened, use within 4-6 weeks for best flavour. Refrigeration can extend freshness but introduce condensation – always let the tin return to room temperature before opening to avoid moisture damage. 

The most common cause is water that is too hot. Matcha should be prepared at 70-80°C; boiling water scorches the amino acids and brings out bitterness. The second most common cause is poor-quality matcha. If you are using good water temperature and still finding it bitter, the matcha itself may be low grade, old or poorly stored.

Yes, for most people. Matcha has been consumed daily as part of Japanese tea culture for centuries. The L-theanine helps moderate the effects of caffeine, making it gentler on the system than coffee. People sensitive to caffeine, pregnant women or those with certain health conditions should consult a doctor. As with any caffeinated drink, moderation is sensible. 

Shade-growing is the process of covering tea plants for three to four weeks before harvest. This forces the plant to produce more chlorophyll (giving matcha its vivid green colour) and more L-theanine (giving it its distinctive umami flavour and calm energy). Both ceremonial grade matcha and gyokuro use shade-growing; standard sencha does not. 

Look for vivid bright green colour (not dull or yellow), a single named origin in Japan (Uji, Nishio, Yame or Kagoshima), stone-grinding as the processing method, and a single ingredient list. Opaque, airtight packaging is also a good sign. Avoid products with vague labelling, matcha blends or artificial flavouring. 

Yes – culinary grade matcha is specifically designed for this. It holds its colour and flavour at higher temperatures and is priced appropriately for kitchen use. It works well in cakes, cookies, pancakes, ice cream, chocolate and lattes. Ceremonial grade is not necessary for cooking and is not the right choice for it. 

Morning is the most popular choice – the slow caffeine release and L-theanine make it a grounded, focused start to the day. A second serving around 1-2pm works well for the afternoon slump without disrupting sleep later. Most people find matcha taken after 3-4pm can affect sleep quality, though this varies individually.
