Matcha is a finely ground green tea powder made from tencha. When you prepare it with water, you drink the dispersed tea powder rather than steeping leaves and taking them out. That difference explains the opaque green appearance and why a bowl of matcha feels different from a clear cup of brewed green tea.

What makes matcha different from other green tea powders?
The key word is tencha, the leaf material used for matcha. Its production involves shade-grown tea leaves that are steamed and dried without rolling before grinding. The Japan Matcha Association distinguishes powdered tencha from powdered sencha.
Grinding sencha into a fine green powder does not make it the same ingredient. Likewise, a tea bag containing sencha and matcha is a blend with its own brewing instructions. Both can be enjoyable drinks, but the names tell you something different about what is inside the packet.
Whisked powder is different from steeped leaves
With ordinary loose-leaf preparation, water extracts flavor from the leaves and the leaves are then removed. With matcha, whisking distributes fine leaf particles through the water. Think of a suspension, not sugar disappearing into a clear solution. ITO EN’s introduction to matcha explains the distinction between drinking the powdered leaf and brewing tea leaves in water.
This also changes what the equipment is doing. A tea strainer normally keeps loose leaves out of the cup. A sieve used before whisking matcha helps break up dry clumps; it is not intended to remove the matcha from the finished drink. The whisk then brings powder and water together.

What does matcha taste like?
Expect a green, vegetal character, with savory umami and varying amounts of bitterness or astringency. There is no single flavor shared by every tin. Some matcha tastes fuller and mellower, while other products have a sharper edge. Astringency is the drying sensation in the mouth, rather than simply another word for bitterness.
Milk changes the balance again. In its latte guide, Ippodo distinguishes its lighter, more astringent matcha from richer varieties with more body. Added sweetener changes the drink further. If your first taste was a sweet café latte, plain matcha whisked with water will be a different comparison.
Read the ingredients before choosing a tin or pouch
Start with the product format and ingredients, then read its preparation directions. A green package or the word matcha on the front does not tell you whether you are buying plain powder, a sweetened mixture or a tea blend. ITO EN’s Matcha Green Tea range, for example, includes sweetened and unsweetened powders as well as tea bags combining green tea and matcha.
Plain matcha powder: choose this when you want to control the amount of tea and decide separately whether to add milk or sweetener. Check that the ingredient description identifies matcha rather than only saying powdered green tea.
Sweetened matcha mix: follow the directions for that mixture. A spoonful contains more than tea, so substituting it spoon-for-spoon in a recipe written for plain matcha changes the result. Check for sugar and any other added ingredients before deciding how to use it.
Sencha and matcha blend: check whether it comes as tea bags, loose leaves or powder. A blend designed for steeping is a different purchase from a tin intended for whisking. Flavor descriptions and serving photographs are useful clues, but the ingredient list and directions are more specific.
Usucha, koicha and lattes are different preparations
Usucha is the thinner, drinkable preparation of matcha and water. Koicha uses proportionally more powder and less water to make a much thicker preparation, as shown in Ippodo’s koicha guide. A matcha latte adds milk or a plant-based alternative to prepared matcha. These names describe ways to serve the tea, not three interchangeable ingredient lists.

One producer’s example for a first bowl
For a concrete usucha example, Ippodo’s published method calls for sifting 2 g of matcha, adding 60 mL of water at 80°C (176°F), then whisking vigorously for 15 seconds in an M-shaped motion. These are that producer’s instructions, rather than a universal ratio for every powder or drink.
If you are assembling the equipment, you can browse bamboo matcha whisks and fine-mesh sieves on Amazon. Check the bowl opening and sieve dimensions so the pieces work together.
Choose the preparation first: plain powder and water for tasting the tea itself, a latte for a milk-based drink, or a labeled mix for its intended convenience. Then match the package to that choice. This is more useful than assuming every product with matcha in its name will behave the same way.
