An iced matcha green tea latte combines the vibrant umami richness of Japanese matcha with cold milk for a refreshing, energizing drink you can make at home in under five minutes. This Senbird Tea recipe uses ceremonial-grade Otome Matcha for a smooth, balanced flavor with no bitterness.

Iced matcha lattes from coffee shops often cost $5ā7 per drink and may use low-grade matcha green tea powder blended with added sugar. Making your own at home gives you full control over quality, sweetness, and cost. According to the Tea Association of the USA, matcha consumption in the U.S. grew by over 200% between 2015 and 2023, driven largely by the popularity of iced matcha beverages. A single serving of Senbird Teaās ceremonial-grade matcha costs roughly $1.50 when prepared at homeāa fraction of cafĆ© prices.
Matcha contains L-theanine, an amino acid that promotes calm, focused energy without the jitters associated with coffee. Research published in the journal Nutrients (2017) found that the combination of caffeine and L-theanine in matcha supports sustained attention and cognitive performance. This makes an iced matcha latte an ideal afternoon pick-me-up, especially during warmer months.


Use ceremonial-grade matcha. Culinary-grade matcha can taste bitter when mixed with just water and milk. Senbird Teaās Otome Matcha is stone-ground from first-harvest leaves in Uji, Japan, producing a naturally sweet, smooth flavor ideal for lattes.
Never use boiling water. Water above 80°C (175°F) scorches the delicate catechins in matcha and creates a harsh, astringent taste. Let your kettle cool for 2ā3 minutes after boiling.
Sift every time. Matcha powder naturally clumps due to its fine particle size (5ā10 microns). A stainless-steel sifter from our teaware collection takes 10 seconds and eliminates gritty texture in your finished drink.
Choose the right milk. Oat milk creates the creamiest result and complements matchaās umami notes. Whole dairy milk adds richness, while almond milk keeps calories lower. Coconut milk pairs well but can overpower subtle matcha flavors.
Make it a double. For a stronger matcha flavor, use 2 teaspoons (4 g) of matcha. This is especially helpful when using a lot of ice, which dilutes the drink as it melts.

You can, but the flavor difference is significant. Culinary-grade matcha is made from later-harvest leaves and has a more bitter, astringent profile that becomes especially noticeable in cold drinks without cooking or baking to mellow it. Senbird Tea recommends ceremonial-grade Otome Matcha for lattes because its naturally sweet, umami-rich flavor shines even over ice.
A typical iced matcha latte made with 1ā2 teaspoons of matcha contains approximately 60ā130 mg of caffeine. That is roughly equivalent to one cup of brewed coffee. However, matcha releases its caffeine more slowly due to L-theanine, providing sustained energy without the sharp spike and crash associated with coffee.
Bitterness in matcha usually comes from three sources: using water that is too hot (above 80°C), using low-quality matcha, or not sifting the powder before whisking. Always sift your Senbird Tea matcha, use water between 70ā80°C, and whisk thoroughly until smooth and frothy.
Yes. If you do not have a bamboo chasen, you can use a small electric milk frother, a mason jar with a tight lid for shaking, or even a regular fork whisked vigorously. A bamboo whisk produces the finest foam and smoothest texture, but any method that fully dissolves the matcha will work.
Store matcha in an airtight, opaque container away from heat, light, and moisture. Senbird Tea packages its matcha in resealable foil-lined bags designed to block light and air. Once opened, refrigerate the sealed bag and use within four to six weeks for optimal color and flavor. Matcha exposed to air and light will gradually lose its vibrant green color and develop a more bitter taste.
