Matcha and matcha lattes are caffeinated. Several ready-to-drink greens in the results are labeled non‑caffeinated. Because formulations vary, check individual product labels if you need exact caffeine amounts or want to avoid caffeine.
Fresh green beans are sold prewashed and trimmed, ready to eat or steam-in-bag for easy meal prep. They are presented as ready-to-use with no preservatives listed.
Many ready-to-drink greens are packaged in aluminum cans, and at least one premade matcha almond‑milk latte is packaged in PET (polyethylene terephthalate).
