Same shop, same rough season, totally different cup. That's the kind of thing people email us about, and nine times out of ten the answer isn't roast or grind, it's cultivar. Once you start paying attention to it, a lot of the why does this taste like that questions start answering themselves.
What cultivar actually means here
Cultivar just means the specific variety of tea plant the leaves came from, the way Gala and Honeycrisp are both apples but taste nothing alike. For matcha, cultivar affects three things you can actually notice in the bowl: sweetness (driven by amino acids like L-theanine), color (chlorophyll content, which is also why heavy shading matters so much), and how the powder feels once it's whisked, some cultivars foam up thick and cling to the sides, others go thin and quick. It also affects how forgiving the plant is to grow, which is why some cultivars show up everywhere and others only in small batches.
We use three across our different grades: Yabukita, Okumidori, and Saemidori. Each one earns its spot for a different reason.
Yabukita: dependable, a little grassy, the workhorse
Yabukita is the cultivar most of Japan's tea fields are planted with, for matcha and otherwise, because it grows well in a wide range of soils and doesn't ask for much. On its own it leans grassy and a bit brisk, with more bite up front than the other two. Shaded properly and ground fine, it turns clean and reliable rather than sharp. It's the cultivar in our everyday grade, the one meant for lattes and baking where you want real matcha flavor without it taking over the whole cup.
Okumidori and Saemidori: rounder, sweeter, harder to grow well
Okumidori buds later in the season and tends to come out a deeper, more saturated green with a softer, rounder mouthfeel. Less of that grassy snap, more of a gentle vegetal sweetness that sits on the back of your tongue after you swallow. It holds up under longer shading periods, which is part of why it ends up in our higher grades.
Saemidori is the fussiest of the three to grow (lower yield, more sensitive to timing) but it's also the one that tends to win people over who say they don't usually like matcha straight. High in amino acids, low in bitterness, with a color that's noticeably brighter green even before you whisk it. It's the cultivar behind our ceremonial-grade tin, and it's honestly the one we drink the most of ourselves on a slow morning.
What this means for how you actually buy matcha
If a tin lists a cultivar, that's not just trivia for the label, it's telling you what to expect before you open it. Yabukita for a bolder, more assertive cup that plays well with milk. Okumidori for something rounder if you're drinking it plain but want a little more body. Saemidori if you want the sweetest, gentlest version and don't mind paying more for a smaller harvest.
Next time you're deciding between grades, skip the marketing copy on the box and look for the cultivar name instead. It'll tell you more about what's actually in your bowl than any grade label will.
