Matcha Cultivars and Harvest Grades Explained | What It Means for Bulk Matcha Orders
By Chuong Akiyama | May 2026
Most wholesale buyers know the difference between ceremonial and culinary-grade matcha. Fewer understand what sits beneath those labels: the cultivar of the tea plant itself and the harvest window from which the leaves were picked. These two factors, cultivar and harvest timing, are the foundational decisions that determine everything about the matcha in your cup, from its amino acid profile and sweetness to its color intensity and price point. For businesses ordering wholesale matcha powder, knowing how to read and evaluate these factors separates informed purchasing from guesswork.
This article breaks down the primary tea cultivars used in Japanese matcha powder bulk production, explains how first harvest and second harvest timing affects quality, and shows matcha supplier customers how to use this knowledge to make smarter bulk purchasing decisions. If you source the best Japanese ceremonial grade matcha or any grade of matcha powder bulk from Japan, this is essential reading.
What Is a Tea Cultivar and Why Does It Matter?
A cultivar is a cultivated variety of the Camellia sinensis plant that has been selectively bred for specific characteristics. Think of it like grape varieties in wine. Just as a Pinot Noir grape produces a fundamentally different wine than a Cabernet Sauvignon, different tea cultivars produce matcha with distinctly different flavor profiles, amino acid concentrations, and visual characteristics.
Japan has registered over 100 tea cultivars, but only a handful are commonly used for premium matcha production. Each cultivar has been developed over decades or centuries through careful selection and crossbreeding to optimize specific traits, such as sweetness, umami depth, chlorophyll production, cold resistance, or disease tolerance. The cultivar a farmer chooses to grow determines the genetic potential of the matcha before any processing begins.
For wholesale matcha buyers, cultivar information is a quality signal. A supplier who can tell you which cultivar their matcha comes from demonstrates transparency and product knowledge. A supplier who cannot, or who sells generic "Japanese matcha" without cultivar details, may not have the depth of relationship with their tea farms that premium quality requires. When evaluating a new matcha supplier, asking about the cultivar is one of the most revealing questions you can pose.
The Major Matcha Cultivars You Should Know
Yabukita
Yabukita is the most widely planted tea cultivar in Japan, accounting for roughly 75 percent of all tea production. It was developed in Shizuoka Prefecture in the early 20th century and became dominant because of its reliability: strong yields, good disease resistance, and adaptability to different growing conditions. Yabukita produces matcha with a balanced, approachable flavor, moderate umami, mild sweetness, and a clean finish. It is the baseline against which other cultivars are often compared.
For wholesale buyers, Yabukita matcha represents solid, dependable quality. It is the cultivar you are most likely to encounter in commercial-grade matcha, and a well-produced Yabukita matcha from a reputable source delivers excellent value for everyday café use, particularly in barista and culinary-grade applications.
Saemidori
Saemidori is a premium cultivar prized for its exceptionally vivid green color and high amino acid content. The name translates roughly to "clear green," which describes the brilliant, almost luminous green of its leaves and the matcha produced from them. Saemidori has notably higher L-theanine levels than Yabukita, which translates to a sweeter, more umami-rich flavor with virtually no bitterness.
For businesses seeking the finest ceremonial matcha, Saemidori is often the cultivar of choice. It produces matcha that impresses even experienced tea drinkers, and its striking color makes it ideal for drinks where visual presentation matters. AKI MATCHA sources Saemidori from our partner farms in Shizuoka, where the volcanic soil and climate create ideal growing conditions for this demanding cultivar.
Okumidori
Okumidori is another highly regarded matcha cultivar, known for its deep, rich umami character and a slightly darker green color than Saemidori. The flavor profile tends toward savory complexity rather than sweetness, making it a favorite among tea connoisseurs who appreciate depth and nuance. Okumidori matures slightly later than Yabukita, which means it is sometimes harvested a few days into the harvest window rather than at the very start.
For wholesale applications, Okumidori produces exceptional ceremonial grade Matcha Okumidori and premium barista grade matcha. Its rich character holds up well in milk-based drinks without losing its distinctive personality, which makes it versatile across menu applications.
Gokou
Gokou is a cultivar particularly popular in Uji, Kyoto, one of Japan’s most historic matcha-producing regions. It is known for its intense umami, full body, and slightly creamy texture that distinguishes it from other cultivars. Gokou can be more challenging to grow than Yabukita, which limits its availability and contributes to higher pricing for matcha produced from this cultivar.
Gokou matcha is often found in competition-grade and ultra-premium ceremonial products. For wholesale buyers serving a discerning clientele that values exceptional quality, Gokou-origin matcha positions your offering at the top tier of the market.
Asahi
Asahi is one of the oldest cultivars used specifically for matcha production. It is relatively rare because it requires more careful management and produces lower yields than modern cultivars. However, Asahi matcha has a distinctive smoothness and elegance that many tea masters consider unmatched. It is primarily found in very limited, premium-priced ceremonial matcha.
Cultivar Comparison at a Glance
First Harvest vs. Second Harvest: The Quality Divide
Beyond cultivar selection, harvest timing is the second most important factor determining matcha quality. Japanese tea is harvested in multiple rounds throughout the growing season, and each harvest produces leaves with distinctly different characteristics.
First Harvest (Ichibancha) — Spring
The first harvest occurs in late April to mid-May, when the tea bushes produce their first flush of new growth after winter dormancy. These young, tender leaves have spent the winter accumulating nutrients in the roots, which are released into the new growth as temperatures rise in spring. First-harvest leaves contain the highest concentrations of L-theanine, the amino acid responsible for matcha’s smooth sweetness, calm-alertness effect, and umami depth.
Because these leaves are also shade-grown for 20 to 30 days before picking, the L-theanine levels are further amplified while bitterness-causing catechin conversion is slowed. The result is matcha with the richest flavor, most vivid color, and highest nutritional density of the entire year. All premium ceremonial-grade matcha comes exclusively from this harvest. For a detailed look at how these compounds work, see our article on EGCG and antioxidants in matcha.
First-harvest matcha commands the highest prices because the supply window is narrow, the yield per plant is limited to the first flush of spring growth, and the quality is unmatched by any subsequent harvest. For wholesale buyers, specifying first-harvest origin is the single most impactful quality decision you can make when placing bulk orders.
Second Harvest (Nibancha) — Summer
The second harvest occurs approximately six to eight weeks after the first, typically in June or July. By this point, the tea bushes have produced a second round of growth under full summer sunlight and higher temperatures. Second-harvest leaves are more mature, have lower L-theanine content, and contain higher levels of catechins, which contribute a more astringent, slightly bitter flavor.
Second-harvest matcha has less sweetness, less umami, and a less vibrant green color compared to first-harvest. However, it is still genuine matcha when properly processed, and it serves well in applications where the matcha flavor is blended with other ingredients. Most standard barista-grade and all culinary-grade matcha comes from second-harvest or a blend of harvests.
Third Harvest and Beyond
Some farms produce a third harvest (sanbancha) in autumn. These leaves have the lowest nutritional density and the most robust, bitter flavor. Third-harvest tea is rarely used for quality matcha production and is more commonly processed into lower-grade green tea products or blended with earlier harvests to create budget matcha. Reputable matcha producers typically do not use third-harvest leaves for any product labeled as matcha.
How Harvest Timing Connects to Matcha Grades
The grading system used in the matcha industry, ceremonial, barista, and culinary, is directly tied to harvest timing and cultivar selection. Understanding this connection helps wholesale matcha buyers evaluate whether the grade on the label matches the actual quality inside the bag. For a broader comparison of these grades, our article on ceremonial grade vs culinary grade matcha provides additional context.
A key point for wholesale buyers: the terms ceremonial, barista, and culinary are not regulated by any certification body. They are industry conventions applied by each producer based on their own standards. This means a bag labeled "ceremonial grade" from one supplier might be produced from first harvest Matcha Saemidori leaves , while another supplier’s "ceremonial grade" could be second-harvest Yabukita. The label alone does not tell you the full story. You need to ask about the cultivar and harvest to verify that the quality matches the grade claim.
Practical Implications for Wholesale Ordering
Matching Cultivar to Application
If your business serves straight matcha or premium matcha drinks where flavor takes center stage, investing in Saemidori or Okumidori cultivar matcha from the first harvest delivers a noticeably superior product. AKI MATCHA’s ceremonial grade uses the Saemidori cultivar from our Shizuoka farms, selected specifically for its sweetness and vivid color.
For high-volume latte programs where milk moderates the matcha flavor, Yabukita-based barista-grade matcha provides excellent quality at a more accessible price point. The balanced profile of Yabukita works beautifully with dairy and plant-based milks without requiring the premium pricing of rarer cultivars.
Understanding Price Differences
Cultivar rarity directly affects pricing. Yabukita is widely available, so Yabukita-based matcha is generally the most affordable. Saemidori, Okumidori, and Gokou are produced in smaller quantities, which means matcha from these cultivars costs more. First-harvest matcha from any cultivar costs more than second-harvest matcha from the same cultivar. When your supplier quotes pricing, the cultivar and harvest combination explain most of the price variation you see across different products. Understanding why matcha is more expensive than other teas becomes much clearer when you see it through the lens of cultivar and harvest economics.
Seasonal Availability
First-harvest matcha is available once per year, and the supply for each cultivar is fixed by the yield of that single spring picking. Wholesale buyers who want to secure specific cultivar and harvest combinations should place orders or reservations well in advance of the harvest season. The global matcha supply shortage affecting the matcha market make early ordering even more important for premium cultivars, which sell out fastest.
Questions to Ask Your Matcha Supplier About Cultivar and Harvest
When evaluating a matcha supplier or placing a new bulk order, these questions will help you verify quality and make informed decisions:
What cultivar is this matcha made from? A transparent supplier will answer immediately. If they cannot, or respond with something vague like "a blend of Japanese cultivars," that is a signal to investigate further.
Is this from the first harvest or the second harvest? This single question reveals more about quality than almost any other. First-harvest matcha costs more but delivers measurably better flavor, color, and nutritional content.
Which prefecture and farm does this come from? Origin specificity demonstrates supply chain integrity. "Shizuoka Prefecture" is a good answer. "Japan," without further detail, is too vague for premium matcha sourcing.
Can I taste before I commit to a bulk order? Reputable suppliers always allow sampling. AKI MATCHA provides sample packs so you can evaluate cultivar, harvest quality, and grade performance in your actual recipes before placing a larger commitment.
