Blending to an approved sample

A buyer with a cup to protect does not need a grade code; they need a match and a way to hold it. We cup the reference under fixed conditions, build a blend from lots that reproduce it, and once approved, that sample becomes the contract reference. Where repeat-lot matching is contracted, later lots are cupped against the retained reference before release. This is how a retail brand keeps the same cup across a season in which the leaf itself changes.

Service

Which categories can be matched?

Green tea blends built from gunpowder and Chunmee grades; jasmine at a stated scenting round; and origin categories where the reference is itself Fujian tea. A Wuyishan rock oolong cannot be matched from Anxi leaf, and we say so rather than approximating.

02

What goes into a custom tea blend brief?

A custom blend is specified in writing, not by name. The brief lists the base teas and any other ingredients with their share, the target cup described against a sealed reference sample, what may be substituted when a component is out of season, and who owns the recipe. A recipe on paper alone rarely reproduces a cup: leaf size, season and storage change the result, which is why the approved sample, not the recipe, becomes the reference.

よく聞かれる質問

Can you match my current supplier's tea?

Usually, if it is a green tea blend, a jasmine tea or a Fujian category. Send a sealed sample; we cup it, propose a match, and only after your approval does it become the reference.

What is cupping?

Standardised sensory evaluation of a lot against an approved sample — fixed leaf weight, water volume, brewing time and vessel, as set out in ISO 3103 — so that two cuppings are comparable.

カスタム茶ブレンドのために買い手が送るものは?

可能なら密封した基準サンプルに加え、目標とする味、原材料制限、仕向地、包装、予定数量を送ります。必須の特徴と、入手性やコストに応じて調整できる特徴を明確にしてください。写真やフレーバー名だけでは、茶葉外観、香り、液色、後味を確実に再現できません。

茶ブレンドを遠隔で承認する方法は?

まず抽出方法を合意し、同じ水、使用量、温度、時間でコード付きサンプルを評価します。香り、抽出液、味、後味、茶葉外観を記録し、承認コードを書面で確認してください。契約で定める場合は密封基準を保管し、後続ロットを同じ方法で比較します。

What is a white-label tea blend?

A blend the supplier already makes and sells to several brands, each under its own label. A custom or original blend is built for one buyer, who can own the recipe and the reference sample. Agree which it is, and whether the blend is exclusive, in the contract.
