Step 1
Pick the grade by the cup, not by the label.
"Ceremonial" and "culinary" are marketing words, not regulated grades. What matters for a launch is the cup result your customer will actually taste and see.
Colour and mouthfeel
For lattes and retail tins, buyers usually want a bright, clean green and a smooth, umami-forward taste without harsh bitterness. Request the particle size and shade-grown or tencha-base information that supports that result.
Application fit
A matcha that shines as a straight usucha may not be the most cost-effective choice for a milk-heavy latte. Tell the supplier the serving format - whisked, iced latte, bakery dusting - so the sample is selected around it.
