Keeping Flavour Consistent Across Locations

More sites means more variance. Matcha adds its own complications.

The raw material is agricultural

Matcha is ground from a crop. Harvest year, field, and cultivar all move the flavour.

The same product name can taste different between lots. That is a property of the material, not a defect.

Foodservice products are blended from multiple sources specifically to absorb this.

"To taste" does not survive across locations.

Fix these and standardise the measuring tools. Removing room for judgement narrows the spread.

Liquid added to powder all at once clumps. Dissolving in a small amount of hot water first is not optional.

Skipping it under pressure produces different results by site. Put it in the procedure with the reason attached.

Powder is sensitive to light, heat, and moisture, and absorbs odours.

Where it sits in the kitchen, how it is handled after opening — differences here produce flavour differences from identical product.

Record opening dates and enforce first-in-first-out.

Volume varies by location.

Post-opening guideline is two weeks to a month. A low-volume site holding a large package serves declining quality in the back half.

Order sizes should match each site's throughput.

Matcha does not scale quickly. Japan's 2025 green tea exports roughly doubled in value and conditions are tight.

Confirm that volume matching your site count can be secured continuously.

Switching suppliers changes the flavour. Staggered rollouts mean one chain serving two different drinks.
