How to Evaluate Matcha Samples Before Your First Order

By the Origin Leaf Japan team | Reviewed by Yasuhiro Odajima, Chief Matcha Officer | Last updated: October 2026

Short answer: Evaluate matcha samples in three stages: first, a controlled tasting with water only; second, a test in your real recipe with your milk and sweetener; and third, a documentation review covering specifications, compliance, and supply terms. Use the same dose, water, and temperature for every sample, score each one on a simple sheet, and keep a retained portion to compare with future deliveries.

Key takeaways

• Standardize preparation so differences come from the matcha, not the method.
• Always taste with water before testing in drinks.
• Test in your best-selling recipe with your actual milk.
• Score color, aroma, umami, sweetness, bitterness, texture, and color stability.
• Confirm that the sample represents the lot you will receive.

Stage 1: Set up a fair comparison

• Dose: 2 g of matcha per sample.
• Water: 60 to 70 ml of soft, filtered water at 70 to 80 °C (160 to 175 °F).
• Tools: Identical bowls or cups, a bamboo whisk or the same frother, a scale, and a sieve.
• Blind tasting: Label samples with codes so tasters do not know the supplier or price.
• Palate: Taste in the morning if possible, with water between samples.

Stage 2: Water-only tasting and scoring

Sift each sample, whisk, and evaluate immediately. Score each attribute from 1 to 5.

Stage 3: Test in your recipe

Prepare your top-selling matcha drink with each sample, using your standard milk, sweetener, and dose. Assess whether matcha flavor comes through the milk, whether the drink's color looks appealing, and whether the cost per cup works. If you use several milks, test the most popular two.

Stage 4: Review the documentation

• Harvest, cultivar, and origin of the lot
• Milling date or milling-to-order policy
• Best-before and storage recommendations
• FDA registration (US) and FSVP support, or residue testing (EU and UK)
• Farm and factory certifications and their dates
• MOQ, pack size, price, lead time, and how future pricing is set

Stage 5: Confirm consistency

Ask the supplier to confirm that your first order will come from the same lot or meet the same specification. Retain about 20 g of the approved sample in a sealed bag in the refrigerator to compare against deliveries.

Common mistakes to avoid

• Comparing samples prepared with different water temperatures or doses.
• Tasting only in lattes.
• Judging on price alone.
• Approving a sample without confirming it matches the commercial lot.
