Twelve Matchas
in Milk.
The eleven specimens from No. 01 plus one new addition (M504), retasted as lattes — every cup served first unsweetened, then with house simple syrup. A calibrated two-rater screening protocol across eight sensory dimensions, including color payoff and matcha presence, scoring with the notation [unsweet] : [sweet] :: [overall]. The thesis under examination: the same matcha is not the same drink.
All twelve, ranked by combined latte overall.
Each cell links to its full specimen profile below. Combined overall is the mean of both tasters' overall scores. M167 served as the calibration anchor for the latte round (tasted twice by each rater within a 40-minute window). Rankings here are for the latte context only; see Specimen Report No. 01 for the same cohort's usucha rankings — the orderings differ meaningfully.
Each specimen plotted by its combined unsweetened overall (x) against its combined sweetened overall (y) — the rater-synthesized scores derived as Combined Overall ± Sweet Uplift / 2, the same numbers used in the leaderboard. Distance above the diagonal is the magnitude of sweetener's benefit; on the diagonal, sweetener is neutral; below it, sweetener hurts.

Three editorial reads emerge: M217 earns its top rank in both axes — a balanced cup that doesn't depend on sugar. M167 and M504 show the largest sweetener uplifts (≈ +0.8) — both essentially require sweetening to express. The low-uplift cluster of M742 · M632 · M287 · M853 · M177 hugs the diagonal; recommendation depends on whether your house spec favors sweetened or unsweetened service. M552 and M631 sit deep in the marginal zone in both states — no format saves them.
Tier thresholds match those of No. 01 to allow direct cross-format comparison. Sweet uplift is the change in combined overall score from unsweetened to sweetened; values range from +0.81 (M167) and +0.80 (M504) at the top to +0.10 at the bottom (M632, M287, M631). M552 — marginal in usucha — shows surprisingly strong response (+0.46).
† Reference point — estimated typical score for mass-market grocery-store matcha served as a sweetened latte under this protocol. Not a measured rating; included as a category anchor for readers unfamiliar with specialty matcha. The bump from No. 01's ~3.5 reflects milk and sweetener softening structural defects.
In descending order of latte merit.
Each profile shows both raters' sensory polygons overlaid on the six axes shared with No. 01: Taster A in matcha green, Taster B in gold. The two latte-specific axes (color payoff, matcha presence) and the sweet uplift appear as badges in each header. Scores reflect averages where multiple sessions exist.
Solid floral and deep umami, present through milk; smooth, silky mouthfeel. Sweetness smoothens the aroma slightly; would benefit from a lower sweetness spec.
Notable deep savory echo of matcha flavor with light top notes. Marked deep green flavor, umami, and coating mouthfeel. Highly recommend 217 to be considered as one of the lattes to represent Iro Tea.
Verdict Top latte candidate. Holds identity through milk; minimal syrup needed.
Disappears in milk unsweetened — possibly insufficient low-end weight. Sugar brings up matcha presence substantially; lifts the top-end sufficiently for expression through milk.
Not particularly noticeable matcha latte. Lacks character without syrup. With syrup, a hint of sweet umami balance emerges; this matcha pronounces the syrup's sweetness more than others.
Verdict Sweetened-only; matcha disappears unsweetened. Strong signature-drink candidate where sweetness is part of the spec.
Bright, slightly thin green aroma. Clean, subtle profile; better suited for usucha than milk. Sweetener moderately increases presence and brightness.
Subtle bloom of umami with clean finish. Soft and light; barely holds identity through milk. A little syrup goes a long way. Top-tier latte candidate when sweetened.
Verdict Light-bodied; needs careful sweetener handling to express through milk.
Bright yet warm green, grassy and creamy aroma. Notably smooth mouthfeel. Faint bitterness, but remains hidden in the milk. Sweeter aroma and mid-palate with moderate umami.
Almost too flat to be recognizable in latte structure unsweetened. Syrup lit the dark room — top and mid body became noticeable. Clean and balanced umami, well integrated when sweetened.
Verdict Sweetened-only profile with a notably clean mouthfeel; the cohort's only newcomer (not in No. 01).
Moderately bright grassy aroma. Balanced umami profile, but seems to disappear in milk. Slightly grainy texture with sweetener.
Light and delicate aroma with balanced mid-palate, silky mouthfeel. Among the most delightful and bright profiles. Less syrup is better — easily swayed; delicacy gets rounded out.
Verdict Best served unsweetened; syrup masks the floral subtlety. A delicate latte option for refined palates.
Balanced, green matcha. Not particularly cutting through milk, but fairly present. Sweetness contributes to a smoother mouthfeel and boosts perception of attack.
Without syrup, milk-with-matcha-flavor description fits. Notably clean finish. With syrup, matcha aroma cuts through the milk and opens the top notes.
Verdict Reliable middle-of-the-pack latte; benefits modestly from sweetener. Served as the round's calibration anchor (tasted twice).
Moderate darker green, grassy. Leaves more brightness to be desired. Fairly present in milk but leans lighter. Sugar provides slight rounding, no substantial change.
Full-bodied; subtle deep umami with minimal chalkiness. Matcha-latte rather than matcha-flavored milk. Syrup pronounces top, light and bright notes — beautifully immersed.
Verdict Strong sweetened-latte candidate; the cohort's third-largest combined uplift (+0.62) — sugar carries it.
Mid-heavy dull green; slight creamy oat aroma. Slight graininess. Sweetness recovers the dullness; brings out deeper and higher notes.
Full-bodied matcha with balanced top and mid notes; fresh and healthy flavor profile. Doesn't necessarily cut through milk, but the greenness is very present. Strong mid-body.
Verdict Sweetened-latte candidate per Taster B; Taster A reads it as dull. 1.43-pt rater gap warrants re-tasting.
Moderately dark vegetal green. Slight bitterness; slight dry finish. Hollow, absent body and brightness even after sugar. Bitterness resolves with sweetener.
Darker green notes with strong mid-body structure. Hard to identify top notes but pleasant overall build. Syrup defines top notes and evens out lighter flavors. Complex and well-structured.
Verdict Sweetened-latte candidate with caveats. 1.4-pt rater divergence — second-flush character may explain the split. Re-tasting warranted.
Bright, grassy with subtle oat notes. Solid balance, subtle top-end roll-off. Sweetness notably increases creaminess and attack; rounds the overall profile.
Fairly present matcha through mouthfeel rather than flavor. Slightly grippy; dull matcha body. Syrup brightens but lacks depth, brightness, and character.
Verdict Sweetened-only at best; the cohort's tightest rater-agreement score, reached via opposite reasoning.
Dark, dull profile; cuts through milk in an aggressive, unbalanced way. No top-end definition. Sugar fills missing brightness — significant impact on perceived aroma and umami.
Darker and stronger matcha presence than 167. Hint of astringent grip + chalkiness, grassy hit to mouthfeel. Syrup masks the chalkiness; contribution to flavor profile negligible.
Verdict Format redemption from usucha — cuts through milk. Better as latte than usucha, but still marginal.
General green, grassy aroma; flat character, not much umami or brightness. Slight grainy mouthfeel. Sweetness benefits attack only — not much character to enhance.
Lighter flavor and color profile, almost dry in texture and brightness. Slight astringency at the tail. Syrup highlights floral scent but lacks the mid-body and boldness expected in matcha.
Verdict Bottom of the cohort across both formats. No latte path forward.
