If you're just getting into the matcha game or have been in it for a while, you might still ask yourself: What differentiates good matcha from bad matcha?

The Foundation: Harvest Timing and Growing Conditions

The journey to exceptional matcha begins in the tea gardens of Japan. Premium matcha must be a spring harvest tea – specifically the first picking of the year, known as ichibancha. A second summer harvest lacks the sweetness and umami that makes first-flush matcha so prized.

Equally important is the shade-growing process. Quality matcha requires that tea plants be covered for the final 3-4 weeks before harvest. This crucial step forces the plants to produce more chlorophyll and amino acids, resulting in a sweeter cup with more complexity and that signature umami flavor that distinguishes ceremonial-grade matcha.

Visual Indicators: Reading the Color

One of the most reliable indicators of matcha quality is its color. Premium matcha should display a deep, vibrant forest green – almost electric in its vibrancy and full of life. This rich color indicates proper shade-growing and careful processing.

There are exceptions where darker matcha can taste good when produced using unorthodox methods, but as a general rule, avoid matcha that appears yellowish, brownish, or dull olive green. These colors typically indicate older tea, poor storage, or inferior processing.

The Aroma Test: Your First Quality Check

Anytime I taste new matchas from producers, I always start by opening the bag and smelling the tea. Quality matcha should smell fresh, sweet, and floral – almost like freshly cut grass mixed with a subtle sweetness. While a good aroma doesn't guarantee excellent taste, it's a positive indicator that the matcha has been well-processed and properly stored.

If the matcha smells stale, musty, or has no aroma at all, it's likely past its prime or of inferior quality. Fresh matcha should have a distinct, pleasant fragrance that makes you want to taste it.

The Ultimate Test: Taste Evaluation

Pro Tasting Method

I always taste matcha as koicha (thick tea): 2.5-3 grams of matcha, 70°C water, whisked to a thick consistency, then drunk as a shot. This concentrated preparation reveals any deficiencies immediately – there's nowhere for flaws to hide.

Signs of Bad Matcha:

  1. Fishy taste – Often indicates poor storage or contamination
  2. Overwhelmingly grassy and bitter – Sign of late harvest or poor processing
  3. Chemical-like bitterness – Almost poisonous taste indicating very low quality

Characteristics of Excellent Matcha:

  1. Rich and full-bodied – Complex flavor that fills your palate
  2. Creamy texture – Smooth, almost buttery consistency
  3. Natural sweetness – No added sugar needed
  4. Balanced umami – That savory-sweet finish unique to premium matcha

The Wisdom of Experience

At the end of the day, you should buy what smells good and tastes good to you. During my time working for Harney & Sons Fine Teas, one of New York's most reputable tea companies, I learned an invaluable lesson from the founder, John Harney.

"If you take a sip of tea and immediately smile right afterwards, then it's the tea for you."

— John Harney, Founder of Harney & Sons Fine Teas

This simple wisdom cuts through all the technical details. While understanding quality markers is important, the ultimate test is your own enjoyment. Good matcha should bring joy, not just meet a checklist of characteristics.

Conclusion: Trust Your Senses

Identifying quality matcha becomes easier with experience, but these guidelines will help you avoid disappointment and find truly exceptional tea. Remember: spring harvest, shade-grown, vibrant green color, fresh aroma, and a sweet, umami-rich taste are your key indicators.

Whether you're preparing matcha for a traditional tea ceremony or your morning latte, starting with quality tea makes all the difference. Take time to evaluate your matcha using these criteria, and you'll soon develop the confidence to distinguish the exceptional from the ordinary.
