A small comparison protocol for recording your own observations, changing one brewing variable and deciding what to try next.
Ask one answerable question
A useful home tasting begins with a narrow question, such as 'Do I prefer this tea with a 20-second or 30-second first infusion?' It does not need an elaborate vocabulary or a score that pretends to measure universal quality. You are recording your preference under stated conditions. This guide proposes a simple comparison method; it does not report a KongMing tasting trial or promise that another drinker will perceive the same result.
Start from the relevant product's brewing directions if you need a baseline. Supplier settings are starting points for that product, not evidence that one temperature or ratio is best for every tea.
Write the baseline before you brew
Label the leaf with its product name, batch or harvest information if available, and the date you opened the pack. Record dry leaf mass, measured water volume, water source, vessel, water temperature and steep duration. Include a short note on how you time the pour. Starting a timer at the first drop and starting it after filling are different procedures, especially for a short infusion.
Use the same cups and similar tasting temperatures. A cup tasted immediately and another left standing for several minutes are a poor direct comparison. Let both become comfortable to drink, and record any practical mismatch instead of treating the session as more controlled than it was.
Change a single variable
For a time comparison, prepare two fresh, equal leaf portions from the same pack. Keep the dose, water and vessel as similar as possible. Label one preparation A and the other B. For example, A uses 20 seconds and B uses 30 seconds, with the same timing convention. The difference is 10 seconds; the relative increase is (30 − 20) ÷ 20 × 100 = 50%.
If you have only one vessel, clean it and repeat the same preparation sequence for the second portion. Note that this sequential approach introduces cooling and timing differences. Comparing the first infusion of one portion with the second infusion of the same leaf changes both infusion number and time, so it does not isolate duration.
Record observations separately from preference
Use a small card: preparation label; aroma words; perceived sweetness; bitterness; drying mouthfeel; body; finish; overall preference; next change. For any numbered scale, define its endpoints. For instance, bitterness from 0, not noticed, to 5, very pronounced to you. These numbers describe your observations in this session; they are not laboratory measurements or a health assessment.
Be specific when useful: 'A feels lighter; B has more bitterness; I prefer A today' preserves more information than 'A is superior.' Leave an entry blank when you cannot identify a difference. Inventing a tasting note to complete every box makes the record less useful.
Use the result to choose the next comparison
Repeat on another day before making a strong claim. Reversing the tasting order can reveal whether the first cup consistently receives your preference. If results disagree, keep both records. Changes in water, pouring, food or attention may help explain the inconsistency. Select one next adjustment, such as testing 25 seconds between the original options. Your notebook becomes valuable through traceable decisions, including inconclusive ones, rather than through confident descriptions of every cup.
