Six Things to Check"},"content":{"rendered":"\n

Bitter Longjing tea is often a brewing problem you can adjust; weak tea may simply need a little more extraction.<\/strong> Before blaming the leaves, record the dose, water volume, temperature and time. Changing everything at once makes it difficult to learn what helped.<\/p>\n

Start with the six checks below. They cover both sides of the problem: a cup that feels harsh and drying, and one that tastes like little more than hot water.<\/p>\n

\"Teapot

First, separate bitterness from astringency<\/h2>\n

Bitterness is a taste; astringency is the drying, tightening sensation you may notice in the mouth. They can occur together, but they are not the same. A little bitterness can be part of a balanced green tea; an unpleasant cup is a reason to adjust the brew, not an automatic verdict on origin or price.<\/p>\n

Caffeine and several polyphenols contribute to bitterness, while tea polyphenols also contribute to astringency. Their amounts vary with the leaves and processing. A fixed chemical percentage cannot diagnose your particular cup.<\/p>\n

\"Tea

1. Check the leaves and the batch<\/h2>\n

Look for a clean dry aroma, the stated harvest year and a plausible storage history. Broken pieces expose more surface area and may extract differently from intact flat leaves. Judge the batch you have, rather than expecting the product name to guarantee a result.<\/p>\n

\"A

Season and cultivar can affect character, but \u2018spring\u2019 does not guarantee sweetness, and a more forceful cup is not proof of a summer harvest. Origin cannot be confirmed by bitterness either.<\/p>\n

\"Tea

If the tea smells musty or shows visible mold, do not try to rescue it with hotter water or a rinse. If drinking causes unusual discomfort, stop using that tea rather than treating numbness as a normal quality test.<\/p>\n

2. Check the leaf-to-water ratio<\/h2>\n

Too much leaf in a small cup can produce a concentrated, bitter brew even with a short steep. Too little leaf in a large mug can taste thin. Count actual milliliters, not an undefined \u2018cup\u2019, and weigh the leaves at least while learning.<\/p>\n

\"Water

A useful reset is 3 g for 200 mL<\/strong>. If your current cup is harsh, use a fresh dose and reduce it slightly, keeping the other settings unchanged. If it is weak, first extend the time a little; if still thin, try 3.5 g on the next fresh brew.<\/p>\n

Do not compare that drained-cup ratio directly with a small gaiwan recipe using much more leaf and very short infusions. Dose and time work together.<\/p>\n

3. Check the water temperature<\/h2>\n

Temperature affects how quickly flavor compounds move into the water. A very hot, long infusion of tender leaves can become difficult to enjoy. Water that is too cool for a brief steep may leave the cup underdeveloped.<\/p>\n

\"Hot

Try 80\u00b0C (176\u00b0F) as a starting point. For a harsh cup, shorten the time first or compare a fresh brew at 75\u00b0C (167\u00b0F). For a thin cup with the right dose, try a small increase toward 85\u00b0C (185\u00b0F). Keep a note so you can repeat the version you like.<\/p>\n

4. Check how long the leaves stay in contact with water<\/h2>\n

The timer does not stop when you take the first sip. Leaves left in a glass continue to extract. A cup that is pleasant at one minute can become strong while you answer a message or leave it on the desk.<\/p>\n

\"Tea

For a controlled comparison, taste at one minute and separate the liquid from the leaves. If weak, extend by 15\u201330 seconds. If harsh, shorten the next fresh brew. When using a glass with leaves left inside, reduce the dose to suit your drinking pace instead of trying to apply a drained-cup timer unchanged.<\/p>\n

5. Compare the water<\/h2>\n

Use drinking water without a strong odor. Residual chlorine can affect aroma; mineral content and pH can also change the appearance and flavor. Try the same recipe once with suitable filtered water if the usual cup seems dull.<\/p>\n

A shiny surface film is a different issue from a chlorine smell. Research on tea-film formation<\/a> describes interactions between tea polyphenols and ions in water, with hardness affecting the film. It does not support the simple claim that chloride \u2018rusts\u2019 tea into an oily layer.<\/p>\n

\"Tea

A photograph of surface film cannot establish safety, contamination or tea quality. Check that the vessel is clean and compare water sources; do not use the film as a test for authentic West Lake Longjing.<\/p>\n

6. Check storage and expectations<\/h2>\n

Heat, air, moisture, light and nearby smells can reduce the appeal of stored green tea. A flat aroma cannot always be restored by adding more leaves. Buy a manageable quantity and keep it sealed according to the producer\u2019s guidance.<\/p>\n

\"Terraced

A garden photograph tells you about a landscape, not how your opened bag has been kept. Ask about storage when buying late in the year, and do not confuse a website\u2019s \u2018new\u2019 badge with a new harvest.<\/p>\n

A quick troubleshooting table<\/h2>\n

Bitter and very strong<\/td>\nLong contact or high dose<\/td>\nShorter steep; then consider less leaf<\/td>\n<\/tr>\n

Good first sip, harsh later<\/td>\nLeaves left in the cup<\/td>\nDrain, remove the strainer or reduce dose<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

For a clean reset, use fresh leaves, 3 g per 200 mL, 80\u00b0C water and a one-minute first taste. That gives you a repeatable reference. The goal is a cup you enjoy, not forcing every Longjing to taste identical.<\/p>\n
