First Flush, Second Flush, and What's Actually on Your Tea Label

Most tea labels are written for people who already know what they're looking at. If you're new to loose leaf tea — or you've been drinking it for a while but never fully cracked the vocabulary — the back of a tea tin can feel like it's in a different language. "FTGFOP1," "first flush," "broken leaf," "orthodox manufacture" — these are real terms with real meanings, but they're almost never explained on the packaging itself.

This is the post where we explain what the common ones mean and which ones actually matter for taste. We're going to focus on the terms that show up on our packaging and on the packaging of most loose-leaf teas you'd buy from a specialty tea shop. If a term doesn't show up in this guide, it's either regional dialect or marketing copy and you can mostly ignore it.

If you're earlier in the loose-leaf journey and just want to know how to brew tea well at all, our matcha brewing guide and our water temperature chart are the more foundational reads. This post assumes you've already figured out how to brew a decent cup and you're now curious about the vocabulary on the bag.

Flush: the seasonal harvest window

"Flush" is the most useful single word on a tea label and the one most often misunderstood. It refers to the seasonal growth cycle of the tea plant. The tea plant (Camellia sinensis, the same species whether the final product is black, green, white, or oolong) produces new leaves in regular growth flushes throughout the growing season. Each flush has slightly different flavor characteristics because the leaves were picked at different points in the plant's growth cycle, under different weather conditions.

In most tea-growing regions, the calendar runs roughly like this:

• First flush (also called "spring flush" or "spring pick"): the first growth of leaves after the winter dormancy. The leaves are tender, smaller, more delicate. The cup tends to be lighter, brighter, more floral, more vegetal. This is the most prized flush for high-grown teas like Darjeeling and certain Chinese green teas. Picking happens between late February and early May, depending on region and elevation.
• Second flush (also called "summer flush"): the second growth cycle, after the first flush leaves have been harvested and the plant has regrown. The leaves are larger, more mature. The cup tends to be fuller-bodied, more amber in color, more muscatel or malt-forward in flavor. For Darjeeling specifically, second flush is when the famous "muscatel" character shows up — a flavor that doesn't appear in any other tea. Picking happens between late May and early July.
• Autumn flush (also called "third flush" or "rains flush"): the third growth, after the summer monsoon. The leaves are the most mature of the year. The cup tends to be deeper, more woodsy, sometimes more astringent. This flush is less commonly exported and less commonly celebrated, but it has its fans. Picking happens between late September and November, depending on region.
• In-between flushes (called "in-between," "rain flush," or "unspecified"): tea picked outside the three main flushes, usually during monsoon season or shoulder periods. The cup is variable — sometimes thin, sometimes dull. Most specialty tea buyers pass on these.

For most drinkers, flush matters a lot when the tea is Darjeeling, and somewhat when it's a Chinese green tea or Japanese sencha. For other categories — Chinese black, most oolongs, white teas — flush is either not used or used differently (white teas are sometimes classified by "picking standard" instead, like "bud and first leaf" or "bud and second leaf," which is a related concept).

The practical version: if you're buying Darjeeling and you want the bright, floral, almost-grassy cup, look for first flush. If you want the deeper, fuller-bodied, muscatel cup, look for second flush. If the label just says "Darjeeling" without a flush, it's probably second flush (because that's what's most exported) or an in-between flush (the cheapest option), and you'll have to ask.

Leaf grade: FTGFOP and its friends

This is the part of tea labels that looks most intimidating and matters least to most drinkers. FTGFOP stands for "Finest Tippy Golden Flowery Orange Pekoe," and it's part of a system the Indian and Sri Lankan tea industries use to grade black tea by leaf size and appearance.

The full hierarchy, from highest to lowest visible grade, runs roughly like this:

• SFTGFOP (Super Fine Tippy Golden Flowery Orange Pekoe) — the highest grade, includes the most tip (the pale, unopened leaf bud at the tip of the tea plant's newest growth). Almost exclusively used for the top-grade first flush Darjeelings.
• FTGFOP (Fine Tippy Golden Flowery Orange Pekoe) — high grade, lots of tip still present. Top first and second flush.
• TGFOP (Tippy Golden Flowery Orange Pekoe) — high grade, less tip than FTGFOP.
• GFOP (Golden Flowery Orange Pekoe) — mid-grade, includes "golden" tips but fewer of them.
• FOP (Flowery Orange Pekoe) — the base grade, named for the historical Dutch East India Company "orange pekoe" classification. The "orange" here is not the fruit — it's a Dutch colonial-era term for the royal House of Orange-Nassau, with "pekoe" being a Chinese-derived word for the finest leaf.
• OP (Orange Pekoe) — even more basic, larger leaves.
• BOP (Broken Orange Pekoe) — leaves that have been broken during processing. Smaller, faster-steeping, often used in tea bags.
• Fannings and dust — the smallest particles, used almost exclusively in commercial tea bags.

You might also see a number appended (FTGFOP1, FTGFOP2, etc.), which is a sub-grade within the grade. The "1" is usually considered better than the "2."

Here's the thing: this whole grading system is based on leaf appearance, not flavor. A FTGFOP1 tea and a TGFOP1 tea from the same garden, picked the same day, will taste essentially identical in the cup. The grading is about what the leaves look like when you open the tin, not what they taste like when you brew them.

For most drinkers, this means: don't pay extra for FTGFOP over GFOP unless you care about the visual experience of opening the tin. If you care about the cup, focus on flush and origin.

The exception is BOP — "broken" matters for taste because broken leaves expose more surface area to the water and steep faster. A BOP tea will be stronger and more astringent at the same steep time than a whole-leaf OP from the same batch. This is why "broken" teas work for tea bags and whole-leaf teas work for brewing loose.

If you're buying loose leaf tea and the bag says "tgfop1," what you actually have is a higher-grade-looking version of whatever tea you were going to buy anyway. Don't let the abbreviation change your decision.

Origin and garden: the part that actually matters

The single most useful piece of information on a tea label — and the one most often missing or buried — is the specific garden or estate where the tea was grown, plus the region.

For Darjeeling, the gardens are individually named and have distinct reputations. Castleton, Makaibari, Margaret's Hope, Thurbo, Singbulli — each one produces tea with slightly different character because of microclimate, elevation, and processing tradition. A first flush Castleton will taste different from a first flush Margaret's Hope, even at the same flush and the same grade.

For other regions, the system varies:

• Assam (India): most teas are sold by district rather than garden, but the better ones name the estate. Second flush Assams are the base of most English breakfast blends.
• Ceylon (Sri Lanka): most teas are sold by district (Nuwara Eliya, Dimbula, Uva, Ruhuna) plus elevation. District matters more than estate name for most Ceylons.
• Chinese teas (Keemun, Lapsang Souchong, etc.): sold by region and sometimes by village. The regional name is the brand.
• Japanese teas (Sencha, Gyokuro, Hojicha): usually sold by region (Uji, Shizuoka, Kagoshima). Within region, single-cultivar teas are increasingly common and matter for taste.
• Taiwanese oolongs: sold by region (Alishan, Lishan, Dong Ding) plus cultivar. Region + cultivar is the meaningful identifier.

For most loose-leaf drinkers, origin-and-region is the most important piece of information on the label. Flush is the second. Grade (FTGFOP etc.) is third and probably doesn't matter for the cup.

If a tea label doesn't tell you where the tea was grown — just "black tea" or "finest blend" — that's a signal. It's not necessarily a bad tea, but it's not an honest one either.

If you want a deeper walk through what makes Darjeeling different from Assam different from Ceylon — and why our single origin guide walks through the parallel logic for coffee, but the same principles apply to tea — that's a longer read for another post.

The other terms you'll see

A few other labels you'll encounter, briefly:

• Orthodox manufacture — the traditional rolled-leaf method. The alternative is CTC (Crush, Tear, Curl), which produces smaller, more uniform particles used in most tea bags. Orthodox whole-leaf teas look like, well, leaves. CTC teas look like tiny pellets. For loose-leaf drinking, you almost always want orthodox.
• Single garden / single estate — tea from one named location, as opposed to a blend of teas from multiple gardens. Single-estate is more expensive and more traceable. Blends are often better-balanced cups; single-estates are more distinctive.
• Biodynamic / organic — farming certifications, similar to coffee. Worth what the certification costs you; the cup quality is somewhat independent of farming method.
• Lot number — the specific batch identifier. If a tea shop lists the lot number on the bag, that's a good sign — it means they're tracking specific harvests and can tell you which year and which flush the tea came from.
• The empty-marketing-words category — descriptors that signal high quality without telling you anything specific. Words like the ones on the front of a hotel mini-shampoo bottle, applied to tea. Most labels in our experience that lean on these words are hiding the fact that they can't tell you which garden or flush the tea came from. If a tea label leans on these words and doesn't tell you the garden, ask.

For more on why we avoid the empty-marketing-words pattern and how we describe our own teas, our packaging piece walks through the labeling choices we make for the same reason.

The plain-English version

If you only remember three things from this post, make them these:

1. Flush tells you when the tea was picked. First flush is brighter and more floral; second flush is fuller and more amber. For Darjeeling especially, flush changes the cup more than anything else on the label.
2. Origin (or garden, or estate) tells you where. A specific named garden in a specific region produces a more traceable, more distinctive cup than a generic "Darjeeling" or "Assam" label.
3. Grade (FTGFOP etc.) tells you how the leaves look, not how they taste. Don't pay extra for grade alone unless you care about the visual experience of opening the tin.

Everything else on the label is either marketing copy or specialty terminology you'll learn over time as you drink more loose-leaf tea. None of it needs to be intimidating. The vocabulary is dense, but the actual decision-making is simpler than it looks.

Brew slow. Sip slow. 🍵

P.S. We don't currently stock a single-garden Darjeeling or Assam — our tea lineup is matcha and herbal-based, which is a different category entirely from the orthodox black teas this post discusses. If you're looking for what we do drink, our hibiscus iced tea and caffeine-free herbal tea guides cover that side of the catalog. We wrote this post because the vocabulary on tea labels is genuinely hard to decode from the outside, and getting the language right makes buying tea — from us or from anyone else — easier.
