Pacific Northwest tea blenders: sourcing and release models
Pacific Northwest tea blenders in Portland and Seattle differ on leaf sourcing, batch size ranges and release models, with lot dating that follows each model.
What to take away
- Pacific Northwest tea blenders in Portland run smaller, more frequent batches and lean on dried herb from Willamette Valley and Columbia Gorge growers.
- Seattle blenders run larger import-led lots, tied to garden harvests or held in a fixed core catalog.
- Lot dating follows that splitseasonal Portland blends by blend date, Seattle import lots by base leaf harvest plus blend date.
- Teabox is an India-based seller with a US presence, not a Seattle blender.
- No blender posts batch weights, so ask for the batch number, the base lot and a retained sample.
The short answer on batch size and release cadence
Portland blenders typically build a seasonal blend in 3 to 10 kg lots, monthly. Seattle import-led blenders typically build 25 to 50 kg lots twice a year. Neither model is better. They answer different buyers.
Those are type ranges, not company disclosures. Landed cost per kilo decides which model a buyer can use, and US import duties and HTS codes explains what sits inside that number.
Batch size and release cadence
Typical batch size
- Portland, seasonal
- 3 to 10 kg
- Portland, menu-led
- 10 to 25 kg
- Seattle, import-led
- 25 to 50 kg
- Seattle, core catalog
- 40 kg and up
Release model
- Portland, seasonal
- Core plus seasonal drops
- Portland, menu-led
- Broad catalog, periodic new blends
- Seattle, import-led
- Harvest-driven releases
- Seattle, core catalog
- Fixed core, year round
Lot dating
- Portland, seasonal
- Blend date and base lot
- Portland, menu-led
- Blend date
- Seattle, import-led
- Base leaf harvest and blend date
- Seattle, core catalog
- Blend date and batch number
Cadence splits the same way: a seasonal Portland house may ship four drops a year, a Seattle core catalog two large runs.
Portland blenders and their core lines
Portland's blending trade grew out of tea rooms and retail counters that added blending in the back. Four names matter for wholesale.
Smith Teamaker runs a fixed core plus limited seasonal releases. Tao of Tea follows garden harvests, so batch sizes move with what the garden sends. Jasmine Pearl Tea Company keeps a stable catalog with periodic additions. Townshend's Tea Company runs a broad tea house menu, which pushes batch sizes up.
Menu breadth sets the number. A house holding forty blends cannot run each one at 3 kg. Read how American tea brands actually get made to see how one garden and one roast profile shape a whole line.
Most blenders in both cities buy base leaf by sample through importers in Seattle, Portland and Los Angeles, or direct from gardens in Taiwan, Japan, India and China.
Seattle blenders and the Teabox question
Seattle's trade grew alongside coffee roasting and import warehousing.
Miro Tea in Ballard runs a deep single-origin catalog with frequent small releases, which keeps batch size moderate and lot count high. Vital Tea Leaf builds on Chinese and Taiwanese styles and releases by garden lot. MarketSpice sets batch sizes by year-round demand on a flavored core.
Teabox is often grouped with those three. It should not be. Teabox is India-based with a US presence, and its leaf comes from Indian gardens, so first flush and autumn flush are separate releases with separate lot codes.

Local herb sourcing in Oregon and Washington
Local herb sourcing is real in both states, but small. Willamette Valley and Columbia Gorge growers sell dried mint, lemon balm, chamomile, lavender and rose to blenders by the pound.
A local grower gives a blender a named farm and a harvest week, which a commodity import cannot match. The tradeoff is supply: a bad mint year means no mint, so blenders split the buy between two growers.

Ask for the harvest week, the drying method and pesticide testing. The USDA's local and regional food market news lets a buyer check whether a quoted herb price sits near the market.
Dried herb for blending is food, not nursery stock, so food safety rules apply. Live tea plant material falls under Oregon Department of Agriculture plant health rules instead.
How a blender sets, dates and repeats a batch
How a blender sets a batch
- Set the batch weight at the smallest amount that still blends evenly: 3 kg for fine cut leaf with powdered herb, 10 kg for whole leaf with whole flower.
- Record the base lot from the importer or grower, with the garden and the harvest week.
- Cup the new batch against a retained sample of the previous one.
- Assign a lot code carrying the base lot, the blend date and the batch number.
- Adjust the ratio or shorten the sale window when the base leaf has faded.
How a batch is set
- Choose base leaf, confirm harvest date and grade
- Weigh base and inclusions to recipe percentages
- Blend in drum or by hand, rest 24-72 hours
- Cup rested blend against previous lot
- Assign lot code, record weight, date, base lot
ASTM's tea testing standards summary describes the lab checks on moisture and caffeine that confirm what a lot contains.
Lot dating and what it proves
Lot dating varies. Some blenders date by blend date, some by base leaf harvest. A useful code carries both.
Without the base lot, a buyer cannot trace a fade back to the leaf. That is the lot code and fade curve discipline a retailer needs before reordering.
Cost: what a larger lot buys
A 40 kg buy spreads importer fees and freight across more kilos than four 10 kg buys. That is why a Seattle core catalog can hold a price for a year while a Portland seasonal line reprices with each drop.
Hand-picked leaf costs more per kilo, so a small batch carries a higher unit cost.
Example: seven questions before a standing order
Seven questions before a standing order
- What is the batch weight, and does it change between releases?
- Which base lot, garden and harvest week is in the current batch?
- Does the lot code carry the blend date and the batch number?
- Will you retain a sample of the first order for cupping?
- What happens if a base lot fails or fades?
- How many releases a year, and on what dates?
- Which blends are core and which are limited?
Questions before a standing order
- What is the batch size, and does it change by season?
- What does the lot code containbase lot, blend date, batch number?
- Which base leaf garden and grade is in the current lot?
- Which local herb growers supply the inclusions, under what contract?
- What is the release modelcore, seasonal, harvest-driven or limited?
- How do you cup a new batch against the retained sample?
- What is your lead time if a base leaf lot is delayed?
A blender who cannot answer the first three cannot hold a spec. A standing order is a guess.
