Loose-leaf tea · Dubuque, Iowa

A quiet cup, poured slowly, for the people who notice.

Byzanteaum is a small tearoom on the Dubuque riverfront where we hand-weigh single-origin leaves, heat the water to the leaf, and pour one cup at a time. No syrups. No rush. Just the leaf, the kettle, and a few minutes that belong entirely to you.

— est. for the ritual —

Loose-leaf oolong spilling from a wooden scoop onto a linen cloth, steam rising in warm side light.

This week's pour A rolled oolong from the hills above Anxi — honey, orchid, a finish like warm stone.

What we pour

Three ways to meet the leaf.

From a quick counter cup to a private tasting for six, every pour at Byzanteaum starts with the same question — what is this leaf asking for today?

A barista's hands pouring hot water from a gooseneck kettle into a glass teapot, leaves unfurling inside.

The Counter Pour

Sit down. We'll bring the kettle.

Pick a tea from the wall of glass jars and we'll brew it table-side in a glass teapot — water at the leaf's temperature, leaves timed on a small brass clock, a second steep on us if you'd like.

Take-home leaf

Weighed fresh from the jar into a lined pouch with steeping notes. Single servings, 50g tasting pouches, or full tins for the regulars. Tell us what you've been drinking and we'll suggest what to try next.

Subscription · the slow year

A different single-origin tea arrives at your door each month — six shipments over six months, with brewing guides and the story of where it came from. Skip a month, pause for travel, gift the rest.

Private tastings

For two to six guests. Three flights — green, oolong, dark — paired with simple sweets. We host in the back room after hours, walk you through each leaf, and send everyone home with the one they loved.

Teaware & ritual objects

Glass teapots, yixing-style clay, simple brass scoops and unbleached linen towels. Pieces we've used for years and trust enough to hand you. If it lives in the shop, we'll show you how to care for it.

Our story

A small room, built around one good leaf.

Byzanteaum began as a folding table at the Dubuque Farmers' Market — a single kettle, four jars, and a notebook of which leaves our regulars kept coming back for. The notebook grew. The table moved indoors.

Today we carry a focused shelf of single-origin teas: greens, oolongs, blacks, whites, and a few puerhs, all from farms we can name. We taste every new lot before it goes on the wall. If a tea doesn't earn its place at three different steepings, it doesn't join the shelf.

The room itself stays small on purpose. Eight seats at the counter, four at the window table, and the back room for tastings. We are not trying to be the biggest tearoom in Iowa. We are trying to pour a really good cup, slowly, for the people in front of us.

Why Byzanteaum

Small on purpose. Careful by default.

Any shop can sell you tea. The reason to come in, sit down, and let someone else pour it for you is harder to fake.

✦

Single-origin, named farms

Every tea on the wall comes from one place, one season. We can tell you the region, the picking date, and often the family that picked it.

◐

Tasted before it's sold

We brew every new lot at three temperatures and three steep times before it ever reaches a jar. If it doesn't open up across the full range, we don't buy it again.

○

Water at the right temperature

Green teas don't like boiling water. Dark teas do. We heat each kettle to the leaf, not to the kettle. It's a small detail. It's the difference.

⌖

A place to sit, not just shop

Twelve seats, slow music, no televisions. The room is built so you can drink an entire pot without anyone asking if you'd like the check.

What to expect

From the door to the last sip.

If you've never been to a tearoom, here is exactly how a visit unfolds — no surprises, no ceremony you need to know in advance.

Come in and look around

No reservation needed for a single seat at the counter. Take a moment with the wall of jars — that's the whole menu.

ii.

Pick a leaf (or ask)

Tell us what you've been drinking, or what you've been tired of, and we'll point you to two or three jars to smell side by side.

iii.

Watch it pour

We brew table-side in glass so you can watch the leaves open. We talk you through what you're seeing, or we don't — your call.

iv.

Stay for the second steep

Good leaves change across three or four steeps. The pot is yours. Take as long as you'd like — we'll keep the water warm.

Do I need to know anything about tea to come in?

No. About half of our regulars started by telling us "I only really drink English Breakfast, and even that with milk." That is a perfectly good place to begin. We'll find you the next step from there.

Can I bring a group, or is the tearoom only for individuals?

Both work. Up to four people can sit together at the counter or the window table any time we're open. For five or more, or for tastings and small events, we open the back room by reservation. Send us a note through the form below and we'll find a time.

Do you sell tea by the cup to go?

Yes — we pour travel cups of any tea on the wall, brewed to the leaf's temperature in a take-out glass teapot you can keep or return. It takes us an extra minute or two. Worth the wait.

How should I store the tea I buy?

Away from light, away from heat, away from strong smells (coffee, spices, the inside of a working oven). Airtight in the pouch it came in is fine for a few weeks. For longer, a simple ceramic tin with a gasket — we carry a few in the shop.

Do you ship outside of Iowa?

Yes, within the continental United States. Leaves are sealed in foil and shipped in unbleached mailers the same week they're weighed. Shipping is calculated at checkout; orders over a certain amount ship free.

Are you actually a café, or just a tea shop?

Both, and neither. We are a tearoom first — a small room built around the act of pouring and drinking tea slowly. There is no espresso, no pastries made on-site, no wifi password taped to the counter. There is, however, excellent warm shortbread from a bakery two streets over, and the kind of quiet that is hard to find in Dubuque.

Get in touch

Send us a note. We'll write back the same afternoon.
