The buying question

Should you automate steeping inside the kettle, or keep brewing separate and control the pour yourself?

Breville adds a moving tea basket and a larger, separately limited tea batch. COSORI supplies a 0.8 L gooseneck water kettle, leaving the brewing vessel and technique to you.

Quick verdict

Choose Breville Tea Maker BTM800XL if

  • You want automatic lowering and raising of the tea basket.
  • You need a tea batch beyond the COSORI’s 0.8 L water capacity and accept the separate glass-jug and accessory cleaning.

Choose COSORI CO108-NK (Matte Black) if

  • You prefer managing your own pours and a separate brewing vessel.
  • Your usual water batch fits within 0.8 L and the five fixed presets suit your routine.

When the recommendation changes
  • A recipe needing more than 0.8 L of water changes whether the COSORI can handle it in one fill.
  • Wanting the appliance to move the tea leaves into and out of the water favors Breville.
  • A dishwasher-only cleaning routine fits neither entire kettle.

The differences that matter

Steeping Workflow Or Pour Over Control

Breville Tea Maker BTM800XL

The Tea Maker lowers and raises its tea basket automatically. Tea-type and strength presets can be adjusted for temperature and brew time; it also has a separate hot-water mode.[1, 2]

COSORI CO108-NK (Matte Black)

The CO108-NK heats water using five fixed preset buttons. Its manual describes pouring from the gooseneck into a separate coffee brewer; the kettle does not perform that pouring or brew timing for you.[3, 4]

What this changes: Choose Breville to automate the loose-leaf steeping step inside its jug. Choose COSORI when you want to manage a separate brewing vessel and the pours yourself. Neither design proves better flavor or extraction.[1, 2, 3, 4]

The better fit depends on your priorities

Batch Size And Jug Care

Breville Tea Maker BTM800XL

Brewing tea uses the 1200 mL TEA MAX line. The manual separately lists 51 oz for WATER MAX; that larger fill is for water heating, not a tea batch.[1, 2]

COSORI CO108-NK (Matte Black)

The water capacity is 0.8 L. Stay below MAX; the heating instructions require at least 118 mL. A separate brewer holds the coffee or tea you prepare.[3, 4]

What this changes: Check the amount of water your usual recipe needs before buying. A batch requiring more than 0.8 L fits outside the COSORI single-fill capacity, while Breville still requires its lower tea limit for tea. These are fill limits, not guaranteed served volumes.[1, 2, 3, 4]

The better fit depends on your priorities

Best for your routine

Loose-leaf tea with automated basket movement

Best fit: Breville Tea Maker BTM800XL

Based on listed features, not comparative testing.

Breville automates that steeping step and accommodates tea filling up to its 1.2 L mark. You still load the leaves and water, serve the tea and clean the jug and basket.

A separate pour-over brewer with a modest water batch

Best fit: COSORI CO108-NK (Matte Black)

Based on listed features, not comparative testing.

COSORI’s documented gooseneck routine matches manual pouring into a separate brewer. Allow for the 0.8 L fill limit and cleaning that brewer as well as the kettle.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If Breville costs more, its automatic tea basket and larger tea fill are concrete reasons to consider the premium. If you will brew separately anyway, decide whether those functions would be used before paying for them.

There is not enough verified price history here to recommend buying now or waiting.

Community discussions

Questions and individual experiences add context, not controlled-test results, failure rates, or owner consensus.

Using CO108-NK presets and temperature hold

The discussion names CO108-NK and asks about presets, holding hot water and the small spout’s pour rate. Replies include other kettles, and one temperature comment is truncated. It can help you consider whether fixed presets and a gooseneck suit your routine; it does not establish accuracy, ease of handling or durability.

Limitations

  • Pickoryx has not tested these kettles. No boiling-speed, temperature-accuracy, flavor, extraction, reliability or cleaning-time winner is established.
  • This comparison covers the US BTM800XL and original CO108-NK. Features from a compact Tea Maker or COSORI smart/app model are not interchangeable.
  • Capacity figures describe permitted filling, not a guaranteed amount in your cup. Follow the correct tea or water mark.

Questions shoppers ask

Can the whole kettle go in the dishwasher?

No. Breville allows its jug lid, tea basket, basket lid and scoop in the dishwasher, but the glass jug must not be immersed. COSORI instructs you to wipe its kettle and base, keep the electrical connection dry and never immerse either. A separate brewer also needs its own cleaning.

Is scheduled brewing the same as keeping water hot?

No. Breville’s Auto Start begins a loaded tea or water cycle at the selected time. COSORI’s HOLD TEMP is enabled while heating and maintains the selected water temperature for up to 60 minutes; leaving it off the base for 60 seconds ends the mode. Neither feature promises your separate coffee or tea recipe will finish at a particular time.
