Bonavita Cosmopolitan 1.0L Variable Temperature Gooseneck Kettle

The Bonavita Cosmopolitan is a 1.0L variable temperature gooseneck kettle that brings genuine brewing precision to everyday use — with six programmable presets, a sleek glass touch panel, and a Strix-controlled heating system built for reliability.

Precision Temperature Control

The Cosmopolitan adjusts in 1-degree increments from 60°C to 98°C (140°F to 208°F), giving you the accuracy to match water temperature to roast level and brewing method. Six programmable preset temperatures let you save your most-used settings and recall them with a single touch — no scrolling through every degree each morning. A real-time temperature display keeps you informed throughout the heating process.

Gooseneck Spout & Pour Control

The precision gooseneck spout delivers a steady, controlled stream suited to pour-over and manual brewing methods. The ergonomic handle provides a balanced, secure grip through longer pours, and the 360° cordless swivel base gives full freedom of movement on the worktop.

Build & Safety

The Cosmopolitan uses a UK Strix thermostat — the same component trusted by many premium kettle brands — alongside a 304 stainless steel body, BPA-free virgin plastics, and boil-dry protection with auto shut-off. At 1,200W it reaches boiling in around five minutes. Once at temperature, the heat-and-hold function maintains your setpoint for up to 60 minutes. A built-in count-up timer lets you track your brew without reaching for your phone.

Available in Black and White.

Frequently Asked Questions

What is the Bonavita Cosmopolitan gooseneck kettle? The Bonavita Cosmopolitan is a 1.0L variable temperature electric gooseneck kettle designed for pour-over and manual coffee brewing. It features 1-degree temperature precision between 60°C and 98°C, six programmable presets, a glass touch panel, 60-minute heat-and-hold, and a precision gooseneck spout — a well-specified brewing kettle at a practical price point.

What temperature should I brew pour-over coffee at? Most pour-over recipes call for water between 90°C and 96°C, depending on roast level. Lighter roasts generally benefit from higher temperatures (93–96°C) for full extraction, while darker roasts often taste cleaner brewed slightly lower (88–92°C). The Cosmopolitan's 1-degree increment control lets you dial in the exact temperature your recipe calls for every time.

What are the 6 preset temperatures on the Bonavita Cosmopolitan? The Cosmopolitan allows you to save up to six custom temperature presets, recallable with a single touch. This is particularly useful if you regularly switch between different coffee types, roast levels, or brewing methods — or if you brew both coffee and tea and want each at its ideal temperature without manually adjusting each time.

How does the heat-and-hold function work? Once the kettle reaches your chosen temperature, heat-and-hold maintains that temperature for up to 60 minutes, reheating as needed to hold the setpoint. This is ideal for brewing multiple cups in sequence or ensuring your water stays ready throughout a longer brewing session.

How does the Bonavita Cosmopolitan compare to the Fellow Stagg EKG? Both are 1,200W variable temperature gooseneck kettles with 60-minute hold and real-time temperature displays. The Bonavita Cosmopolitan's key advantages are its larger 1.0L capacity, six programmable presets, and lower price point. The Fellow Stagg EKG counters with a wider temperature range (57°C vs 60°C minimum), a built-in brew stopwatch, and a more premium analogue aesthetic. The Cosmopolitan is the stronger everyday choice; the Stagg EKG appeals to those who also want a design statement.

Is the Bonavita Cosmopolitan suitable for tea? Yes. The 60°C–98°C range covers oolong (80–90°C), black tea (95–98°C), and most herbal infusions. For green and white teas that typically brew at 60–75°C, the Cosmopolitan's 60°C lower limit gives just enough range, though the Brewista Artisan's wider 40°C–100°C range offers more headroom for delicate teas.
