Overview of the Kendal ZH-SCM11-FBA

The Kendal ZH-SCM11-FBA Glass Tabletop Siphon Coffee Maker is a modern interpretation of the classic siphon design. It features two heat-resistant borosilicate glass chambers, a sturdy stainless steel stand, a silicone gasket for a tight seal, an alcohol burner for heat, a reusable cloth filter, a coffee scoop, and a bamboo stirrer. With a 5-cup capacity, it’s perfect for both personal enjoyment and sharing with friends.

Unveiling the Science: How Siphon Coffee Makers Work

The magic of the siphon coffee maker lies in its ingenious use of basic physics principles, specifically vapor pressure and vacuum. Let’s break down the process step-by-step:

1. Heating and Pressure Build-up: As the water in the lower chamber (the “bulb”) is heated by the alcohol burner, it begins to transform into water vapor. This vapor increases the pressure inside the sealed lower chamber. Think of it like a crowded room getting hotter – the people (water molecules) start moving faster and pushing outwards.

2. Water Ascent: This increased pressure forces the hot water upwards through the siphon tube and into the upper chamber, where the ground coffee awaits.

3. Brewing and Infusion: The hot water saturates the coffee grounds, initiating the brewing process. This is where the extraction of flavors and aromas takes place. The water temperature, typically just below boiling, is ideal for extracting the desirable compounds from the coffee without burning it.

4. Vacuum Creation: Once most of the water has moved to the upper chamber, the heat source is removed. As the lower chamber cools, the remaining water vapor condenses back into liquid water. This condensation creates a partial vacuum in the lower chamber.

5. Coffee Descent and Filtration: The vacuum in the lower chamber draws the brewed coffee back down through the filter, leaving the coffee grounds behind in the upper chamber. The result is a clean, sediment-free cup of coffee.
   

Exploring the Features of the Kendal ZH-SCM11-FBA

Heat-Resistant Borosilicate Glass:

The upper and lower chambers of the Kendal ZH-SCM11-FBA are crafted from high-quality borosilicate glass. This type of glass is renowned for its exceptional thermal resistance, meaning it can withstand rapid temperature changes without cracking or shattering. Imagine pouring boiling water into a regular glass – it would likely shatter instantly. Borosilicate glass, however, can handle this with ease, making it ideal for the extreme temperature fluctuations inherent in the siphon brewing process. This durability ensures the longevity of the coffee maker and, more importantly, your safety. Beyond its thermal properties, borosilicate glass is also chemically inert, meaning it won’t react with the coffee or impart any unwanted flavors, preserving the purity of your brew. Its crystal-clear transparency allows you to witness the mesmerizing dance of water and coffee during the brewing process, turning coffee making into a captivating spectacle. This is the core of the first law of thermodynamics, which describes conservation of energy.

Sturdy and Elegant Stainless Steel Stand:

The Kendal ZH-SCM11-FBA features a robust stainless steel stand that provides a stable and secure base for the glass chambers. Stainless steel is known for its strength, durability, and resistance to corrosion. This ensures that the stand will remain sturdy and reliable over time, providing a safe platform for your brewing ritual. Beyond its functional role, the stand’s polished finish adds a touch of elegance to the overall aesthetic, making the coffee maker a stylish addition to any kitchen. The brown plastic handle is a bit of a letdown from a design perspective, but is functional and was likely a cost-saving measure.

Airtight Silicone Gasket:

A crucial component of any siphon coffee maker is the gasket, which creates an airtight seal between the upper and lower chambers. The Kendal ZH-SCM11-FBA utilizes a food-grade silicone gasket. Silicone is a remarkable material known for its flexibility, heat resistance, and durability. This ensures a tight seal, preventing any air leaks that could disrupt the pressure differential necessary for the siphon process to work correctly. The tight seal maintains the vacuum. The chemical inertness of silicone also means it won’t react with your coffee or impart any off-flavors.

Classic Alcohol Burner:

The Kendal ZH-SCM11-FBA comes with a traditional alcohol burner, providing a gentle and adjustable heat source. The beauty of the alcohol burner lies in its simplicity and control. By adjusting the wick’s exposure, you can fine-tune the flame’s intensity, allowing for precise control over the water temperature. This is important because different coffee beans and roasts may require slightly different brewing temperatures to achieve optimal flavor extraction. While some users, like reviewer N. Cole, prefer to upgrade to a butane burner for even greater control, the included alcohol burner is a perfectly functional and classic option. It is worth noting that one fill of ethanol will last for dozens of pots.

Environmentally Friendly Reusable Cloth Filter:

The Kendal ZH-SCM11-FBA includes a reusable cloth filter, offering an eco-conscious alternative to disposable paper filters. This filter is designed to effectively trap coffee grounds while allowing the flavorful oils and aromatic compounds to pass through, resulting in a richer, more full-bodied cup of coffee. As noted in several reviews, it’s crucial to rinse the filter thoroughly with water only after each use and avoid using soap, as any residue can taint the flavor of your coffee.

Convenient Accessories: Spoon and Stirrer:

To complete the brewing experience, the Kendal ZH-SCM11-FBA includes a plastic coffee scoop and a bamboo stirrer. The scoop helps you measure the correct amount of coffee grounds for your desired brew strength, while the stirrer allows you to agitate the coffee grounds in the upper chamber, ensuring even saturation and extraction. While simple, these accessories are thoughtful additions that enhance the overall usability of the coffee maker.

5-Cup Capacity: Perfect for Sharing or Savoring Solo:

With its 0.31-gallon capacity, the Kendal ZH-SCM11-FBA can brew approximately five cups of coffee, making it suitable for both individual enjoyment and sharing with friends or family.
