The Science Of Coffee: Unraveling The Mystery Of Bunn's Hot Water Reservoir

The water in a Bunn coffee pot is kept at an ideal brewing temperature of 200°F, which gives the coffee a rich, robust flavour with zero bitterness. The water is maintained at this temperature by a stainless steel internal hot water tank, which is always ready to brew a pot of coffee quickly. The tank holds 70oz of water and is unique to Bunn coffee makers, setting them apart from other home coffee makers.

The water in a Bunn coffee pot is kept at 200º F

The Bunn Speed Brew, for example, uses a commercial-grade stainless steel internal hot water tank that keeps 70oz of water always hot and ready to brew. Bunn is the only company that uses a water reservoir to keep water hot and on standby, so you don't have to wait for your coffee. This is in contrast to other home coffee makers, which use a "burp and boil" method, heating water after it is poured in and "burping" it over the coffee grounds in spurts as it boils.

Maintaining the water at 200º F is important because it is the temperature at which coffee grounds are exposed to water for the perfect length of time, resulting in a rich, robust flavour with zero bitterness. It is also the temperature that allows the grounds to be constantly kept afloat and mingling throughout the brewing process, which is essential for a balanced flavour.

The Bunn Speed Brew's hot water tank is always ready to brew, so you can have a cup of coffee in just a few minutes. This is ideal for those mornings when you wake up late and need a coffee in a hurry!

Bunn coffee pots are always ready to brew

The Speed Brew model, for example, has a commercial-grade stainless steel internal hot water tank that keeps 70oz of water hot at all times. This means you can brew up to 10 cups of coffee in about four minutes, and as little as 20oz in about two minutes. The water is kept at approximately 200º F, which is the commercially recognised ideal brewing temperature. This is a key feature of Bunn coffee makers, as it ensures the coffee grounds spend the right amount of time in contact with hot water, resulting in a balanced flavour.

The Bunn BTX Thermal Carafe Coffee Brewer also keeps water hot and on standby. When you first set it up, you add up to 10 cups of cold water to the reservoir and turn the power on. It takes about 15 minutes to heat the water initially, and then it stays hot and ready until you need to brew. The BTX model is the only one that uses a water reservoir to achieve this.

The Speed Brew model also has a unique sprayhead design that showers the entirety of the coffee grounds, ensuring thorough saturation and optimum flavour and aroma extraction. This is in contrast to the "Burp and Boil" method used by other coffee makers, which can result in inconsistent spurts of boiling water and over-extracted or under-extracted grounds.

With Bunn coffee pots, you can be sure that you're getting a well-engineered machine that delivers a great-tasting cup of coffee, quickly and conveniently.

The water reservoir keeps water hot and on standby

The water reservoir in a Bunn coffee pot keeps water hot and on standby, ready to brew a fresh pot of coffee at a moment's notice. This is a unique feature of Bunn coffee makers, modelled after commercial coffee makers, and it's what sets them apart from other home brewers. The water reservoir ensures that you don't have to wait the usual amount of time associated with other coffee machines.

When you first set up your Bunn coffee maker, you add cold water to the water reservoir and turn the power switch on. It takes around 15 minutes to heat the water initially, and this water will stay hot and ready until you need to brew a pot of coffee. To begin brewing, simply add cold water to the reservoir, which displaces the hot water, sending it instantly to the filter basket where it infuses with your ground coffee. The freshly added water is then heated for the next round of coffee brewing.

The water reservoir in Bunn coffee makers holds 70oz of water and maintains a temperature of approximately 200º F, which is the commercially recognised ideal brewing temperature. This is in contrast to other home coffee makers, which use a "burp and boil" method, heating water after it is poured in and spurting it over the coffee grounds in bursts as it reaches boiling point (212º F). The "burp and boil" method can result in over-extraction and a bitter-tasting cup of coffee.

The water reservoir in Bunn coffee makers ensures that the water is always at the ideal temperature and that brewing can begin immediately. The temperature-controlled water passes over the grounds in one consistent flow, preventing over-extraction and ensuring a good, balanced cup of coffee.

The water tank is made of stainless steel

The water tank of a Bunn coffee pot is made of stainless steel. This material is known for its durability and ability to withstand high temperatures without warping or corroding. It is an ideal choice for a coffee pot as it can maintain the optimal temperature for brewing, ensuring a consistent and efficient brewing process.

One of the key advantages of a stainless steel water tank is its ability to retain heat. Stainless steel is an excellent thermal conductor, allowing the tank to quickly reach and maintain the ideal brewing temperature of approximately 200°F. This ensures that the water is always ready for brewing, eliminating the wait time typically associated with other home brewers.

The stainless steel construction also contributes to the overall durability of the Bunn coffee pot. Stainless steel is known for its strength and corrosion resistance, making it a durable choice for the water tank. It can withstand the constant heating and cooling cycles without warping or cracking, ensuring a long-lasting and reliable performance.

Additionally, stainless steel is a safe and non-reactive material for storing water. It does not leach harmful chemicals or affect the taste of the water, ensuring that the coffee brewed is of the highest quality. The smooth and non-porous surface of stainless steel also makes it easy to clean and maintain, preventing the buildup of limescale and other impurities.

The choice of stainless steel for the water tank reflects Bunn's commitment to quality and performance. By utilizing this durable and efficient material, Bunn coffee pots can deliver consistent brewing results and a superior coffee experience. The combination of style, functionality, and attention to detail sets Bunn coffee pots apart in the world of coffee brewing.

The water is heated in under 15 minutes

The BUNN Speed Brew is a unique home coffee maker with a commercial-grade stainless steel internal hot water tank that keeps 70oz of water hot and ready for brewing. This means that whenever you want coffee, the Speed Brew can start the brewing process immediately. The water in the tank is kept at approximately 200º F, the commercially recognised ideal brewing temperature. This is in contrast to other home coffee makers that use a "burp and boil" method, which heats water after it is poured in, leading to inconsistent spurts of boiling water over the coffee grounds.

The BUNN Speed Brew's tank is always full of water at the ideal brewing temperature, so brewing can begin as soon as cold water is added. This is because the cold water displaces the hot water in the tank, sending it to the filter basket where it diffuses through the coffee grounds. The water temperature is regulated by a thermostat, ensuring the water is kept at the optimum temperature for brewing.

The BUNN Speed Brew is designed to be left on at all times so that the hot water tank can maintain the optimal brewing temperature. This means that when you wake up in the morning, you can brew a travel mug of coffee in around two and a half minutes. The initial setup of the machine takes about 15 minutes to heat the water, and the machine should be allowed to heat for 15 minutes if it has been turned off for an extended period.
