Making Perfect Coffee – The Bunn Coffee Machines Way

Bunn has been synonymous with great coffee for decades. Ever since their introduction in 1963, Bunn coffee machines have set the standard for commercial pour-voer coffee systems. Bunn has been an innovator in the coffee industry since 1957 when they started making a revolutionary paper filter. They were already well-known in the coffee and restaurant industry when they introduced the Bunn Model X, the very first Bunn coffee machine. In 1973, Bunn made coffee history again with the first drip coffee maker for home use. Their home drip coffee maker started a revolution in the industry and for the past forty years, drip coffee makers have held the largest market share of all types of coffee makers in home use.

Bunn didn’t stop innovating with the drip and pour-over coffee makers, though. In 1990, they patented the first brewer to grinder interface so that Bunn coffee machines could grind and brew consistently great coffee every time. In 1997, Bunn took a stand against burned coffee with their Soft Heat system to keep coffee warm on the burner without overheating it. In 2001, Bunn introduced yet another innovation – the BrewWise system that saves individual customer profiles so that everyone in the house can have their coffee to their taste – or you can brew coffee just the way you like it for breakfast all the way to dessert coffee. With all that history of innovation and coffee goodness, you’d guess that the makers of Bunn coffee machines have some good advice for brewing coffee – and you’d be right. Here are some great tips for making excellent coffee from the makers of Bunn coffee machines.

Tips for Brewing Great Coffee from the Makers of Bunn Coffee Machines

Start with great tasting water. Believe it or not, hard water makes the best tasting coffee. Soft water doesn’t extract coffee flavor from the beans as well as harder water – but hard water can be rough on your coffee machine. You can use a water filter to remove most of the impurities from water, or use spring water. Skip the distilled water, though. It makes coffee that tastes flat.

Measure the coffee. Most of us here in the U.S. are accustomed to drinking weak brew made with too little coffee. Bunn recommends that you measure a full tablespoon for every five ounces of water. You’ll probably be shocked at how much coffee that actually is the first time you measure that out into your coffee basket, but the taste will convince you that this is what coffee is meant to taste like.

Keep it clean to make it great. Coffee oils build up on glass and metal and can get rancid quickly. Clean equipment makes the best coffee because there are no old coffee oils hanging around to spoil the flavor. Clean the glass decanter after every pot. Toss out the filter and grounds the moment the brewing is finished to keep it from dripping into the pot.

Clean the machine routinely following manufacturers instructions to remove coffee oils, lime scale and mineral deposits.

Use the right size disposable coffee filters. If your coffee filters are too small, grounds may escape into the coffee. If they’re too large, water will wick up above the filter basket rather than dripping over the coffee as it should. Bunn makes paper filters that are perfectly sized to fit all of their Bunn coffee machines.

Serve fresh-brewed coffee immediately. If you wait longer than twenty minutes to drink brewed coffee, it will begin to lose its flavor. If you won’t be drinking it that soon, you can hold it in a thermal carafe for up to sixty minutes before it starts to lose its flavor.
