WAVERLY, Iowa (AP) — Move over craft beer. There’s a new beverage brewing on the local scene.
Craft coffee is energizing java enthusiasts — like Erik Johnson of Waverly — to create their own coffee blends at home using a delicate roasting process.
“You can totally screw up a great coffee by poorly roasting it, and you can take a mediocre coffee and bring it to its highest heights,” Johnson told the Waterloo-Cedar Falls Courier.
Over the last decade Johnson has grown and matured his roasting techniques. The craftsmanship behind each cup of the centuries-old beverage considers the flavor and origin of each bean.
Along with his wife, Becky, the pair are sharing their creations with other coffee lovers at Thinkwell, an online ordering system where customers can purchase customized coffee beans.
Roasting raw coffee beans, also called green beans, physically and chemically changes their properties, which affects the aroma and flavor. Based on the belief coffee is an art and roasting is a skill, each batch is roasted differently and the final temperature is recorded.
“With each batch I am activating a part of my brain, my mind, my spirit that is creating,” Johnson said.
When ordering a particular style of coffee, the customer – whether they know it or not – is choosing coffee beans with a specific origin and roast temperature. For most mainstream coffee shops, roast styles are referred to as “light, medium or dark,” but not at Thinkwell.
Instead, it’s all about the finish temperature, which tells a story on its own. It’s the temperature recorded when a batch of beans is finished roasting. That number then becomes part of the batch’s name along with the beans’ country of origin. 418 Honduras signifies a darker coffee, while 391 Burundi refers to a lighter coffee.
For coffee aficionados, it’s easy to hone in on preferred tastes. For beginners, the website offers a survey to help customers find a blend that suits them best at thinkwell.coffee/customorder.
Typical coffee shop operations rely on replicating the flavor so the customer knows exactly what they’re getting.
“Ours is the exact opposite of that. Each batch is unique,” he said. “Even if I try to roast it the same way two times in a row, it’s not going to taste the same. It’s going to be in the ballpark and most people won’t notice that and that’s fine, but at the heart of it, it’s not the same.”
Erik began roasting coffee beans at home in an old popcorn popper about 10 years ago.
“When I found out I could roast at home a light bulb turned on in my head,” he said.
For the next several years, he acquired more knowledge and experience by working everywhere from small coffee shops to wholesale operations…
