13 Frequently Asked Questions To Coffee Roasters

 coffee roasters Sydney

 

1. What does a coffee roaster do?

A coffee roaster transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste.

The vast majority of coffee is roasted commercially on a large scale, but small-scale commercial roasting has grown significantly. Some coffee drinkers even roast coffee at home as a hobby in order to both experiment with the flavor profile of the beans and ensure the freshest possible roast. 

 

2. What Happens During the Coffee Roasting Process?

Green coffee changes drastically during the roasting process.

When you roast coffee, moisture is forced out of the bean, causing it to dry and expand. During the process, some of the natural sugars are converted into CO2 gas while others are caramelized into some of the flavors that help form the complex flavors in the coffee.

When the process is complete, the green bean will transform into a brown bean that is about 18% lighter while being 50 to 100% larger. As soon as the roasting process is complete, the coffee begins to “Degas,” and in as little as a week or two, the roasted coffee will have already begun to lose some of its flavor and aromas.

3. How does roasting affect coffee flavor?

The degree to which coffee beans are roasted is one of the most important factors that determine the taste of the coffee in the cup.

Before roasting, green coffee beans are soft, with a fresh smell and little or no taste. The coffee roasting process transforms these raw beans into the distinctively aromatic, flavorful, crunchy beans that we recognize as coffeeOther factors, of course, enter into the complex equation that determines your coffee's taste. 

Two coffee varieties, from different countries of origin or grown in different environments, are likely to taste quite different even when roasted to the same level (especially at light to medium roast levels). 

The age of the coffee, the processing method, the grind, and the brewing method will also affect the taste. But the roast level provides a baseline, a rough guide to the taste you can expect.

 

Light Roasts

Light roasts are light brown in color, with a light body and no oil on the surface of the beans. Light roasts have a toasted grain taste and pronounced acidity. The origin flavors of the bean are retained to a greater extent than in darker roasted coffees.

Light roasts also retain most of the caffeine from the coffee bean. 

 

Medium Roasts

Medium roasted coffees are medium brown in color with more body than light roasts. Like the lighter roasts, they have no oil on the bean surfaces. However, medium roasts lack the grainy taste of the light roasts, exhibiting more balanced flavor, aroma, and acidity.

Caffeine is somewhat decreased, but there is more caffeine than in darker roasts. Medium roasts reach internal temperatures between 410°F and 428°F between the end of the first crack and just before the beginning of the second crack.

Dark Roasts

Dark roasted coffees are dark brown in color, like chocolate, or sometimes almost black. They have the sheen of oil on the surface, which is usually evident in the cup when the dark roast coffee is brewed.

The coffee origin flavors are eclipsed by the flavors of the roasting process. The coffee will generally have a bitter and smoky or even burnt taste. The amount of caffeine is substantially decreased.

To reach the level of a dark roast, coffee beans are roasted to an internal temperature of 465-480°F about the end of the second crack or beyond. They are seldom roasted to a temperature exceeding 490°F, at which point the body of the beans is thin and the taste is characterized by flavors of tar and charcoal.

  • As coffee roasts get darker, they lose the origin flavors of the beans and take on more flavors from the roasting process.
  • The body of the coffee gets heavier, until the second crack, where the body again thins.
  • Lighter roasts have more acidity than darker roasts.
  • Lightly roasted beans are dry, while darker roasts develop oil on the bean surface.
  • The caffeine level decreases as the roast gets darker.

Ultimately, it is all about the taste, the flavor, the aroma. You may prefer a lighter roast in the morning (with more caffeine) and a darker one later in the day. Coffee, including the optimal roast level, is a personal preference. What's yours?

4. Can you roast coffee at home?

One of the best ways you could ever hope to enjoy coffee is by roasting it yourself. When you roast coffee at home, you guarantee that every cup of coffee you make will be fresh and, with a little practice, you can ensure that it is roasted exactly to your taste.

7. What roast of coffee is the strongest?

This can be debated but caffeine level decreases as the roast gets darker meaning light is stronger. 


8. What coffee roast has the most caffeine?

There is a popular myth floating around that dark roasts have more caffeine than light roasts. Unlike the myth of the Loch Ness monster (oh, it's real), dark roasts do not have more caffeine than light roasts. 

Many coffee know-it-alls say that lighter roasts have the most caffeine, but they are wrong as well. Bean for bean, both roasts has about the same amount of caffeine, though it is a bit more complicated than that.

When beans are roasted, they lose some of their mass, so dark-roasted beans, which have been cooked longer, weigh less than light-roasted beans. Therefore, a pound of the dark roast will have slightly more beans than a pound of light roast.

Start small by offering your coffee blends to family and friends to sample, and see which ones they like best.  Then you can start selling your coffee to them. You can also offer your blends to local coffee shops and restaurants, or even your local flea market.

It’s a simple process with some necessary steps to note along the way to guarantee great results. These important steps hold true for every roasting method.

Let's take a quick look at what happens during roasting, and after roasting, so that you know what's going on while the magic is happening:

Roasting

  • Temperature: 350F to 500F is the widely accepted temperature range. This varies depending on the roasting method you’re using
  • Agitation: Your beans can never rest and roast! Constant stirring ensures an even distribution of heat, and thus an even roast
  • First Crack: After 3 to 5 minutes the beans will produce an audible crack. This crack indicates that your beans are lightly roasted and ideal for white coffee. This the minimum amount of time required to produce roasted beans. Continue roasting and agitating for darker roasts
  • Second Crack: After a few more minutes another crack is heard. This second crack indicates a medium roast. A few more minutes of roasting and your beans will be burnt and unusable. Experiment with times to find your favourite roast
  • Tip: We usually wait roughly 30 seconds after hearing the second crack
  • Cool Down: Transfer beans to a metal colander or baking paper to cool. Use two metal colanders (plastic can melt). Shake and transfer your roasted beans between colanders. This cools the beans quickly and removes the chaff.
    Spread evenly over the baking paper to substitute for a metal colander. This method is not as effective
  • Remove Chaff: Chaff is the dried husk of the coffee bean. It is very messy. Cool your beans down outside or in the sink to reduce clean-up
