The 33 Unique FAQs About Coffee
What is the best temperature to brew coffee?
The optimal water temperature for drip coffee is 195-205F (91-96C). According to various study notes, colder water doesn’t extract enough caffeine/essential oils from the beans, and at any brewing temperature above 208F (98C), the acidity increases wildly[1].
How much caffeine is in decaf?
In the US, federal regulations require that to label coffee as “decaffeinated” it must have had its caffeine level reduced by no less than 97.5 percent[2].
Normally, many Arabicas are about 98.64% caffeine-free even before anything is done to lower the caffeine content. In other words, it is about 1.36% caffeine by weight. When 97% of the caffeine has been removed, only .0408 % of the coffee weight is caffeine, at this level, it is labeled “decaffeinated.
(1-98.64%) x (1-97%) = 0.0408%
How much coffee is equal to 100mg of caffeine?
In general, it is about 1 – 2 cups of regular coffee, assuming the cup size is 8 fl oz. On average an 8 fl oz regular steeped coffee has about 90+ mg of caffeine depending on the bean type and roast method.
Where did the term "cup of joe" come from?
A likelier theory is based on linguistics. This theory states that “Joe” is the simplified form of the word “jamoke,” which began as a nickname for coffee in the 19th century, a portmanteau of the coffee beans “Java,” and “mocha.” Therefore, “cup of jamoke” may have become shortened to a “cup of Joe.” [3]
What is the difference between arabica and robusta?
Arabica beans and robusta beans are two different species of coffee. They are the two primary species that find their way into the American cup. The general differences are the tastes and the conditions under which the two species differ in production[4].
Arabicas have a wider taste range, between varieties. They range in taste from sweet-soft to sharp-tangy. Their unroasted smell is sometimes likened to blueberries. Their roasted smell is perfumey with fruity notes and sugary tones.
Robustas’ taste range is neutral to harsh and they are often described as tasting grain-like, such as oatmeal. Their unroasted smell is often described as raw peanutty. Their roasted smell is often likened to burnt rubber.
Arabicas are delicate, they require cool tropical climates, lots of moisture, rich soil, shade, and sun. They are subject to attack from various pests and are extremely vulnerable to cold and bad handling.
Robustas are hardier plants, from their name you can figure out their hardier characteristics, capable of growing well at low altitudes, and less subject to problems related to pests and rough handling. They yield more pounds of finished goods per acre at a lower cost of production.
Just how much ground coffee do I need for X amount of liquid?
According to the Specialty Coffee Association of America (SCAA), a cup is defined as 6 ounces of water before brewing. This will produce 5.33 ounces of brewed liquid, or 125 ml & 110 ml for Euro-style makers.
The SCAA defines 10 grams or .36 oz per cup as the proper measure for brewed liquid if using American standards. If using Euro standards the measure is 7 grams per 125 ml.
Why do people put milk in their coffee instead of just drinking black coffee?
Putting milk in coffee is equivalent to making a cocktail, to make the drink more palatable. Here are some of the most common reasons:
- Reduces bitterness of the coffee.
- Adds sweetness.
- Enhance flavors.
- Creamier texture.
- Temperature control.
- Habit.
- Versatility.
- Health perception.

How early is considered too late in the afternoon to drink coffee?
There isn’t a universal cut-off time for afternoon coffee. Some people can drink coffee right before bed with no sleep issues, while others are wired for hours after. If caffeine keeps you up at night, avoid it later in the afternoon. If you go to bed early (around 10 pm), aim to finish your coffee by 2-3 pm to allow enough time for caffeine to clear your system. Many experts suggest stopping caffeine intake around 2 pm to ensure a good night’s sleep.
What is light roasts, medium roasts, medium dark roasts and dark roasts?
Light roasts
Medium roasts
Medium dark roasts
Dark roasts
Do darker roasts have more caffeine?
Most of the time dark roast is described as tasting more bitter than light roast. However, the bitterness of dark roasted coffee may be caused by the brewing time, the coffee-to-water ratio used, and the grind depending on the brewing techniques or machines.
The boldness of a dark roast often has been confused with the bitter sensation of an over-extracted brew. It’s important to differentiate bitterness from caffeine content. Most people would call a hot bitter coffee “strong”, just because of the bitterness and the high temperature associated with the sensation in the mouth and on the tongue as “strong”.
The truth is that caffeine content remains pretty much the same during each stage of the roasting process. The difference between roasts is taste, not the amount of caffeine. One of the possible facts that darker roasted may have more caffeine in a finished cup than a light roast is that people might likely use more dark coffee to brew a cup.
What is the difference between a blend and a single-origin coffee?
Single-origin coffees are sourced from a specific place and can be estates, family-owned farms, or communities served by farmers. Blends coffees from different places that combine to highlight certain distinct flavors.
What's the difference between breakfast blend coffee and house blend coffee?
Here are several key differences:
1, Roast,
Breakfast Blend: Typically a lighter roast, this results in a brighter acidity, lighter body, and more subtle flavors like citrus and floral notes. In one word, SOUR!
House Blend: Usually a medium roast, This leads to a fuller body, stronger flavor, and deeper notes like caramel, chocolate, and nuttiness. Another way to put it: less sour!
2, Caffeine Content,
Breakfast Blend generally has a higher caffeine content.
House Blend caffeine content varies depending on the specific blend but is typically lower than breakfast blends due to the darker roast.
Some brands may not strictly adhere to these typical characteristics, so it’s always good to read the description or ask about the specific blend before buying. As a personal preference, I just don’t like sour coffee, so I stay away from both breakfast blend and house blend coffees. I love French roast or dark roast coffee instead.

what is the difference in caffeine consumption between younger and older people?
- Generally, younger adults (20-40s) tend to consume more caffeine: Studies suggest their intake can be around 300-400mg per day, often from sources like coffee, energy drinks, and soda.
- Older adults (65+) tend to consume less: Their average intake typically falls around 200mg per day. This might be due to health concerns, changes in taste preferences, or simply consuming less overall.
- Older adults often show increased sensitivity to caffeine: As we age, our bodies metabolize caffeine slower, so the same amount can have stronger effects. This can lead to jitteriness, anxiety, sleep disturbances, or other sensitivities.
- Younger adults usually tolerate caffeine better: Their faster metabolism allows for quicker clearance, minimizing side effects.
Is it safe to use boiled water when making instant coffee? What are the potential consequences if boiled water is used?
Can long-term consumption of large amounts of caffeine lead to a decrease in dopamine levels and a need for higher doses to achieve the same effects?
- Caffeine’s Mechanism: Caffeine works primarily by blocking adenosine receptors in the brain. Adenosine typically slows down neural activity and makes you feel tired. Caffeine’s interference leads to increased neural activity and feelings of alertness.
- Dopamine Connection: The increased neural activity caused by caffeine also triggers a rise in dopamine, a neurotransmitter associated with pleasure, motivation, and reward. This is one of the factors that contributes to caffeine’s stimulating effects.
- Tolerance: With regular and high caffeine use, your brain adapts. It may produce more adenosine receptors or become less sensitive to dopamine, essentially trying to normalize its activity despite caffeine’s influence. This is called tolerance.
- Decreased Sensitivity: As your brain becomes less sensitive to both adenosine and dopamine, you start needing higher amounts of caffeine to achieve the same stimulating effects you once experienced with lower amounts.
- Decreased Sensitivity: As your brain becomes less sensitive to both adenosine and dopamine, you start needing higher amounts of caffeine to achieve the same stimulating effects you once experienced with lower amounts.
Important Considerations:
- Individual Variation: The degree to which caffeine affects dopamine systems can vary between individuals, influenced by factors like genetics and consumption habits.
- Withdrawal: If you abruptly stop consuming caffeine after prolonged heavy use, you can experience withdrawal symptoms like headaches, fatigue, and low mood. This is partly related to the temporary disruption of dopamine function.
- Dosage Matters: Moderate caffeine consumption is less likely to lead to significant dopamine-related issues compared to chronic consumption of very high doses.
What is the difference in caffeine consumption between younger and older people?
Generally, younger adults (20-40s) tend to consume more caffeine: Young adults’ caffeine intake can be around 300-400mg per day, often from sources like coffee, energy drinks, and soda.
Older adults (65+) tend to consume less: Their average intake typically falls around 200mg per day. This might be due to health concerns, changes in taste preferences, or simply consuming less overall.
Older adults often show increased sensitivity to caffeine: As we age, our bodies metabolize caffeine slower, so the same amount can have stronger effects. This can lead to jitteriness, anxiety, sleep disturbances, or other sensitivities.
Younger adults usually tolerate caffeine better: Their faster metabolism allows for quicker clearance, minimizing side effects.
It’s important to remember:
Moderation is key. Regardless of age, limiting caffeine intake and being mindful of individual sensitivities is wise.
Consult a doctor. If you have concerns about caffeine or experience negative effects, speak to your doctor for personalized advice.
What is the calorie count of a cup of non-dairy coffee creamer, such as International Delight?
The calorie count of a cup of non-dairy coffee creamer can vary depending on the brand and variety. For example, one cup (8 fl oz) of International Delight Original non-dairy coffee creamer contains 560 calories.
On the International Delight FAQ page, it mentions that “Regular varieties of International Delight creamer contain 35 calories per tablespoon.”
A tablespoon is 0.5 fl oz, so a cup of this creamer is equivalent to 16 tablespoons in volume, therefore it is about 560 calories in a cup of ID non-dairy creamer.
What is the difference between culinary-grade and ceremonial-grade matcha when making lattes?
When it comes to making lattes, both culinary-grade and ceremonial-grade matcha can be used, but there are some key differences to consider:
Flavor:
- Ceremonial: Characterized by a smooth, delicate, and slightly sweet flavor with subtle grassy notes. Less bitter than culinary grade.
- Culinary: Often bolder and slightly bitter, with earthier and stronger vegetal notes. Stands up well to milk and other ingredients.
Texture:
- Ceremonial: Finer grind, resulting in a smoother and creamier texture in your latte.
- Culinary: Slightly coarser grind, which might lead to a slightly grainy texture in your latte.

- Culinary: More affordable, making it a good choice for experimenting or everyday use.
Overall:
- Ceremonial: If you prioritize a refined and delicate matcha flavor in your latte and are willing to invest, this is the better choice.
- Culinary: If you don’t mind a slightly bolder flavor, and value affordability and versatility for other recipes, this is a good option.
Additional factors to consider:
- Sweetener: Due to its bitterness, culinary grade matcha might require more sweetener to achieve a palatable taste in your latte.
- Mixing: Ceremonial grade matcha might dissolve more easily in your latte due to its finer texture.
- Latte-specific matcha: Some brands offer matcha specifically designed for lattes, which blends the best aspects of both ceremonial and culinary grades.
