When preparing coffee, we know that there are a few different variables we can tweak in order to impact the flavor in the cup. We can play with brew temperature, pre-infusion timing, grind consistency, coffee dosage and water ratio, and each element will produce a different flavor nuance.
So we decided to play around with that! In this video, we take three different Brazen Brewers and we change up the grind consistency, coffee dosage, brew temperature and pre-infusion time, then taste them to see how they compare. Watch as we learn more about how changing these elements impacts our coffee.
If you drop serious coin on your home espresso setup, will there be a practical performance difference? What if you spend more on your espresso machine than your grinder or vice versa?
We asked Gail to test out an entry level (Capresso Infinity) and a prosumer (Mazzer Mini E) grinder with an entry level (Krups XP5280) and prosumer (Rocket Giotto Evoluzione V2) espresso machine to see how they compare. Do you get a better shot using a high end grinder with an entry level machine? What about an entry level grinder with a high end machine?

Studies have shown that men and women who are drinking six or more cups of coffee a day have a 10 (for men) and 15 (for women) percent lower risk of dying at an earlier age.
Historically, doctors have noted a correlation between caffeine and an increase in bad cholesterol, high blood pressure and the risk of heart disease; however, a recent study has revealed an interesting pattern: Drinking coffee may extend the overall lifespan in already healthy individuals.
A study held from 1995 to 2008 involving the National Institutes of Health and AARP members between the ages of 50 to 71 from all over the US has given researchers a better look at the possible health benefits of coffee. They made sure to exclude people who already had heart disease, a stroke or cancer or had too many or too few calories a day.
‘By 2008 about 52,000 had died. Compared to those who drank no coffee, men who had two or three cups a day were 10 percent less likely to die at any age. For women, it was 13 percent,’ revealed the study.
Since previous studies have suggested that coffee may have a part in heart disease, this study inspired Neal Freedman, nutritional epidemiology researcher at the National Cancer Institute, to consider another contributing factor. He noted that many who were at higher risk of death were coffee drinkers and tobacco smokers, too. ‘It was only after we took into account people’s smoking that the association, the inverse association, revealed itself,’ he said. ‘Smoking has a really strong association with death.’
In the end, Freedman’s study showed that those with healthy habits who drink six or more cups of caffeinated or decaffeinated coffee did cut the risk of dying but not to the extreme. Freedman couldn’t calculate the exact amount of extra life each cup can give you. However, he admits coffee drinkers were less likely to die from heart or respiratory disease, stroke, diabetes, injuries, accidents and infections. No effect was seen on cancer death risk, though.
So we’ll admit that we’ll grab that extra cup of java to increase the longevity of our lives, even if it’s only by a few percentage points, but a word of advice: More coffee does not mean you should pack on the sugar and cream.
As Dr. Frank Hu of the Harvard School of Public Health advises, ‘Watch the sugar and cream. Extra calories and fat could negate any benefits from coffee.’
Coffee was what kept me up during those late nights of studying in college; for expecting and new mothers, you’d think it would be their lifeline too! I figured caffeine was the fuel that helped them during long, sleepless nights with their newborns.
But to my surprise, drinking caffeine has been a concern for many mothers. It’s been believed that mothers should cut down on their coffee habit because of adverse affects that could affect the sleeping patterns of their bundles of joy. However, researches have found that coffee does not affect your child’s sleeping habits.
This doesn’t necessarily mean you can keep drinking that Grande Double Mocha you crave each morning, but studies have failed to show any heightened risk correlating between a mother’s caffeine intake and sleeplessness in her child.
Heavy coffee drinkers are defined as consuming about 300 milligrams or more of caffeine per day via coffee or any caffeinated beverage. “In 2010, the American College of Obstetricians and Gynecologists (ACOG) said that 200 milligrams of caffeine a day – about the amount in a 12-ounce cup of coffee — probably did not carry pregnancy risks.”
In an article in HealthDay, Brazilian researchers conducted an analysis of sleeping patterns of more than 4,200 infants until the age of 3 months. The mothers of these infants had light caffeine consumption before and after delivery. Led by Dr. Ina Santos of the Federal University of Pelotas in Brazil, the study was designed to analyze the possibility that caffeine linked to disrupted sleeping patterns in newborns and babies. Of the 4,200 babies, 885 mothers were interviewed after delivery and three months later to gauge their caffeine-drinking habits. Each baby was then examined after delivery and had follow-up exams three months later. Santos and her colleagues stated that all but one mother consumed caffeinated beverages.
Twenty percent of the mothers were considered to be heavy consumers and 14 percent had heavier caffeine consumption three months after giving birth. About 14 percent of the babies frequently woke up during the night. There was some indication that nighttime wake-ups were more prevalent with babies whose mothers were heavy caffeine drinkers during pregnancy and nursing, but Santos claims these numbers were still not significant.
‘Nighttime wakening among babies that age can be due to so many different things,’ Lona Sandon, a registered dietitian and assistant professor of clinical nutrition at the University of Texas Southwestern in Dallas said. ‘So to tease out caffeine’s role is going to be very difficult.’
Caffeine can cause sleep disruption among adults, but researchers aren’t finding any hard evidence that java consumption, at any particular level, is directly connected to the sleep pattern disruptions of babies.

The Harvard School of Public Health has done a series of studies uncovering the health benefits of coffee for preventing diabetes. In the well-known Nurses’ Health Study, they looked at 982 diabetic and 1,058 non-diabetic women without cardiovascular disease.
‘They wanted to see if the beneficial effects of coffee on metabolism were from changes in the hormone adiponectin,’ said Jonathan Galland, health writer for HuffPost Healthy Living. Adiponectin is key in that it promotes insulin sensitivity which protects individuals against Type 2 diabetes.
What they found was women who had four or more cups of coffee per day ‘had significantly higher adiponectin’ than those who did not drink coffee regularly.
Across the world, scientists in Germany, Finland and Denmark have been raving about the benefits of increasing one’s coffee intake to improve cholesterol levels and blood levels of inflammatory compounds.
Referring to the European scientists studies in the American Journal of Clinical Nutrition, ‘Coffee consumption appears to have favorable effects on some markers of sub-clinical inflammation and oxidative stress and to increase plasma concentrations of potential biomarkers of coffee intake.’
In Layman’s terms, since subclinical inflammation is a risk factor for type 2 diabetes , coffee mediates and reduces the risk of type 2 diabetes amongst people who drink coffee habitually for years.
But it’s not only caffeinated coffee that helps prevent diabetes, studies have shown that decaf may have the same positive affects also!
It’s not necessarily the caffeine that gives individuals the health benefits, Frank Hu, MD, MPH, PhD, nutrition and epidemiology professor at the Harvard School of Public Health explains to WebMD. Coffee is jam packed with other nutrients, such as antioxidants, that he says contribute to, ‘the whole package.’ Antioxidants help prevent tissue damage caused by molecules called oxygen-free radicals.
Coffee also is full of minerals (i.e. magnesium and chromium) that helps the body use the hormone insulin, which controls blood sugar (glucose). In type 2 diabetes, the body loses its ability to use insulin and regulate blood sugar effectively.
So if you’ve been looking for an excuse on which to pawn off your java addiction, now you’ve got a few health points to reference! Sip that second (or third or fourth) cup of the day and ruminate on how well you’re treating your body — and your taste buds.
So once we received our first shipment of signature Chemex filters, we decided to do a side by side brew comparison to practically determine if you could tell a difference in the cup. Watch as Allison brews up two batches on the Chemex and we taste them to find out.
Do you really need a fancy, specially-designed gadget to brew up a batch of cold coffee? Or can you just use your trusty ol’ press pot? While we carry a couple of different cold brew options (from Hario and Sowden), we wanted to see if using one of them (namely, the Sowden) produced a better, worse or similar cup to making a cold brew with a La Cafetiere french press.
So we put Allison to the test! Watch as we brew up a batch in each, using the same grind and coffee-to-water ratios, allowing them to sit over night and then giving them a taste test. We also compare how much sediment appears in the cup. So exciting!
One of the wiliest dragons to slay in the home espresso universe is milk steaming — there are basic tenets one must follow, but from there it’s just practice, practice, practice. The kind of machine you’re using will play a big part in your milk frothing success, as well as whether or not you’re working with a traditional wand vs. a panarello or a steam boiler vs. a thermoblock.
Gail walks us through tips, tricks and things to keep in mind when steaming your milk, either for the ‘wet paint’ texture for latte art or the dense, shaving cream microfoam for cappuccinos. Watch her demonstrate best practice on the Rocket Giotto and the Saeco Via Venezia.
There is nothing quite like taking a random suggestion and putting it to the test! During our original stovetop prep video, Rade mentioned using sparkling water to achieve some form of crema from the espresso and we also received a viewer suggestion that using preheated water produced a better cup.
We asked him to put these two ideas to the test to determine if either results in a noticeably improved cup. Hilarity ensued.
