New research identifies three main groups of caffeine sensitivity among individuals.
Genetic differences help explain why everyone experiences coffee’s effects differently.

Coffee drinkers fall into one of three major groups based on their caffeine sensitivity, according to physician and author Dr J.W. Langer, in a new report authored for the Institute for Scientific Information on Coffee (ISIC).
The report, “Genetics, Metabolism and Individual Responses to Caffeine,” draws on existing research to explain how the body metabolizes caffeine, why some people are more affected by caffeine than others, and how healthcare professionals can take this into account when advising patients.

Planning a meeting? Serving coffee can focus group discussion, boost involvement and leave members feeling better about their own and others’ participation.
Those are the findings of new research on the effects of caffeine on group performance from the Graduate School of Management at the University of California, Davis.
Decades of coffee research have explored its effects on the individual, but this study is the first on the effects on performance in group tasks.
The NCA Cold Brew Toolkit draft will be open for coffee industry comment through the end of May
An edited version of the following article was originally published in the May 2018 issue of Tea & Coffee Trade Journal
Cold brew has taken off – and it’s changing the way we drink coffee.
Total retail sales of refrigerated cold brew grew by about 460 percent from 2015 to 2017, reaching an estimated $38.1 million in sales this year, according to research from Mintel.
And, unlike avocado lattes, cold brew is more than a passing trend. About 10% of coffee drinkers reported having cold brew daily in 2017, according to the NCA National Coffee Drinking Trends report – up from only 1% in 2015. Experts predict that this category will continue to drive coffee market growth.
But despite of – or perhaps due to – this sudden popularity, there are still a lot of questions and misconceptions around cold brew. This is especially true for coffee companies that are considering making, serving, or selling cold brew.

What do you need to do to brew better filter coffee? That’s one of the many questions UC Davis Coffee Center is setting out to answer, through a variety of research projects. After all, there’s nothing like hard science for an answer you can trust.
Professor William Ristenpart, the center’s Director, agreed to talk me through his current work and what we can expect to see in the future, from the impact of coffee filter baskets to water quality and temperature.
It’s more complicated than you may think.
Caffeine has been consistently shown to improve athletic performance, and its consumption has been subjected to ongoing scrutiny for elite athletes.
Today, Olympic athletes are permitted to enjoy a cup of coffee before competing. But between 1984-2004, the World Anti-Doping Agency (WADA) banned high concentrations of caffeine from all Olympic events.

When it comes to sustainability in the coffee supply chain, industry members have been finding creative ways to conserve on every level, from the farm to the coffee shop. But what happens to the grounds after the coffee’s brewed?
Many coffee shops already have composting programs, but what if there were a way, not only to divert used grounds from the landfill, but to use those grounds to produce energy? Research at the National Renewable Energy Laboratory (NREL) is exploring this question — and is starting to see some exciting developments with help from the coffee industry.

One of today’s challenges isn’t finding enough information on a particular subject, but rather deciding how to evaluate all the information that’s available. Is that information unbiased, expert, and useful?
This is true not only for coffee drinkers, but also for consumers seeking information about the impact of coffee on their health. Sorting through the headlines, opinions, blog posts, and advice columns isn’t easy, which is why it is always best to seek out any underlying research on a topic. (For insight into evaluating coffee-and-health research, see “Behind the Headlines: Coffee, Health, and Research.”)
We were reminded of this after an NCA member recently asked, “Does coffee contain gluten?”

Science shows coffee can have major health perks at any temperature.
Summer’s hottest drink is also a healthy way to beat the heat.
Cold brew coffee — made by steeping coffee grounds in cold water overnight or longer — is just as healthy as regular coffee, according to Frank Hu, Ph.D., chair of the Department of Nutrition at Harvard T.H. Chan School of Public Health, in a recent Health.com article.
“Caffeine improves athletic performance. This is a truth almost universally acknowledged in exercise science.” — Gretchen Reynolds, The New York Times
Drinking caffeinated coffee has been scientifically linked to improved physical performance. And for years, many scientists, coaches, and athletes believed that an athlete had to abstain for days or weeks before an event to gain a boost.
But a new study published in the Journal of Applied Physiology suggests that these ideas about caffeine and athletic performance are outdated.

Sometimes facts are so obvious they become invisible.
In the case of coffee, one of those facts is this: Coffee comes from a plant. The entire $225 billion dollar coffee industry in the U.S. is built up from the roots of billions of living, breathing coffee plants that spend their days turning sunlight into fruit. Once you stop and think about it, it’s kind of profound. Nearly 1.7 million jobs — including, if you are reading this, probably yours — depend on those plants doing their thing, photosynthesizing, outsmarting diseases and pests, being rained on at the right time in the right amounts.
It’s also profound to think about just how fragile the entire arrangement is. The vast majority of coffee plants in the field today are really, really (really) genetically similar. Most varieties are not resistant to major diseases. Most are way too old (World Coffee Research guesses that about 50% of coffee trees are more than 50 years old). That leaves coffee especially vulnerable — to disease epidemics like the one that devastated Central American production after 2012, to extremes in weather like excessive rain or drought or frost.
When crops are facing challenges like these, it helps to go back to basics: Coffee is a plant. So — what is needed to help the plant thrive? And, thereby, to help the humans who depend on it?
