At BodyBrew we are extremely health conscious coffee lovers and started cold brewing way back in 2005 when it wasn't as popular as it is today.
Shortly after we built our first cold brew system in 2009 we uncovered some research studies from Harvard and Baylor Universities that indicated Espresso and French Press had very high levels Cafestol, (a cholesterol elevating compound). This prompted us to question how the cold brew method compared to other brew methods. We conducted our first lab tests in 2009, and again in 2017 where we partnered with a lab that specializes in coffee testing and coffee research. See lab test results below.
Published research from Baylor College of Medicine and Harvard University shows that Cafestol could be harmful to your health. According to Dr. David Moore, Professor of Molecular and Cellular Biology at Baylor College of Medicine, Cafestol is the most potent cholesterol elevating compound known. Dr. Marie-Louise Ricketts, a postdoctoral student and first author of the report, French press coffee and espresso contain the highest levels of Cafestol.
According to a study published by Molecular Endocrinology in July 2007, CAFESTOL if the most potent cholesterol elevating compound found in the human diet, and consumption of unfiltered coffee such as the Scandinavian-type boiled, (French-press), and Turkish coffee raises triacylglycerol and low-density lipoprotein (LDL)-cholesterol concentrations in humans. A high intake of boiled coffee was associated with hypercholesterolemia and risk of coronary heart disease in Norway and Finland, and CAFESTOL was later identified as the factor responsible. https://academic.oup.com/mend/article/21/7/1603/2738489

Acids in coffee are often responsible for stomach upset and can even lead to heartburn and aggravate acid reflux. According to the Cleveland Clinic, 1 out of every 10 adults experiences heartburn one or more times per week. Such frequency can indicate GERD. According to healthline.com cold brew coffee has a lower amounts of acids, which may make it an acceptable choice for those with GERD or heartburn. However, not all cold brew is created equal. For example cold brewing using a French press shows 31% more Titratable (an approximation of the Total Acidity of a solution) acids than our cold extraction method.

Studies at the Texas A&M Health Sciences Center, Baylor College of Dentistry as well as the President of the Academy of General Dentistry, say tannic acid in coffee can stain teeth and weaken tooth enamel. Your enamel is what protects your teeth, so if it is weakened or wears away, then your teeth become more vulnerable to decay.
Tooth enamel is the hardest substance in your body, it’s not smooth and flat like it appears. Instead, it has tiny pits and grooves that get filled with beverage and food particles. If you drink hot coffee, the heat can make your teeth expand and contract which allows the stains to penetrate even farther into the pits and grooves in the enamel. Tannic acid can also wear teeth down, and promote tooth decay, making cavities more likely.
Third party lab tests show coffee brewed using the BOD Cold Brew Coffee System is low in Tannic acid. As you can see from the graph below not all cold brew is created equal either. Brewing in a French press produces coffee with over 68% more tannic acid than our cold brew/cold extraction method, and brewing in a Espresso machine produces coffee with 858% 8X more tannic acid than our cold brew/cold extraction method.
