High CGA Coffee: Best Brands, Benefits, and Where To Buy
Updated - Team Colipse
CGA in coffee refers to chlorogenic acid, a polyphenol found in high concentrations in green coffee beans. A single cup of brewed coffee contains between 50–200 mg of chlorogenic acids, depending on brewing method, roast level, and coffee variety. High CGA coffee refers to coffee with the upper-range chlorogenic acid content.
High CGA coffee brands use lightly roasted beans to preserve more CGA, unlike darker roasts that degrade it during roasting. Chlorogenic acid contributes to coffee’s antioxidant, anti-inflammatory, and metabolic health benefits. When buying high CGA coffee, choose unroasted green beans or light roasts from Robusta or high-altitude Arabica varieties. Besides CGA, coffee contains other antioxidants like caffeic acid, melanoidins, trigonelline, and quinic acid.
What is Chlorogenic Acid?
Chlorogenic acid (CGA) is a dietary polyphenol found in high concentrations in green coffee beans, fruits, vegetables, and various plants. Robusta beans Coffea canephora contain 7–14% chlorogenic acids by dry weight, while Arabica beans Coffea arabica contain 3.5–7.5%, according to a 2001 study published in Food Chemistry by Chinlong Ky.
Chlorogenic acid is formed by the combination of caffeic acid and quinic acid connected by a chemical bond. The most common form of CGA is 5-O-caffeoylquinic acid. FDA classifies chlorogenic acid as Generally Recognized As Safe (GRAS).
Chlorogenic acid has limited bioavailability because it binds with plant cell wall parts like proteins, fiber, and pulp. According to Rui Hai Liu from the Department of Food Science at Cornell University, one-third is rapidly absorbed in the upper gastrointestinal tract, while the rest is metabolized by gut microbes in the colon.
Biologically, chlorogenic acid functions as an antioxidant, anti-inflammatory agent, and plant secondary metabolite. Chlorogenic acid supports cardiovascular, neuroprotective, and anti-diabetic functions by exerting anti-inflammatory, antioxidant, and metabolic regulatory effects, according to Vi Nguyen from the Department of Cell Biology and Anatomy at University of South Carolina.
How Much Chlorogenic Acid is in a Cup of Coffee?
A 3.4 oz (100 ml) cup of brewed coffee contains between 50–200 mg of chlorogenic acids, depending on brewing method, roast level, and coffee variety, according to a 2019 review published in Beverages by Adriana Farah. The research provides a broad survey of studies reporting chlorogenic acids in coffee beverages. The study reports espresso coffee contains the highest chlorogenic acid content, up to 1000 mg/100 ml, due to pressure extraction and high coffee-to-water ratios. Filtered and drip coffee have the lowest, ranging from 25–150 mg/100 ml depending on roast.
The amount of chlorogenic acid in a cup of coffee was also reported in a 2014 study titled "Variations in caffeine and chlorogenic acid contents of coffees" by Izáar A. Ludwig et al. measuring 104 espresso, cappuccino, and instant coffee samples. The study examined variation in CQA levels across beans, roast levels, and brewing methods. Chlorogenic acid content per serving ranged from 6 mg to 188 mg. The study showed that lighter roasts, gentler brewing, and larger servings each increase total CGA in coffee.
What is High CGA Coffee?
High CGA coffee refers informally to coffee with the upper-range chlorogenic acid content. High CGA coffee is a growing trend driven by health-conscious consumers. Chlorogenic acid in coffee helps to improve metabolic and cardiovascular health by reducing visceral fat, lowering blood glucose, and decreasing inflammation.
High CGA coffee improves metabolic markers when consumed daily, according to a 2025 study by Katarzyna Zalewska at Poznan University of Medical Sciences. The study showed that over 12 weeks, drinking coffee enhanced with 369 mg of CGA per day reduced belly fat, total body fat, and visibly decreased waist size and weight compared to low-CGA coffee.
Not all coffees are high in chlorogenic acid. CGA levels in coffee vary by bean type, roast level, and brewing method. Light roasts generally retain more CGA than dark roasts. Robusta beans typically contain more CGA than Arabica. High temeperature and longer roasting reduces CGA content significantly.
What are the Best High CGA Coffee Brands?
The best high-CGA coffee brands are defined by bean origin, roast level, and post-harvest processing. Top options use Robusta or high-altitude Arabica beans, apply light roasting to preserve CGAs, and control processing methods to retain antioxidant levels. Below are five brands known for consistently high chlorogenic acid content.

What are the Benefits of Chlorogenic Acid in Coffee?
Benefits of chlorogenic acid in coffee include lowering blood pressure, providing antioxidant protection, and supporting weight loss in humans.
- Chlorogenic acid in coffee lowers blood pressure: A 2025 study published in Nutrients confirms that chlorogenic acid in coffee lowers blood pressure by inhibiting the renin–angiotensin–aldosterone system (RAAS), improving endothelial function, increasing nitric oxide production, and reducing oxidative stress. These effects were especially evident in individuals with mild hypertension.
- Glucose regulation improves with chlorogenic acid found in coffee: A 2020 meta-analysis published in the Journal of Diabetes and Metabolic Disorders by Mehrnaz Morvaridi found that green coffee extract high in chlorogenic acid reduced fasting blood sugar in adults. The researchers concluded that CGA improves glucose control by enhancing insulin sensitivity, inhibiting glucose absorption, and stimulating glucose uptake.
- CGA in coffee provides antioxidant protection: A 2022 study published in Molecules by Alexis Rojas-González confirms that chlorogenic acids in coffee provide antioxidant effects by scavenging free radicals, chelating metal ions, and preventing oxidative damage to LDL and DNA. These effects are primarily attributed to 5-CQA, the most abundant CGA in green coffee beans.
- Chlorogenic acid supports weight loss: A 2022 study titled "Chlorogenic acid in green bean coffee on body weight" found that chlorogenic acid in green bean coffee extract (GBCE) supports weight loss. The meta-analysis showed that taking 500 mg/day of CGA reduced weight by 1.3 kg.
What are the Side Effects of Chlorogenic Acids in Coffee?
The most common side effects of chlorogenic acids in coffee are minimal. A 2024 study titled "Chlorogenic Acid: A Systematic Review on the Biological Functions, Mechanistic Actions, and Therapeutic Potentials" published in Nutrients shows CGA is generally well-tolerated with no significant toxicity. However, high CGA doses at 2 g/day for 7 days may moderately increase plasma homocysteine levels by 11–12% in humans. This is equivalent to roughly 4–10 cups of brewed coffee. No adverse effects were noted in animal studies even at high doses.
What Coffee Has the Highest Chlorogenic Acid?
Unroasted green coffee beans have the highest chlorogenic acid content, with levels up to 14.4% by weight, according to a 2019 study by Sabur Badmos published in Food Research International. Robusta coffee beans also rank highest in chlorogenic acid content, typically ranging from 7.0% to 14.4% of dry weight.
Once roasted, coffee retains the most chlorogenic acid in light roasts, not dark roasts. A 2016 study "Chlorogenic acids, caffeine content and antioxidant properties of green coffee extracts" by Jeszka-Skowron identified green beans, light roasts, Robusta, high-altitude Arabicas, and espresso-style brews as having the highest CGA levels. The study identified dark or Italian roasts, heavily roasted Arabica, and steamed coffees as having the lowest CGA levels.
The amount of CGA in coffee depends on where it comes from. Altitude, soil, and climate affect how much chlorogenic acid a coffee plant makes. For example, a 2006 study by Adriana Farah titled "Phenolic compounds in coffee" showed that Brazilian Conillon and African wild Robusta had the highest CGA levels, reaching 11.3% of dry matter. Wild Ethiopian arabica varieties from East Africa had the lowest CGA, as low as 1.2%.
The following table, sourced from a 2006 study "Phenolic compounds in coffee," summarizes the total chlorogenic acid content across various coffee species and cultivars.
| Sample | Total CGA per 100 g green coffee |
|---|---|
| C. arabica | 6.88 |
| C. arabica var Caturra | 5.62 |
| C. arabica var Bourbon | 5.67 |
| Wild C. arabica (average) | 4.10 |
| C. arabica (Angola) | 6.10 |
| C. arabica (Angola) | 5.65 |
| C. arabica (Angola) | 7.85 |
| C. arabica var Bourbon (Brazil) | 5.25 |
| C. arabica cv. Longberry (Ethiopia) | 5.73 |

What Other Antioxidants are in Coffee Beside Chlorogenic Acid?
Other antioxidants in coffee besides chlorogenic acid include caffeic acid, melanoidins, trigonelline, and quinic acid. These compounds help neutralize free radicals and contribute to coffee’s health benefits. The roasting process alters their levels but preserves significant antioxidant capacity.
Does Decaf Coffee Still Contain Chlorogenic Acid?
Yes, decaf coffee still contains chlorogenic acid, often retaining over 90% of the antioxidants found in regular coffee. Some studies show that the decaffeination process can increase CGA levels by 5.5–18%, highlighting the strong relationship between decaf and polyphenols, and making decaf a rich source of antioxidants with similar or slightly enhanced benefits compared to regular coffee.
