# Costa Rican Tarrazu Coffee (Coffea arabica) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/costa-rican-tarrazu-coffee **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-29 **Evidence Score:** 2 / 10 **Category:** Coffee Cultivars **Also Known As:** Tarrazú coffee, Tarrazu coffee, Costa Rica Tarrazú, Tarrazú Arabica, Costa Rican high-altitude coffee, Zona de los Santos coffee ## Overview Costa Rican Tarrazú coffee is a premium Coffea arabica cultivar grown in the volcanic soils of Costa Rica's Tarrazú region. This coffee contains standard caffeine levels along with fatty acids like palmitic acid (24-47 g/kg) and dietary fiber, though no specific health benefits beyond regular coffee have been clinically proven. ## Health Benefits • No clinically proven health benefits specific to Tarrazú coffee - no human trials, RCTs, or meta-analyses found • Contains fatty acids including palmitic (24-47 g/kg), linoleic, and oleic acids - compositional data only, no clinical evidence • Provides dietary fiber (55% in silverskin) and protein (19% in silverskin) - analytical data only, no health outcome studies • Contains polyphenols and chlorogenic acid - presence noted but no Tarrazú-specific [antioxidant](/ingredients/condition/antioxidant) studies available • Delivers approximately 95 mg caffeine per 250 ml cup - standard coffee content, no unique Tarrazú benefits demonstrated ## Mechanism of Action Tarrazú coffee's primary bioactive compound caffeine acts as an adenosine receptor antagonist, blocking A1 and A2A receptors in the central nervous system. The fatty acids including palmitic, linoleic, and oleic acids may influence cellular membrane composition and lipid [metabolism](/ingredients/condition/weight-management) pathways. However, these mechanisms are shared with other coffee varieties and are not unique to the Tarrazú cultivar. ## Clinical Summary No randomized controlled trials, human studies, or meta-analyses have specifically investigated Costa Rican Tarrazú coffee's health effects. Available research is limited to compositional analyses showing fatty acid content and dietary fiber levels in coffee components like silverskin (55% fiber content). Current evidence consists only of chemical characterization studies without clinical endpoints. The health effects attributed to this coffee are extrapolated from general coffee research rather than cultivar-specific investigations. ## Nutritional Profile Costa Rican Tarrazu Coffee (Coffea arabica) nutritional composition per standard 240ml brewed cup (using ~10g ground coffee): Calories: 2-5 kcal; Carbohydrates: <1g; Protein: 0.3g; Fat: <0.1g (most lipids retained in grounds). Key bioactive compounds in brewed coffee: Caffeine: 80-120mg per cup (Tarrazu beans are noted for moderate-to-high caffeine content due to high-altitude slow maturation); Chlorogenic acids (CGAs): 70-200mg per cup, predominantly 5-caffeoylquinic acid (5-CQA), 3-CQA, and 4-CQA - major polyphenol fraction, partially degraded during roasting (light roast retains more: ~350mg/cup vs dark roast ~100mg/cup); Trigonelline: 50-100mg per cup, precursor to niacin (vitamin B3) formed during roasting; Niacin (vitamin B3): 0.5-1.0mg per cup generated from trigonelline degradation during roasting. Green bean composition (per 100g dry weight): Total lipids: 12-16g (concentrated in silverskin and grounds), including palmitic acid (24-47 g/kg of lipid fraction), linoleic acid (~40% of lipid fraction), oleic acid (~10% of lipid fraction), and arachidic acid; Sucrose: 6-9g (largely degraded during roasting to form melanoidins and caramelization products); Total dietary fiber: 3-4g per 100g green bean; Silverskin fraction notably contains ~55% dietary fiber and ~19% protein (dry weight basis) - largely removed during processing and not present in brewed coffee. Minerals in brewed cup: Potassium: 100-150mg (most abundant mineral); Magnesium: 7-10mg; Phosphorus: 7mg; Manganese: 0.05mg; Trace amounts of calcium (~5mg), zinc (<0.1mg), and copper (~0.03mg). Melanoidins: 25-35mg per cup - high-molecular-weight brown polymers formed during Maillard reaction during roasting, structurally act as dietary fiber with [antioxidant](/ingredients/condition/antioxidant) properties; Diterpenes (cafestol and kahweol): present in green beans at ~5-6mg/g lipid fraction but largely filtered out in paper-filtered brewing methods (<0.1mg per filtered cup); espresso and French press retain higher levels (1-4mg per serving). Bioavailability notes: CGAs have moderate bioavailability (~30% absorbed in small intestine, remainder metabolized by colonic microbiota); caffeine bioavailability is near-complete (~99% absorbed); trigonelline has moderate absorption but limited conversion to niacin in humans; mineral bioavailability is moderate but coffee's phenolic content may reduce iron and [calcium absorption](/ingredients/condition/bone-health) when consumed with meals. Tarrazu-specific compositional distinction: high-altitude cultivation (1,200-1,900m) in volcanic soil contributes to higher sucrose content and more complex aromatic compound profile compared to lower-altitude arabica varieties, though direct comparative nutritional data between Tarrazu and other arabica origins is limited to compositional analyses without clinical validation. ## Dosage & Preparation No clinically studied dosage ranges are available for Tarrazú coffee in biomedical contexts. Typical consumption is as brewed coffee providing approximately 95 mg caffeine per 250 ml cup. No standardization specifications exist for biomedical use. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Costa Rican Tarrazú coffee contains caffeine and carries the same safety profile as other arabica coffees, with potential for [insomnia](/ingredients/condition/sleep), anxiety, and increased heart rate at high doses. Caffeine can interact with medications including warfarin, lithium, and certain antibiotics like ciprofloxacin. Pregnant women should limit caffeine intake to under 200mg daily per medical guidelines. Individuals with anxiety disorders, heart conditions, or caffeine sensitivity should exercise caution with consumption. ## Scientific Research No human clinical trials, RCTs, or meta-analyses specific to Costa Rican Tarrazú coffee were identified in the available sources. The research consists only of compositional analyses of general Coffea arabica, with no Tarrazú-specific studies containing PubMed PMIDs found. ## Historical & Cultural Context No evidence of use in traditional medicine systems was found. Tarrazú coffee is primarily recognized as a gourmet beverage valued for its flavor profiles including citrus, honey, chocolate, and vanilla notes rather than medicinal applications. ## Synergistic Combinations Not applicable - no synergistic ingredients studied ## Frequently Asked Questions ### Does Tarrazú coffee have more antioxidants than regular coffee? No clinical studies have compared antioxidant levels between Tarrazú coffee and other arabica varieties. While it contains standard coffee compounds, there's no evidence of superior antioxidant content specific to this Costa Rican cultivar. ### What makes Costa Rican Tarrazú coffee different nutritionally? Compositional analysis shows Tarrazú coffee contains palmitic acid (24-47 g/kg), linoleic and oleic acids, plus dietary fiber. However, these components are found in most coffee varieties and aren't unique to Tarrazú cultivation. ### Can Tarrazú coffee help with weight loss? No specific weight loss studies exist for Tarrazú coffee. While caffeine generally may boost metabolism, this effect applies to all caffeinated coffees and isn't enhanced in the Tarrazú variety. ### Is Tarrazú coffee safer than other coffee types? Tarrazú coffee has the same safety profile as other arabica coffees since it contains similar caffeine levels and compounds. The volcanic soil growing conditions don't create additional safety benefits or risks. ### How much caffeine is in Costa Rican Tarrazú coffee? Specific caffeine content data for Tarrazú coffee isn't published in research literature. As an arabica variety, it likely contains 95-200mg caffeine per 8oz cup, similar to other arabica coffees. ### Is Costa Rican Tarrazú coffee safe during pregnancy and breastfeeding? Costa Rican Tarrazú coffee contains caffeine (approximately 95-200 mg per 8 oz cup), which medical organizations recommend limiting to 200 mg daily during pregnancy due to potential miscarriage risk. During breastfeeding, caffeine passes into breast milk and may affect infant sleep, so moderation is advised. Pregnant and nursing individuals should consult their healthcare provider about safe consumption levels. ### Does Tarrazú coffee interact with common medications? Tarrazú coffee's caffeine content can interact with certain medications including some antidepressants, blood pressure medications, and drugs metabolized by the liver's CYP1A2 enzyme. The polyphenol compounds in coffee may also affect iron absorption and interact with medications that depend on iron uptake. Individuals taking prescription medications should consult their doctor before significantly increasing Tarrazú coffee consumption. ### What is the difference between Tarrazú coffee and other Costa Rican coffee regions? Tarrazú coffee is grown at higher elevations (1,200-2,200 meters) in the southern zone of Costa Rica, producing denser beans with more complex flavor profiles than lower-altitude varieties. The region's volcanic soil, altitude, and specific microclimates result in distinct taste characteristics—typically featuring chocolate and citrus notes—though nutritional composition remains similar to other arabica coffees. These differences are primarily sensory and related to cultivation conditions rather than substantial biochemical variations. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
