# Tarrazu Peaberry (Coffea arabica) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/tarrazu-peaberry **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-24 **Evidence Score:** 2 / 10 **Category:** Coffee Cultivars **Also Known As:** Coffea arabica var. Tarrazu, Costa Rican Peaberry, Tarrazu Single Bean, Volcanic Peaberry Coffee, Central American Round Bean, Tarrazu Caracolillo ## Overview Tarrazu Peaberry is a premium variant of Coffea arabica grown in Costa Rica's Tarrazú region, containing 0.8-1.4% caffeine and 3-5% chlorogenic acids. These compounds provide adenosine receptor antagonism for alertness and [antioxidant activity](/ingredients/condition/antioxidant), though specific research on this cultivar variant is lacking. ## Health Benefits • No specific health benefits documented for Tarrazu Peaberry variant (no clinical trials found) • General C. arabica coffee contains caffeine (0.8-1.4% dry weight) for potential alertness enhancement (evidence quality: not studied for this variant) • Contains chlorogenic acids (3-5%) with theoretical [antioxidant](/ingredients/condition/antioxidant) properties (evidence quality: not studied for this variant) • May share general coffee's [glucose metabolism](/ingredients/condition/weight-management) effects via AMPK pathway (evidence quality: not studied for this variant) • Potential [cardiovascular](/ingredients/condition/heart-health) effects common to C. arabica consumption (evidence quality: not studied for this variant) ## Mechanism of Action Caffeine in Tarrazu Peaberry acts as an adenosine receptor (A1 and A2A) antagonist, blocking drowsiness signals and promoting alertness. Chlorogenic acids inhibit glucose-6-phosphatase and provide antioxidant activity through [free radical scaveng](/ingredients/condition/antioxidant)ing. The peaberry processing may concentrate these bioactive compounds compared to regular beans. ## Clinical Summary No clinical trials have specifically studied Tarrazu Peaberry variant health effects. General arabica coffee research shows caffeine doses of 40-300mg improve [cognitive performance](/ingredients/condition/cognitive) and alertness in multiple randomized controlled trials with sample sizes ranging from 20-200 participants. Chlorogenic acid studies suggest 140-400mg daily may support [glucose metabolism](/ingredients/condition/weight-management), but these findings cannot be directly applied to this specific cultivar. ## Nutritional Profile Tarrazu Peaberry (Coffea arabica) — nutritional data extrapolated from C. arabica green and roasted bean composition, as peaberry-specific analytical studies are absent. Per 100g roasted ground coffee: Calories ~0 kcal (as brewed beverage per 240ml serving ~2 kcal). Macronutrients in dry roasted bean: Protein 10-13g/100g (predominantly non-digestible due to roasting Maillard reactions); Carbohydrates 28-32g/100g (mostly non-fermentable polysaccharides; negligible glycemic impact in brewed form); Lipids 15-17g/100g (diterpenes cafestol and kahweol ~4-5mg per unfiltered cup; largely retained in filter paper when paper-filtered). Bioactive compounds: Caffeine 1.1-1.4% dry weight in green bean, reducing to approximately 0.8-1.2% post-roast (brewed cup ~80-120mg per 240ml); Chlorogenic acids (CGA) 6-9% in green bean, degrading significantly to 1-4% post-roast (predominant isomers: 5-caffeoylquinic acid, 3-caffeoylquinic acid); Trigonelline 0.6-1.0% green bean (partially converts to niacin/vitamin B3 during roasting, yielding ~0.5-1.0mg niacin per cup); N-methylpyridinium (NMP) formed during roasting ~0.1-0.3mg/cup. Minerals per 240ml brewed cup: Potassium 116mg, Magnesium 7mg, Manganese 0.1mg, Niacin (B3) ~0.5mg. Peaberry morphology (single oval bean vs. flat-sided pair) is theorized to produce more uniform roasting and potentially higher concentration of volatiles and soluble solids per bean mass, though quantified compositional differences versus flat-bean Tarrazu C. arabica are not documented in peer-reviewed literature. Bioavailability note: CGAs show 30-72% absorption in humans; caffeine nearly 100% bioavailable orally; cafestol/kahweol bioavailability depends heavily on brewing method (espresso ~4mg/cup, paper-filtered ~0.2mg/cup). ## Dosage & Preparation No clinically studied dosage ranges exist for Tarrazu Peaberry in extract, powder, or standardized forms, as it lacks biomedical trials. Typical culinary consumption of C. arabica coffee is 1-3 cups (200-600 mg caffeine) daily, but no standardization (e.g., to chlorogenic acid) is documented for this variant. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Tarrazu Peaberry contains caffeine which can cause anxiety, [insomnia](/ingredients/condition/sleep), and increased heart rate at doses above 400mg daily. Caffeine interacts with adenosine medications, certain antibiotics (ciprofloxacin), and may reduce iron absorption when consumed with meals. Pregnant women should limit caffeine intake to under 200mg daily, and individuals with anxiety disorders should use caution. ## Scientific Research No clinical trials, RCTs, or meta-analyses specific to Tarrazu Peaberry were identified in the search results or known PubMed records. While general coffee (C. arabica) studies exist (e.g., on chlorogenic acids for metabolic effects, PMID: 29952266), none distinguish this cultivar variant by region or peaberry form, precluding specific evidence. ## Historical & Cultural Context Tarrazu Peaberry has no recorded historical use in traditional medicine systems. C. arabica originated in Ethiopia and spread globally from the 15th century for beverage use, not medicinal applications; Tarrazu cultivation began in the 18th-19th centuries primarily for export as a commodity crop. ## Synergistic Combinations Green tea extract, L-theanine, rhodiola rosea, guarana, yerba mate ## Frequently Asked Questions ### What makes Tarrazu Peaberry different from regular coffee beans? Peaberry beans are single seeds that develop when only one seed forms in the coffee cherry instead of two. This may result in more concentrated flavor compounds and potentially higher levels of caffeine and chlorogenic acids per bean. ### How much caffeine is in Tarrazu Peaberry coffee? Tarrazu Peaberry contains approximately 0.8-1.4% caffeine by dry weight, similar to other arabica varieties. A typical 8-ounce cup would provide roughly 80-120mg of caffeine depending on brewing method and bean concentration. ### What are the antioxidants in Tarrazu Peaberry? The primary antioxidants are chlorogenic acids, comprising 3-5% of the bean's dry weight. These phenolic compounds include 3-caffeoylquinic acid and 5-caffeoylquinic acid, which provide free radical scavenging activity. ### Is Tarrazu Peaberry safe for daily consumption? Yes, when consumed in moderation (under 400mg caffeine daily for healthy adults). This translates to approximately 3-4 cups of coffee, though individual tolerance varies based on body weight and caffeine sensitivity. ### Does Tarrazu Peaberry have any proven health benefits? No specific health benefits have been clinically proven for this particular cultivar variant. While general arabica coffee research suggests potential cognitive and metabolic benefits, these findings cannot be directly applied to Tarrazu Peaberry without specific studies. ### Is Tarrazu Peaberry safe during pregnancy and breastfeeding? Tarrazu Peaberry contains caffeine (0.8-1.4%), and most medical guidelines recommend limiting caffeine intake during pregnancy to below 200mg daily due to potential risks. Women who are breastfeeding should also moderate caffeine consumption as it passes into breast milk. Consult with a healthcare provider before consuming Tarrazu Peaberry regularly during pregnancy or lactation. ### Does Tarrazu Peaberry interact with common medications? Tarrazu Peaberry's caffeine content may interact with certain medications including stimulants, some antidepressants, bisphosphonates for bone health, and medications for anxiety or sleep disorders. Caffeine can also affect the absorption of some iron supplements and increase the effects of stimulant medications. If you take prescription medications regularly, consult your pharmacist or doctor before making Tarrazu Peaberry a daily habit. ### How does Tarrazu Peaberry compare to other single-origin coffee variants for supplemental use? Tarrazu Peaberry is a specific morphological variant from Costa Rica's Tarrazu region, not typically used as a supplement ingredient—it is consumed primarily as a beverage coffee. Other coffee origins may have different chlorogenic acid concentrations and flavor profiles, but no clinical evidence distinguishes Tarrazu Peaberry's nutritional profile from other arabica variants. For supplemental purposes, standardized coffee extract products provide more consistent dosing than whole bean variants. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
