Top Herbal Tea Flavors: Celestial Seasonings and Yogi

Celestial Bengal Spice (a herbal blend) contains 0 mg of caffeine per 240 ml cup (herbal tea, caffeine-free).

• 0 mg — Celestial Bengal Spice and most Celestial/Yogi herbal-only blends are caffeine-free per 240 ml cup.
• 47 mg — A 240 ml cup of black tea typically contains ~47 mg of caffeine (use this to compare strength).
• 70 mg — Matcha (1 tsp, 240 ml) is a concentrated tea with ~70 mg caffeine per serving.
• 96 mg — Standard 240 ml drip coffee contains ~96 mg; use this value for decay math and sleep timing examples.
• 400 mg/day — FDA's recommended upper limit for healthy adults; aim lower in pregnancy (~200 mg/day) and for adolescents the AAP discourages regular caffeine use.

Why Bengal Spice is caffeine-free and what that means

Celestial Bengal Spice is formulated as an herbal, spice-forward tisane rather than a Camellia sinensis infusion. That means its base is dried spices and herbs — not black or green tea — so caffeine is effectively zero for a standard 240 ml steep (dataset value: 0 mg). The lack of caffeine makes Bengal Spice a late-evening choice when you want warming aromatics without alertness.

Flavor groups: Celestial Seasonings fruit zingers

Fruit Zinger-style blends center hibiscus, orange peel and apple for bright, tart-sweet cups. Celestial Seasonings' fruit lineup emphasizes lively acidity and aroma rather than tannic bitterness — these are naturally caffeine-free when they contain only fruit and herbs. Steep 5–7 minutes for full flavor; cool quickly for iced variations.

Spice and comfort blends: Bengal Spice and kin

Bengal Spice and similar blends layer cinnamon, cardamom, cloves and ginger. The result is chai-like warmth without tea-caffeine. These blends are designed for aroma and digestive comfort; they can be mixed with milk or a plant milk for a caffeine-free 'chai' experience. If a blend includes black tea, expect caffeine near black tea levels (≈47 mg per 240 ml).

Herbal wellness teas (Yogi examples) and what to expect

Yogi markets many functional herbal blends — Turmeric Ginger, Honey Lavender, and so on — that are typically caffeine-free when made from herbs and roots. Yogi also produces blends containing black or green tea: those will carry caffeine roughly in the range of green tea (~28 mg/240 ml) to black tea (~47–50 mg/240 ml). Check packaging and use the USDA FoodData Central or product label for exact numbers.

Comparing Celestial Seasonings and Yogi: flavor, caffeine, and use cases

Both brands offer large herbal portfolios. Practical differences:

• Focus: Celestial leans fruit- and spice-forward bagged blends; Yogi emphasizes 'functional' blends with Ayurvedic-inspired herbs.
• Caffeine: Herbal-specific offerings from both are 0 mg per 240 ml. If a blend contains black/green tea, use black tea (≈47 mg) or green tea (≈28 mg) as benchmarks.
• Preparation: Both perform well as steeped hot tea, iced, or in milk-based preparations; stronger steeps extract more flavor but not caffeine from true herbals.

How brewing, format and ingredients affect caffeine

For true herbals, steep time and temperature affect flavor and extraction of volatile oils, not caffeine. For blends that include Camellia sinensis leaves, caffeine per 240 ml depends on leaf type and method: dataset comparisons show drip coffee 96 mg/240 ml, pour-over 145 mg/240 ml, French press 107 mg/240 ml, and black tea ~47 mg/240 ml. Processing (instant, cold brew) and concentration create larger spreads — cold brew can reach 200 mg per 240 ml in concentrated servings.

Drink / blend	Serving	Caffeine (mg)
Celestial Bengal Spice (herbal)	240 ml	0 mg
Yogi Turmeric Ginger (herbal)	240 ml	0 mg
Black tea	240 ml	47 mg
Green tea	240 ml	28 mg
Matcha (1 tsp)	240 ml	70 mg
Drip coffee	240 ml	96 mg
Cold brew	240 ml	200 mg
Red Bull (250 ml)	250 ml	80 mg

Timing, half-life and sleep: concrete decay math

Caffeine follows first-order kinetics with a population-average half-life of ~5.7 hours (sources: FDA, Mayo Clinic summaries). That means roughly 69% remains after 3 h, 48% after 6 h, 33% after 9 h and 23% after 12 h. Use the table below to estimate how much caffeine remains from a 96 mg drip coffee.

Time after dose	% remaining (approx)	Remaining from 96 mg (mg)
3 hours	~69%	~66.2 mg
6 hours	~48%	~46.1 mg
9 hours	~33%	~31.7 mg
12 hours	~23%	~22.1 mg

Practical takeaway: a 96 mg morning cup leaves measurable caffeine in the bloodstream well into the afternoon and early evening for many people. For sensitive sleepers, avoid caffeine within 6–8 hours of bedtime.

Health, safety and tracking

Agency guidance: the FDA cites 400 mg/day as a reasonable upper limit for healthy adults; pregnant people are commonly advised to limit intake to ~200 mg/day (varies by guideline). The American Academy of Pediatrics discourages caffeine for young adolescents because of sleep and developmental concerns. Herbal blends like Bengal Spice let you enjoy warming flavors without counting toward these limits.

If you track multiple sources (tea, coffee, energy drinks, pills), a tracker like CoffeeLog helps total daily intake and timing so you can correlate caffeine with sleep and symptoms. For medical questions about pregnancy, anxiety, heart conditions or suspected overdose, consult a clinician immediately — this page is informational, not medical advice.
