How much caffeine is in Lion's Mane Iced Cold Brew?

Each 12 oz (355ml) served over ice serving contains approximately 150 mg of caffeine. For comparison, a standard 8 oz cup of brewed drip coffee contains around 95 mg. Actual content varies with dose, water temperature, and contact time.

What temperature should I use for Lion's Mane Iced Cold Brew?

Target 20°C (68°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Lion's Mane Iced Cold Brew be extracted?

Extract for 16-18 hours using Cold Brew Immersion, at a ratio of 1:8 concentrate (100g coffee to 800g water), prepared at Coarse / Kosher Salt. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Lion's Mane Iced Cold Brew taste bitter?

Bitterness almost always indicates over-extraction. Shorten the contact time, lower the water temperature slightly, or grind coarser. Change one variable at a time so you can tell which one was responsible.

Who should avoid Lion's Mane Iced Cold Brew?

Lion's Mane is a mushroom. Anyone with a mushroom or mould allergy should avoid it, and reactions including skin and respiratory symptoms have been reported. Evidence in pregnancy and breastfeeding is absent rather than reassuring. Avoid unless a clinician advises otherwise. Interactions are poorly characterised. Discuss with a pharmacist if you take anticoagulants, diabetes medication, or immunosuppressants.

Where it sits

Stronger than 340 of the 345 other drinks in the catalogue, and weaker than 3.

That is 150 mg in a 12 oz (355ml) served over ice serving — a concentration of 42.3 mg per 100 ml. The scale above ranks whole servings, and servings differ in size, so a larger drink can sit further right while being weaker cup for cup.
