Best for
  • • Coffee drinkers who want a mushroom coffee that still tastes like coffee
  • • Drip, pour-over and French press brewers
  • • Fans of dark, low-acid roasts
  • • People who want disclosed, substantial mushroom doses
  • • Flavoured instant drinks that double as a latte or iced coffee
  • • Shoppers already familiar with UK functional brands
Strengths
  • Tastes like regular dark-roast coffee, and most reviewers detect no mushroom flavor
  • Works in drip, pour-over, French press or cold brew
  • USDA Organic coffee from a family-run Honduran co-op
  • Publishes per-ingredient doses (1,000 mg each of lion's mane, cordyceps and chaga)
  • Fruiting-body extracts and KSM-66 ashwagandha
  • Several flavours; mixes hot or iced with water or milk
Watch-outs
  • Full caffeine (about 150 mg per 12 oz), so it won't help anyone cutting back
  • Per-serving lion's mane and chaga amounts aren't disclosed
  • Expensive in the US ($67 per 30-serving bag) plus international shipping
  • Caffeine varies (80–120 mg), which may surprise people looking for a low-caffeine drink
