Fellow Stagg EKG vs Ember Smart Mug 2: Precision Brewing vs Temperature Holding
The Stagg EKG boils water to the exact degree for pour-over coffee. The Ember Mug keeps brewed coffee at that exact drinking temperature for 2 hours at your desk.
Real-World Kitchen Testing
These two devices tackle coffee temperature control from opposite ends of the brewing journey: The Fellow Stagg EKG is the indispensable tool for extracting great coffee. If you brew light-roast specialty coffee with a V60 or Chemex, pouring boiling 212°F water scorches the grounds and extracts harsh tannins. The Stagg lets you dial in exactly 201°F, and its counterbalanced gooseneck spout pours a thin, restricted ribbon of water that won’t disrupt the coffee bed. The Ember Smart Mug 2 takes over once the coffee is brewed. If you are a slow drinker who gets distracted by Slack messages or meetings, standard ceramic mugs leave you with cold, sour coffee in 15 minutes. The Ember maintains your preferred drinking heat (135°F is the sweet spot) for two hours. While the Ember is a wonderful luxury, the Stagg EKG is the fundamental tool that makes great coffee possible in the first place.
