Why 87–94°C Is the Only Number That Matters in Your Cup
Boiling water scorches, lukewarm water under-extracts. Here's the window printed on every Semprevivo box — and how to hit it without a thermometer.
Too hot burns the aromatics
Water straight off a rolling boil sits near 100°C and drives off the delicate top notes of ground coffee before the sugars have time to dissolve. What is left in the cup reads as bitter and flat.
Too cool leaves the cup thin
Below roughly 85°C the parts of the coffee that carry body and sweetness barely move, so the brew tastes sour and watery no matter how good the roast was.
The window printed on the box
Every Semprevivo ESC pack gives the same instruction: 150–180ml of water at 87–94°C, poured over the hanger filter. Let a boiled kettle rest for a minute or two and you are inside that window — no scale, no thermometer, no guesswork.
How to brew a drip bag, step by step
Tear the top of the bag along the dotted line. Open the hangers and hook them on the rim of your cup. Pour a little water to wet the coffee, wait a few seconds, then pour slowly in two or three rounds until you reach 150–180ml. Lift the bag out and enjoy.
Pouring outdoors
Camping or at sea, water cools fast in the wind. Pour right after the kettle settles and keep the cup sheltered so you stay inside the window.
