Drinks-knowledge quiz
Coffee — beans to cup.
Espresso, filter, grind size, why your coffee tastes bitter — a pop quiz on what's actually going on in the cup.
Coffee is one of those things almost everyone drinks and almost no-one is fully sure how it works. What does 'extraction' really mean? Why does the same coffee taste sour one morning and bitter the next? What's a flat white versus a latte versus a cortado, and is anyone still actually drinking a macchiato? Quizine's coffee questions cover beans, roasts, grind size, the basic brew methods, espresso ratios, and the small things — water temperature, freshness, grind consistency — that make most of the difference. Short explanations, no judgement.
Three sample questions
Have a think, then tap to reveal the answer. The real quiz adapts in difficulty as you go.
-
Which of these drinks is made by forcing pressurised hot water through finely-ground coffee?
Reveal answer
B. Espresso
Espresso is defined by the method, not the bean — about 9 bars of pressure pushing water through a finely-ground, tamped puck for roughly 25–30 seconds. The result is a small, concentrated shot with a layer of crema on top.
-
For a typical pour-over, what coffee-to-water ratio (by weight) is the most common starting point?
Reveal answer
C. 1:16
Around 1:16 — for example 20 g of coffee to 320 g of water — is the widely taught pour-over baseline. Stronger ratios like 1:14 push intensity; weaker ones like 1:18 lean tea-like. Espresso is a different game entirely, sitting around 1:2.
-
In specialty-coffee brewing, 'extraction yield' usually refers to:
Reveal answer
B. The percentage of the dry coffee's mass that has dissolved into the brew
Extraction yield is the share of the ground coffee's mass that ends up dissolved in the cup, typically 18–22% for a balanced brew. Below ~18% tastes sour and underdeveloped; above ~22% tastes bitter and astringent. Total Dissolved Solids (TDS) is the related strength measurement.
Questions, asked
Is Quizine free?
Completely. No account, no card, no upsell. Sign in if you'd like your progress to follow you between phone and laptop; otherwise it all works in the browser, no questions asked.
Do I need a fancy espresso machine to find this interesting?
No. A lot of the questions are about brewing principles that apply equally to a moka pot, an aeropress, or a filter cone. The kit you happen to use is almost beside the point.
How do the levels work?
Three levels of difficulty. You start at level one and the quiz nudges you up after a short run of correct answers; a couple of wrong ones drops you back down. The aim is to keep you on questions that are just hard enough to be interesting.
How long does a session take?
Five minutes is normal. Most people answer eight to twelve questions and come back the next day. The daily challenge is three questions on purpose — easy to keep up with.
