Why the Last Glass Poured From a Pan Tastes Strongest

A pot poured into four glasses rarely produces four identical drinks. The last glass is usually darker and stronger, and the reason is what happens in the pan while you pour.

Solids settle while the pan sits

Fine spice particles, leaf fragments and milk solids are denser than the liquid around them and drift downwards as soon as the boil stops agitating the pan.

By the time the second or third glass is being filled, the liquid near the base carries a noticeably higher load of that material than the liquid poured first.

Anything small enough to pass the strainer therefore arrives disproportionately in the final glasses, taking its colour and astringency with it.

The strainer contribution grows

Leaf and spice sitting in the strainer keep releasing into whatever passes through them, and the last liquid through has the most saturated bed to travel past.

Cooks also tend to press or tap the strainer at the end to recover the retained liquid, and that liquid is the most tannic in the pot.

Both effects push in the same direction, so the final glass gets extra strength from two independent sources.

Fat rises while solids sink

Milk fat moves the other way, gathering at the surface, so the first pour takes a richer, creamier share and the last takes a leaner one.

That is why the final glass can taste both stronger and thinner at the same time, which sounds contradictory but follows directly from the separation.

Any skin that has formed compounds it, since it sits on top and either goes into the first glass or is lifted off before pouring.

Reducing the spread

Stirring the pan immediately before each pour redistributes both the settled solids and the risen fat, and costs nothing.

Pouring in two passes, half into each glass and then topping up in reverse order, evens the distribution without requiring any measurement.

Straining the whole pot into a jug first and pouring from the jug is the most reliable method, since one vessel is mixed once and dispensed evenly.

Who gets which glass is a household question

Because the difference is real and consistent, households where one person prefers a stronger cup can simply pour theirs last rather than making two pots.

Stalls exploit the same effect in reverse, keeping the pan moving constantly so that every glass sold is comparable regardless of when in the pot's life it was poured.

Either approach is fine. What causes complaints is the difference existing without anyone knowing it is there.
