How to tell when berries are actually ripe

Start with the fact that governs all of it: no berry ripens after picking. Strawberries, blueberries, raspberries, boysenberries, blackberries and cherries are all exactly as sweet when you eat them as they were when you took them off the plant. There is no bench-ripening to fall back on, so being fussy in the row is the whole game.

The test for each

Strawberries. Red all the way to the shoulder, under the green cap. A white or pale ring at the top means it was picked early and it will stay sour. Pinch the stem rather than pulling the berry, which tears it.

Blueberries. Look at the point where the berry meets the stem. Any red or green there and it is not ready, however blue the rest looks. A ripe berry is dusty blue to the stem scar and rolls off under your thumb without a pull.

Raspberries. The definitive one: a ripe raspberry slides off its core and comes away hollow. If the white core comes with it, it was not ready.

Boysenberries. Deep purple-black and dull rather than glossy, with a slight give. Shiny and firm means unripe, and an unripe boysenberry is sharply acidic in a way the ripe fruit never is.

Blackberries. Black all over with no red at the tip, gone dull rather than shiny, and unlike a raspberry it keeps its core.

Tayberries. Deep red and soft. They are ripe when they look almost too far gone, and they are the most fragile thing on this list.

Haskaps. The one that has to be opened. The skin colours deep blue well before the fruit is ready, so cut one: ripe haskaps are red-purple inside. Green inside means wait.

Cherries. Deep colour for the variety, taut firm skin. Taste one from each block, because varieties ripen in sequence and differ enormously. Always pick with the stem attached or they will not keep a day.

Taste as you go

Every farm expects it, within reason, and it is the only test that settles the question. If the first three berries from a row are sour, move rows and ask which block is picking best. Staff know, and they would rather tell you than have you go home disappointed.

One more thing that is not ripeness

Size is variety and water, not sweetness. The biggest berry in the row is very often the blandest one.
