Kale, spinach and cucumber: what each green contributes to a juice

Kale: the strong one

Kale is a brassica, cousin to cabbage and broccoli, and it juices like one: deep-flavoured, slightly peppery, unmistakably green. It's also one of the most nutrient-dense leaves in common use. Kale is particularly known for its vitamin K content, alongside folate and carotenoids, which is a large part of why it earned its reputation in the first place.

In juice, kale needs partners. On its own it's austere. Balanced with cucumber and a little apple and lemon it becomes drinkable without losing its character, and that's the architecture of Balanced Greens, our kale-led juice.

Spinach: the smooth one

Spinach is the diplomat of green juicing. It's mild, slightly sweet and blends into a juice without dominating it, which makes it the ideal leaf for anyone easing into greens. Nutritionally it's the leaf people associate with iron and folate, and it also carries magnesium and vitamin K, as leafy greens generally do.

Spinach anchors Core Greens and appears in Fresh Greens, precisely because it delivers the green without the fight.

Cucumber: the body of the drink

Cucumber is around 95% water, and in a green juice that's its job: it's the volume, the coolness and the reason a green juice drinks light rather than thick. It contributes a clean, faintly melon-like freshness that rounds out sharper leaves. Almost every green juice we make uses it, because a juice built only on leaves would be a shot, not a drink.

Celery: the savoury backbone

Celery brings water too, but with character: a savoury, gently salty note that comes from its natural mineral content, including potassium. It's the ingredient that makes a green juice taste grown-up. Celery is enough of a subject that it has its own section of The Pulp and its own juices, but inside the green range it plays the supporting role, deepening the flavour of Core Greens and Fresh Greens.

Parsley: the seasoning

Used in small amounts, parsley does for juice what fresh herbs do for cooking: it lifts everything. It's intensely aromatic, grassy and bright, and like other dark greens it's a concentrated source of vitamin K for its weight. You'll taste it in Fresh Greens, where it sharpens the apple and spinach into something fresher than either alone.

What this means when you choose a juice

Read the greens on the label the way you'd read a recipe. Kale-led means bold and peppery, spinach-led means smooth and mild, and the more cucumber and celery, the lighter the drink. Because vitamin K, folate, iron and magnesium travel with the dark leaves, the leafier the recipe, the more of the leaf's character, in every sense, ends up in the glass. Vitamin K, for what it's worth, is the nutrient the official register connects to the maintenance of normal bones, which is why dark leafy greens keep coming up in that conversation. We cover that properly on our bone health page, and the iron and folate side, where the tiredness-and-energy functions come in, on our energy page.

The greens, by their lead leaf

Each of these leads with a different green, so pick by the character you want:

The whole range is in the green juice collection, and if you're starting from zero, begin with what green juice is actually made of.

The bottom line

So "greens" isn't one thing. Kale brings the bold, peppery depth, spinach the smooth easy green, cucumber the light and the water, celery the savoury backbone and parsley the lift. Read the leaves on any label like a recipe and you'll know how the juice will taste before you open it. Kale-led and full-flavoured is Balanced Greens, and if you're new to any of this, start with what is green juice?
