Juice and Smoothies
Juicing removes the fibre and keeps the liquid. Blending keeps everything and breaks it down. That single difference explains most of what separates the two glasses.
A juicer separates liquid from pulp, producing something thin, bright, and quick to drink. A blender keeps the whole fruit or vegetable and shears it into a suspension, which is why a smoothie is thick and why it holds together longer.
Both are perishable in ways that packaged drinks are not, and both change noticeably within minutes of being made. How each process works therefore decides how the result has to be handled.
Yield is where the two machines separate, and it depends on the produce. Leafy greens give up very little in a centrifugal juicer and a great deal under a press, while carrots and apples yield well either way.
Both drinks change within minutes of being made.
Juice separates and dulls as it oxidises, and a smoothie thickens as the fibre in it takes up liquid.
Thickness in a smoothie is a texture target rather than a recipe. Frozen fruit and the amount of liquid decide it, and a bowl needs to hold a topping where a glass needs to pour.
Order in the jug decides whether the blend works at all. Liquid at the bottom, soft items above it and frozen on top gives the blades something to circulate.
Sweetness in a juice comes from the produce and cannot be turned down afterwards. That is worth knowing before a glass is built entirely from fruit.
