Filtration

Definition

Straining removes wax fragments and bee parts through a coarse mesh and leaves pollen intact. Fine filtration under pressure, usually with the honey warmed, removes pollen and the micro-particles that crystals nucleate on — which produces a clear product that stays liquid far longer on a shelf. Ultrafiltration goes further still and removes pollen entirely.

Where the word gets used loosely

Fine filtration is the reason a supermarket jar is still pourable after a year, and 'runny means fresh' is therefore backwards — raw unfiltered honey usually sets sooner precisely because it retains the particles crystals form on. Removing pollen also removes the evidence a laboratory would use to establish floral and geographic origin, which is why ultrafiltered honey is treated with suspicion in authenticity work.

Guide records that discuss this

• Raw, filtered and processed honeyWhat actually happens between the hive and the jar, which of it changes the honey, and why the word 'raw' carries less information than it appears to.
• What makes a honey taste floralFloral character comes from volatile aroma compounds that survive the journey from flower to jar. Very few do, which is why genuinely perfumed honeys are a small minority.
• How honey is gradedHoney grading measures colour, moisture, clarity and flavour defects. It says almost nothing about how good the honey tastes, which is a deliberate limitation rather than an oversight.
• How to read a honey labelSome words on a honey jar are legally defined. Most of the prominent ones are not, and the difference is not signposted anywhere on the packaging.
• Pollen analysis explainedMelissopalynology — counting and identifying the pollen grains in a honey under a microscope. It is how monofloral claims are substantiated, how geographic origin is challenged, and it is far less straightforward than it sounds.
• European honey standardsThe EU honey directive turns the Codex definition into binding law across the single market, adds labelling rules, and was substantially amended in 2024 — with the new origin-labelling regime in application since 14 June 2026.
• From hive to jarThe bees finish the honey when they cap it. Everything after that is people: deciding there is a surplus, taking some of it, and choosing how much to do to it on the way to a jar. Most of what separates one honey on a shelf from another happens in this half.

Question records that discuss this

• Is raw honey better than ordinary honey?Better for flavour, yes — raw honey keeps aroma compounds, enzymes and pollen that heating and fine filtration remove. Better for health, no: there is no good evidence that any of that produces a benefit. And 'raw' has no legal definition in most markets, so the word on a supermarket jar guarantees nothing.
