Two methods, two cheeses
Strip away the marketing and cheddar divides cleanly into two categories. Clothbound cheddar is wrapped in muslin smeared with lard or butter, then left to age on wooden boards in a store where air can move around it. Block cheddar is sealed in a plastic vacuum pack from the moment it is pressed, maturing in a closed, airless environment. Both are called cheddar. Both begin from the same curd. What happens next is entirely different.
What the cloth does
In a clothbound truckle, the muslin is porous. Moisture escapes slowly over weeks and months, concentrating what remains. Fats and proteins break down unevenly across the wheel — the outer layers lose moisture faster than the core — and this variation produces the complex, savoury-mineral depth that sets a well-aged clothbound cheddar apart from anything that comes out of a block.
The rind is a living surface. Moulds establish themselves on it — grey-green, sometimes dusty white — and while they do not penetrate deep into the paste, they contribute to flavour development beneath. Cheesemakers turn and grade the truckles by hand throughout ageing, checking for cracks that could admit unwanted moulds and managing the rind throughout. It is skilled, attentive work.
Texture reflects all of this. Slow moisture loss concentrates the proteins, making the paste drier and more granular with age. Long-aged examples develop white crystals — tyrosine and calcium lactate — that give a satisfying crunch against the crumble. This is not a flaw; it is the direct result of extended, open ageing.
What plastic does differently
A block cheddar retains all the moisture it had when it went into the wrap, maturing in its own whey. Conditions stay uniform throughout. There is no rind, no variation from edge to centre, no evaporative loss. The result is a smoother, more pliable, consistent cheese — qualities that are genuinely useful for cooking or feeding a crowd reliably.
Flavour develops in sealed block cheddar, but it travels in one direction: a cleaner, sometimes slightly tangy note without the earthy complexity that open ageing produces. Melted onto toast or stirred through a sauce, a well-made block cheddar is entirely appropriate. Eaten in a wedge alongside a sharp pickle or a dense fruit bread, a clothbound version behaves quite differently — and a block cannot replicate it.
Why clothbound costs more
The price gap is not primarily about tradition or prestige. It is about physics and labour. A clothbound truckle loses a meaningful proportion of its original weight to evaporation during ageing — weight the maker paid to produce and can no longer sell. The longer the ageing period, the greater the loss.
Add the skilled time required for turning, grading, and rind management, plus the board space the truckles occupy throughout maturation, and the economics become straightforward. You are paying for what evaporated, for the person who checked it, and for the store space it held. Block cheddar loses virtually nothing to evaporation, stacks efficiently, and requires far less handling. Its lower price accurately reflects its production costs.
How to read what you are buying
A rough rind dusted with natural mould, or the visible impression of muslin pressed into the surface, tells you the cheese aged with access to air. A smooth, slightly waxy surface with no rind tells you it was sealed. Both can be excellent; the question is which character suits the occasion.
If a clothbound cheddar also carries the West Country Farmhouse Cheddar PDO label, it comes with additional guarantees about provenance and milk — something we examine in our article on that protected designation. The cheddaring process itself — the stacking and turning of curd that gives the cheese its name — is the same in both styles, and our piece on that process explains what happens before the ageing choice is made.
What the cloth or the plastic decides is the trajectory from that point forward. One opens the cheese to its environment, accepting loss and variation as the price of complexity. The other closes it off, preserving consistency and yield. Knowing which one you are holding helps you use it well.
