Key Highlights
- Blue cheese develops its characteristic veining through the intentional introduction of Penicillium roqueforti or Penicillium glaucum moulds.
- The piercing process during ageing creates air channels that allow blue veins to develop throughout the cheese wheel.
- Flavour intensity varies dramatically based on ageing duration, milk type, and mould strain used
- Storage and serving requirements differ significantly from other cheese varieties due to active mould cultures.
Introduction
Walk into any proper cheese shop, and you’ll notice blue cheese occupies its own dedicated section, often wrapped separately and stored with particular care. This segregation isn’t mere snobbery or marketing theatre. The fundamental production methods, ageing requirements, and flavour development pathways distinguish blue cheese so substantially from other varieties that comparing them requires understanding an entirely different approach to cheesemaking.
The Mould Makes All the Difference
Cheesemakers intentionally introduce specific Penicillium cultures into blue cheese during production. These aren’t accidents or contamination but calculated additions that define the final product. Other cheeses might develop surface moulds during ageing, but blue cheese incorporates mould throughout its entire structure from the beginning.
The mould spores get mixed directly into the curds or sprayed onto them before pressing. This even distribution ensures veining appears throughout the finished cheese wheel rather than concentrating in specific areas. Roquefort, Stilton, Gorgonzola, and countless regional variations all rely on this deliberate inoculation, though each uses different strains that produce distinct flavour profiles and visual characteristics.
Hard cheeses like Cheddar or Parmesan never see intentional mould introduction during their making. Their ageing processes focus on moisture reduction, protein breakdown, and flavour concentration through entirely different mechanisms. Soft cheeses like Brie develop surface moulds that remain external, never penetrating the paste itself.
Piercing Creates the Signature Veins
After initial pressing and salting, cheesemakers pierce the blue cheese wheel with long needles or skewers. These holes create channels that allow oxygen to penetrate deep into the interior, and oxygen is precisely what the Penicillium cultures need to flourish and spread their characteristic blue-green veining throughout the paste.
Without this piercing step, the mould would remain dormant or develop unevenly. The oxygen access triggers growth along the channels, creating those dramatic marble patterns that make blue cheese instantly recognisable. Timing the piercing correctly requires experience, as doing it too early or too late affects the final vein distribution and flavour intensity.
Traditional cheeses skip this step entirely. A proper cheese wheel of Gruyère or Manchego develops its characteristics through time, pressure, and carefully controlled humidity without requiring oxygen channels. Their dense, uniform textures result from keeping air out rather than inviting it in.
Flavour Development Follows Different Rules
Blue cheese develops sharp, pungent, often metallic or mineral notes as the mould cultures metabolise fats and proteins within the paste. The intensity builds over weeks or months, depending on the variety. Young blue cheese tastes relatively mild with subtle tanginess, whilst aged versions deliver aggressive, complex flavours that coat your palate and linger.
The mould itself contributes much of this flavour. Penicillium roqueforti produces compounds that create the characteristic bite and aroma that some people adore, whilst others find overwhelming. This isn’t just aged milk flavour but something fundamentally different, created by living organisms transforming the cheese from within.
Compare this to aged Gouda or Comté, where extended ageing produces crystalline crunch, nutty sweetness, and savoury depth without the sharp, almost spicy notes that blue cheese delivers. These traditional varieties develop complexity through enzymatic breakdown and moisture loss rather than active mould metabolism.
Storage and Handling Requirements
Blue cheese remains a living product throughout its shelf life. The mould cultures continue working even after you bring the cheese wheel home, which means storage conditions significantly impact how it tastes from week to week. Proper wrapping prevents the mould from spreading to other cheeses in your refrigerator whilst maintaining enough air circulation to keep the blue cultures alive.
Many cheese enthusiasts wrap blue cheese in parchment or specialised cheese paper rather than cling film, which can suffocate the mould and create off flavours. Temperature fluctuations affect blue cheese more dramatically than hard varieties because the active cultures respond to environmental changes.
Most other cheeses tolerate standard refrigeration with less fuss. Hard varieties survive longer without degradation, and soft cheeses primarily concern themselves with preventing exterior mould growth rather than maintaining internal cultures.
Pairing and Serving Considerations
The assertive flavours of blue cheese demand different pairing strategies than milder varieties. Sweet accompaniments like honey, figs, or port wine create contrast that highlights both the cheese’s intensity and the sweetness. The combination works because blue cheese’s saltiness and sharp notes need balance rather than amplification.
Mild cheeses pair beautifully with subtle crackers, light wines, and delicate fruits that won’t overwhelm their nuanced flavours. Blue cheese laughs at subtlety and performs best alongside bold companions that can stand up to its personality without getting lost.
Conclusion
Blue cheese occupies a distinct category within the broader cheese world due to its intentional mould cultivation, unique ageing processes, and flavour development that relies on living cultures transforming the paste from within. Understanding these differences helps you appreciate why this variety commands particular storage, handling, and pairing approaches.
