How to Tell if Stilton is Still Fresh
Identifying the signs of aging in this iconic blue cheese.
Stilton stays fresh for 3–4 weeks in the refrigerator when wrapped properly.
Stilton is a prestigious blue cheese known for its distinct buttery texture and sharp, complex flavor profile. Because it is a dense, aged cheese, it possesses a relatively sturdy structure compared to softer varieties like brie. However, even this robust cheese can eventually degrade if left in the refrigerator for too long or exposed to improper conditions. To maintain its peak quality, Stilton should be kept tightly wrapped in wax paper or foil to prevent it from drying out and becoming crumbly. Learning to spot the subtle changes in texture and aroma helps you enjoy this gourmet staple at its best while ensuring your cheese plate remains safe and delicious for every gathering.
