Do Roasted Nuts Spoil Quicker Than Regular Ones? - Tasting Table
Briefly

Roasting nuts at home can transform their flavor into a crispy, complex snack. However, it shortens their shelf life due to oil exposure to oxygen during the heating process. Typically, roasted nuts last between one to three months at room temperature, while professionally packaged variants like Blue Diamond Almonds can last one to two years. To preserve freshness, it's advised to store roasted nuts in airtight containers in cool, dark places, such as the refrigerator or freezer, away from strong odors.
Roasting nuts enhances flavor but decreases shelf life; they're best enjoyed within 1-3 months if stored properly.
