What does graining maple syrup mean?

Graining maple syrup refers to the crystallization process that occurs when syrup is cooled or improperly stored, leading to the formation of sugar crystals. This can happen if the syrup is not filtered well or if it is stored for an extended period. While grained syrup is still safe to consume, it may have a grainy texture and be less appealing for use as a topping. To prevent graining, it's essential to maintain proper storage conditions and use the syrup within a reasonable timeframe.
