Real maple syrup has a distinct flavor and consistency that is difficult to replicate. To ensure you're purchasing authentic maple syrup, check the label for 100% pure maple syrup and avoid products with added sugars or artificial flavors. You can also look for certification seals from organizations like the USDA or the Federation of Quebec Maple Syrup Producers. All USDA Grade A maple syrup must be 100% pure with no additives and have a minimum density of 66 brix, equal to 66% sugar.
