More about Maple

The colour and flavour of maple syrup changes in subtle ways during the seasonal harvest.

At the start of the sugaring season, the syrup is generally clear, with a light, sweet taste. It becomes darker with a caramelised flavour as the season progresses throughout the spring.

An unopened can of maple syrup keeps for many years.

Once the can is opened, syrup should be kept in an airtight container in a cool place.

100% pure maple butter doesn't contain any butter, or dairy products.

Like all 100% pure maple products, maple butter comes from the sap of the maple tree – that’s all.
