Liquid Gold (maple syrup nickname)

Many liquids have been called “liquid gold” (that is, something very valuable and desired). Maple syrup has been called “liquid gold” since at least 1910 and 1960.
 
Honey has been called “liquid gold” in American newspapers since at least 1925.

To get Vermont’s best thing that’s sold.
