Dandelion has benefits beyond homemade wine that include its usefulness as an herbal medicine

Dandelion is considered by most of us an unsightly, persistent lawn pest. But historically, dandelion benefits included its usefulness as an herbal medicine and food source. The dandelion is native to Europe and Asia and has spread to many of the temperate regions of the world.
The dandelion plant picked up many names over time: Irish daisy, puffball, swine’s snout. Priest’s crown, a medieval name, stems from the green bud resembling a golden-haired seminarian who then matures into a distinguished pastor whose hair turns white and then falls out! In modern French the plant is called pissenlit, which means "urinate in bed", apparently referring to its diuretic properties. Likewise, "pissabeds" is an English folk name for this plant.

Dandelion wine tastes like sherry and is reputed to be a good tonic for the blood. A basic dandelion wine recipe includes:

One gallon of flowers

I understand that it makes a reasonably good white wine, sweet or dry depending on your use of sugar. I will hold out for them to start making dandelion wine in California!
