The wine made by the Ewok species from the forest moon Endor was less strong and more sugary compared to the excessively powerful wine created by the Yuzzum, a different species also living on Endor. To make the Yuzzums' wine safe for consumption by other species, it could be mixed with the Ewoks' wine.
This wine appeared in "The Wine in Dreams," a short story penned by Mira Grant and featured in the Canto Bight collection of novellas released in 2017.
