The 'Grease' actor, who has children Ella, 12, and Benjamin, two, with wife Kelly Preston, said the sweet drink reminds him of Christmas, and he loves the way different varieties from around the world have very different tastes, reported Femalefirst.
"It represents winter wonderlands, it represents Christmas. I've collected various types of cocoa from around the world," he said.
Travolta, 58, also explained that people should be careful how they handle cocoa powder because any impurities from air or touch can affect its quality.
"Never blow on it. Like a fine wine, it changes the quality of the chocolate. So, never, ever blow on it," he added.
