The Japanese do, it's called sake, but that's not a German-style lager beer. I always used to think it was funny that Budweiser says right on the label 'This beer is made from the finest malt, corn and rice.' That's like a wine label saying 'This wine is made from the finest grapes, potato-peelings and antifreeze'.
What is Guyabano? Guyabano is a fruit that comes from the Graviola tree. Other names for guyabano (name known in the Philippines) include: guanÃ¡bana (Spanish), graviola (Portuguese), pawpaw (in Brazil), corossol (French), soursop (English), and custard apple (English). The scientific name is annona muricata.
Guyabano tea is easy to make. Simply add a few dried guyabano leaves to a pot with boiling water. You should turn off the flame when the water is hot enough and cover the pot, leaving the graviola to steep in the hot water for at least two minutes. You can adjust the number of leaves you place in the pot to your taste.
