Roland Birr, Önologe und Wine Edutainer
"The ONEforALL glass is my constant professional companion de-mystifying wine & food all over the world since over 20 years now. It works like a chimney and almost “extracts” the aroma of the wine bringing it straight to the tastebuds. It is its simplicity which convinced me long time ago."
