The `Harry Potter` actress has revealed her parents Chris and Jacqueline - who are both lawyers who divorced when she was just five - always treated her like an adult and she was allowed to drink wine with meals as a child.
Emma, now 20, believes her parent`s attitude to alcohol stopped her from drinking to excess as a teenager like many of friends.
She said: "My dad wouldn`t have any of this kids stuff. We would never be allowed to order from the kids` menu in restaurants. He`d always expect me to have adult conversations. I wasn`t babied I was expected to step up when I was told to. I was never not allowed alcohol - I was seven when I had my first glass of wine, mixed with water and with a meal. I found it really strange when I got to school and everyone was like, `Ooh, we`ve got alcohol!` I wasn`t interested."
Emma spent a lot of time from her parents shooting the eight `Harry Potter` movies - in which she plays Hermione Granger - and although she wishes should could have seen more of them while growing up she is very grateful for the experience.
She added to The Sunday Times Magazine: "I would never have forgiven my parents if they`d stopped me from having this amazing opportunity. What has been hard is making eight blockbusters back-to-back throughout the whole of my teenage years. If it was my daughter I would prefer to be just one or two movies . I was a long time away from my mum. Dan (Daniel Radcliffe) and Rupert`s (Rupert Grint) parents gave up their jobs to be with them. Neither of my parents did. But both my parents love their work and it`s a big part of their identity."
