Thoughts up to now from research...

I think that I am going to keep the shape of the bottle currently as I think this really works it practical and looks effective, I am going to make the neck of the bottle smaller and grip of the lid and neck tighter due to the use of the same material. When I open bottles of Purdey's it always runs down the neck before opening the bottle fully. 

I am going to use an aluminum bottle as I wanted to keep the silver effect but I didn't see the need of a sleeve. So therefore I thought the use of printing on to the bottle itself would be more practical for the environment.

I am going to play with lettering for the bottle, to describe the ingredients as this is something that was a common theme from possible customers, that the drink was too secretive for them to spend on an expensive drink that they don't now if they are going to like.
