What makes a perfect brew?

Throughout the ages, there has been some debate as to what makes a perfect brew...  milk or no milk? Milk first or last? Black, green or white tea? Bag or no?

For me, I use loose tea (the example in the picture is Tea Palace Organic Earl Grey St Clements) and I put them into a tea filter- about a teaspoon and a half of tea. I then let it brew, adding milk (if applicable) afterwards; I like quite a lot of milk! How do you make your tea? 

I'm putting together a post about perfect summer teas- please leave some suggestions in the comments!
