Nettle Tea Fertilizer .... when is it made ?

Last year I saw on Gardeners World Monty making nettle tea, which I tried. My tomatoes did very well indeed, so I am keen to try it again this year .... especially as I now have an allotment as well as a back garden greenhouse.

My question is .. when should I make the tea ?

There are a lot of nettles growing near the allotments, so I may as well get there before somebody else. Maybe the leaves aren't ready yet for the tea, which is the reason I'm asking now.

Last year, following Monty, I just went out in the car, stopped at the nearest lay-by and found enough nettles for my project. This year, I'll need more.

thank you for any advice provided

Now is as good a time as any 

Don't do what I did and forget to wear gloves. Ouch!

You obviously didn't grasp the nettle! Being serious, I have seen my neighbour pulling them out with her bare hands, so maybe there's something in it?

You can hold the leaves by the middle & not get stung - not sure I'd want to grasp them though!
