Meadow Sweet Champagne Recipe

This is a lot like Elderflower Champagne but using Meadow Sweet insteat of Elderflower. The Meadow Sweet comes out just as the Elderflowers finish (it grows in damp areas). This idea came from here but I used the same recipe as we use for Elderflower Champagne
This is a small batch, I like to make a number of small batches that fit easily in to a pan and aren't a major time investment to bottle. It also means they come ready over a period of time rather than a huge amount ready to drink at once.

10 heads of Meadow Sweet (or a bit less if they are big ones)
300g Sugar
3.5 l water (or thereabouts - I use the bottles I am going to put it in to mature to measure the water)
3 desert spoons white wine vinager
Juice of one lemon (and the rind)

Bung everything in a pan/bucket. Stir and leave for 24 hours (still occassionaly if you can be bothered)
Bottle.
Will be ready to drink in about 2 weeks, if the bottles (best to use plastic) seem to be bulging then let some pressure off (carefully).
Drink chilled.
