Once I've sorted this wine out and can vouch for the recipe, I'll write it up here for anyone who might be interested in giving it a go. By the way - if you think you'll be making this wine, get your flowers now while the getting is good. You can always freeze (or probably even dehydrate) the petals for later use. The next wine up for us will be either be rhubarb or hawthorn blossom, depending on which of the two I can lay my hands on sufficient quantities of first.
By the way - does anyone know of a way to send wine through the mail? I'd love to offer some in a giveaway one of these days.
