I'm not so sure of others on this site, but being a beginner myself, with only 1 batch completed (i.e. skulled), and 2 more in the spout, I would like to offer the advice of brewing a tea (regular black, or Earl Grey, I used Dilmah) and using this instead of plain water. I followed according to this recipe:

Sorry don't know how to link it properly, copy and paste into your browser if it doesn't work. I did this recipe for my birthday (which was only a month away), and the results were great. It was clearer than crystal, and very very smooth, even at only 1 month old. I was on the cheap, so seeing as I only had one vanilla pod in the cupboard, I used that and no extract. Even in just a gallon, the flavour of vanilla is totally absent, even if you picture it while tasting. Fermented for 2 weeks, racked, left in secondary for 2 weeks, then bottled the day or 2 before the event. 1 bottle of 4 is left (now about 6 weeks in the bottle). I cracked the third last week and it was gooood. I hope my next batch hurries on up so I can save the last of my first batch til next year!
Honestly though, I think the tea is a properly good idea (the resulting drink has no detectable taste of tea at all, even the colour is pale after ferment). It must have tannin or nutrient that the yeast can use, and which is absent in plain honey.
Good luck with the wedding by the way!
