I've always interpreted the light vs. dark thatch variation as representing differences in materials - dried straw and rushes used for thatching tends to be a bit lighter than reeds and sedges, AFAIK. Aside from that, we have the two variants because they tend to work well respectively with the lighter palettes of the southern regions, and the darker palettes of the northern regions.Yes, I do have a justification for the dark thatch roofing. Thatch is only that yellowish colour when it is new, and realistically, not every single one of these houses is going to have a freshly thatched roof at the exact same moment. So I have decided to use dark thatch to represent houses that have seen more years.
It's elderberries actually. The elderberries are mashed and the juice collected, then put in a container of water, and heated while sugar is added. I believe yeast is added as well.Isn't elderflower wine produced by steeping elderflower in a solution of sugar and water, sometimes lemon, with the elderflower acting as a substitute for yeast. And then that becomes a bubbly light alcoholic drink?
