I asked again what rose, and found the answer by scrolling up. Glad to see you’re getting something so lovely.
Sure hope to start some roses here in '18.
Today I hope to bottle a batch of ale made without hops, but with yarrow and rose hips. Got the rose hips from Midwest Brewing; grew the yarrow leaves here. Used nearly 50 inches of yarrow leaf and one, to one and a half, ounces of dried rose hips. They should provide an interesting citrus note to the ale.
Yarrow - and mugwort, sweet woodruff and some others - have coumarin. It gives you a boost if used in reasonable quantity. No aftereffects. However, I once tried twice as much yarrow, alone in a brew. Made the heart hammer half the night! Had to drink it midday in order to sleep the following night. Ale kept very well with yarrow on duty to keep it pure.
