I used a 1/4 oz at 15 min for a five gallon batch of bragot (to avoid using hops; my inexperience at AG turned it into a nut brown ale) and was able to drink it after cooling without issue. It may have been the 20# of malt that balanced it out or the Brewer's Best wormwood wasn't up to snuff. Just added honey to the secondary and I'm waiting a bit before adding candied ginger, peppercorn, star anise, etc.
It does contribute a particular herbal, woodsy taste beyond the bitterness and not just supposed mind effects. As with all things it needs to be used right.
I think there is some novelty in something that was bittered with a component other than hops. Using wormwood is also another way of exploring beer in a manner which you probably won't find in commercial beers. I'm more about the old-timey appeal (because
wormwood was so hyped in the past even if it has been shown to be ineffective in the present time) and my fancy for the works of Poe and Lovecraft where wormwood becomes more or less a plot point or motif. I think these are valid points for some.
As far as hallucinogenics, I'm a bit of a hypochrondriac so it'll probably do something for me anyway (had an interesting run with hookah one time).
I am surprised friday was able to bring it to a competition though since technically there are warnings on some of the components to wormwood. I wouldn't let someone drink it without letting them know what was in it, but I guess contests come with some of the disclosure up front?
Wormwood may be impotent to the drinker but it certainly stirs up potent feelings on forums.
