I still have a bottle of Le Sarrasin from a while back. I am trying to figure out how it is trading. I traded one before and think I might have gotten the short end of the stick value wise and want to try to avoid that this time. http://www.beeradvocate.com/beer/profile/22511/112082/
I traded one for some Bruery Sours last time. And nothing super difficult to get just stuff you need to be a member to get. I was hoping this time it could help me get some of my more highly desired beers/hard to get beers.
I traded an Atrial and a Nocturn for Sarrasin. Not sure why you think you got the short end of the stick when talking about multiple members-only beers of a club that you aren't a member of, but I know there are details I'm unaware of. Anyway, what kind of beers are you interested in? What do you consider highly desired? Answering these questions will lead to the answer to your original question about Sarrasin.
Depending on the beers, that sounds about like the medium sized end of the stick; seems fair. Over on $$s probably considering Bruery prices, though Sarrasin wasn't cheap either. Though not trivial to get, quite a bit of Sarrasin was made, right? Wasn't it over 2K bottles?
