Brewfest food while not in in the brewfest event

[Yavanna]

This is my second thread so I hope it's useful.
In the brawler´s guild zeppelin there is a npc called Haxxil Drinkmeister who sells drinks that are only sold during the Brewfest event and give nice buffs, like tue Crimson Stripe, which gives you a +40 crit buff for one hour. They are not soulbound so you can mail them to your alts or friends.
Not really a big exploit but can be useful for alts
