They do, and you won’t go crazy or have any psychedelic experiences from drinking it. I tried it this past weekend, and I’ve written up a review on my beer blog. Bottom line, it’s definitely worth the experience.
On a side note, I have to say I really like the Blacksmith’s happy hour menu—you can get a sizable quality meal for only $10 or 11, not to mention the drink deals. 4:30 to 6:30 (and 9pm to close) every day, I believe. It’s a deal that’s hard to beat.
