One of the local attractions in Greymouth is the Monteith's Brewery. We took a tour, which was very interesting, but the highlight was definitely the taste test at the finish. We all had small samples of the various beers, and then were left with 15 minutes of "open bar", where we could pour as much of any beer we wanted.
For a $10 tour, that is quite a bargain!
I'm the bartender!
