Hi there,
You are referring to the
Brewers Festival in Portland. It is held in mid-July at the Tom McCall Waterfront Park and last four days.The festival showcases local brewers latest creations and traditional favorites.
The city of Portland is renown for great micro brews, and has more microbreweries per capita than almost any other city in the world. There is no admission fee to get into the Festival and beers are roughly $4.
Be advised that hotels do fill up quickly during the Brewers Fest so, book well in advance your
hotel accommodation.
Hope this helps
