North London brewery Beavertown is to hold a block party at its N17 home on Saturday 29 June.
The day will be divided into an 11am-4pm session with child-friendly outdoor activities and a 6pm-11pm session that is for over-18s only.
More than 30 draft lines will be available, as well as a range of food stalls.
All beer is included in the price of the ticket, but pours are limited to one-third pints.
Beavertown's beers include American pale ale Gamma Ray. Heineken acquired a minority stake in the business last year.
