In an innovation this year, volunteer guides Barbara Kerr and Stephen Roe will provide free history tours of the 135-year-old heritage site, giving visitors a colourful glimpse into the wider area's busy gold-mining past.
Mr Roe said brewing had sprung up almost as soon as the first wave of thirsty miners arrived.
"Beer was first brewed in 1863 in Somerset-born Henry Coverlid's Weatherstons' barber's shop. Henry branched out into soda and ginger beer, and sold out of the brewery, after which it changed hands several times, before ending up with [current landowner Ben Hart's great grandfather] Ben Hart and J.K. Simpson in 1884."
At that point the business had expanded rapidly, eventually growing to supply the area from Canterbury to Bluff.
It was shut down in 1923 after being bought by NZ Breweries.
Mr Hart was also an enthusiastic gardener and, from 1895, he was responsible for planting up 25 acres (10ha) around the brewery, including a wide range of daffodils and rhododendrons, which remain today.
Weatherstons Brewery and Daffodils Trust secretary Mel Foster encouraged visitors to come and enjoy the blooms, history and atmosphere of the "unique" site.
"We just need a few days' sunshine to set the daffodils off properly, but it's a beautiful place at any time."
The site would open 10am to 4pm, Friday to Sunday, from September 6 to October 13. History tours run from 2pm each Saturday, except October 5.
There is a small entry fee.
