"Business is booming, the weather's great, the crowd's happy, the stallholders are delighted - what more could we ask for?" Promote Dunstan president Rory Butler said.
The volunteer group organises the event and with 29 food stalls and wine from 23 wineries and wine producers in the Clyde, Earnscleugh and Alexandra basin, the crowd was spoilt for choice this year.
Three Miners co-owner Jeff Price said the day had exceeded his expectations.
"We've sold a large amount of wine. I don't want to say exactly how much, but we brought a lot along and we've had to restock and we're only half-way through the afternoon.
"This event is the premium showcase for wines from this region and it's fitting that the 10th anniversary festival is proving such a success. I'd say it's the best ever and we're certainly super-happy with how the day's gone, " he said.
Mr Butler estimated the crowd at a similar size to last year - 5500 - and said the event attracted regulars who travelled from all over New Zealand to attend.
"Everyone's done us proud this year and it's nice to see so many old faces back here again from all over the country. The festival has lived up to its reputation as the biggest wine event in Otago."
Proceeds from the day are used for various community projects. In the past 10 years, the festival committee has poured $20,000 back into community events.
During that time, funding has been given for brochures, the Clyde New Year's Eve party, the Alexandra Thyme Festival, an annual viticulture industry student grant, an information kiosk and sponsorship for a young person to attend a Rotary leadership course.
Community groups in Alexandra and Clyde have also benefited from the festival.
A survey carried out two years ago revealed the festival injected about $500,000 into the local economy.
