The couple are excited about their latest business venture, which also includes a five-unit motel.
It is a major change from their farming operation on the Taieri, which includes a dairy farm, using a sharemilker, along with their beef cattle and sheep.
Mr Adam, a third-generation farmer in the area, remains passionate about the agricultural sector.
Things have moved quickly since the couple first heard the Black Swan was for sale and they took a first look only about three months ago.
Mrs Adam has always enjoyed cooking and baking. A full-time stint as an Australian outback station's cook whetted her appetite for owning a cafe.
With the couple's three children, aged from 15 to 20, growing up, she decided it was time for a new challenge.
There was never a doubt they would retain the Black Swan name.
"You could change the name but everybody would still call it the Black Swan," Mrs Adam said.
While she admitted a little nervousness because of the "huge expectations", her husband had no doubts she would take it in her stride.
"She's a perfectionist," he said.
While Mrs Adam expected to be doing mostly baking, Mr Adam was more likely to be out on the farm.
"I can't cook. I can boil toast.
"I'm just the support person," he joked.
"When I need something lifted, I'll be calling him," his wife said.
The couple said they had a "great team" of staff and they were looking forward to serving good cafe food and lunches.
Southern staple the cheese roll was definitely on the menu, with Mrs Adam promising an old-fashioned, "very tasty" family recipe.
The premises have been freshened up for reopening, but were "still quite cosy".
They aimed to cater for everybody, but were not doing takeaways.
The couple had plans for further redevelopment and called the venture a good challenge.
"My father used to say: 'You've got to bite off more than you can chew, and then chew it," Mr Adam said.
