Jenny McDonald and Sue Stockwell, of Dunedin Craft Distillers, said they were thrilled to be selected as one of "21 culinary gems worth a trip in 2024".
"We were just shocked," Ms McDonald said.
"We started this back in 2020 off practically a blank sheet of paper and a desire to prevent food waste going to landfill."
On the Bread and Bottle tour, visitors learn how the co-founders turn surplus baked goods — croissants, bagels and even pizza dough — into gin and vodka.
"It’s been quite a ride," Ms McDonald said.
"We love seeing the look on people’s faces to see what we started with, and what the final product looks like.
"We’ve met lots of really interesting people."
What began as something of a hobby had since turned into something a lot more serious, Mrs Stockwell said.
"We’re no longer thought of as simply two old ladies giving it a go.
"It’s been really worthwhile."
Although they were surprised by the accolade, the tour did offer a point of difference, they said.
"It shows that you can do a lot with bread," Mrs Stockwell said.
"So far, we’ve processed more than 9 tonnes of bread, which is pretty good going for two old bats dotty about gin."
