Even for experienced wine lovers, she feels that it is about "being given inspiration on what new wines are out there".
"The great thing about wine is that it's a vast world, so to be offered wines via ST Wine that are maybe outside of your comfort zone, and to experiment and try something new - I think it could be of interest to people who already know quite a bit about wine," she adds.
The ST Wine subscription comes with free access to the Robert Parker Wine Advocate online portal - which typically costs $140 a year - offering reports and a vast database of tasting notes that wine lovers will find useful.
Ms Perrotti-Brown is a Master of Wine, one of the most prestigious titles in the wine world awarded by the London-based The Institute of Masters of Wine.
She took over as editor-in-chief from leading US wine critic Robert Parker at the end of 2012, after an eight-year stint as a reviewer based out of Singapore. The American is now based in the Napa Valley, where Wine Advocate's newest office opened 11/2 years ago.
She heads a team of eight other wine critics, including Parker, covering "almost all wine regions of the world". She herself covers Australia and New Zealand, as well as Oregon and Sonoma.
Having most recently spent time in New Zealand for Wine Advocate's latest report, she is excited about Pinot Noirs from the young wine-growing country.
"As New Zealand's vineyards become more mature, you see the emergence of great wine apart from the usual Marlborough Sau- vignon Blanc," she says.
Robert Parker Wine Advocate is not limiting itself to just wines. In August last year, it introduced a ratings guide for sake for the first time, with 78 bottles ranked by Chinese critic Liwen Hao, who also critiques wines from Asia for the publication.
Ms Perrotti-Brown says that bringing sake into the fold was a decision based on increased interest in global markets and cities such as New York, London and Singapore.
The highest ranking was awarded to sake from Niigata Prefecture's Kameno-o Sannen Jukusei, with 98 points.
Not long after the scores were released, a new sake exporter based in Tokyo, called The Taste Of Sake, was found to be selling the guide's 78 top-scoring sakes online, leading to suggestions that there were links between Robert Parker Wine Advocate and The Taste Of Sake, with the latter profiting from inside information.
Ms Perrotti-Brown describes the entire episode as "baffling", adding that the guide took the allegations seriously and had its attorneys investigate.
"There was no connection that could be found between the person who set up the tastings for us and the sake website," she says.
To ensure the credibility of the publication and reviews, she adds that the company will organise its own tastings and hire only specialists not affiliated with the trade.
It is looking to publish another sake report at the end of next month and a third in the middle of the year.
As for the possibility of adding a whisky report in the future, she says: "I wouldn't completely discount it, but we don't have any plans in the pipeline.
"For us, it's a matter of our reviewers being experts in that field. Maybe if we find a whisky expert, who knows?"
