The country house hotel launched in April last year and was the first major project for the chef following his departure from Gidleigh Park in Devon after a 21-year tenure that saw him retain two Michelin stars for 17 years.
Lympstone Manor's restaurant won a star in the 2018 Michelin Guide for its 60-cover fine dining offering.
It is also set to begin producing its own sparkling wines, and marked its one-year anniversary by planting 18,000 vines in its 28-acre grounds last month.
“Since opening the hotel in April last year the team has continued to work hard to offer every guest a fantastic experience so it’s great to see our offering reflected by this prestigious accolade,” says Caines.
Gary Baldwin, senior hotel and restaurant inspector and area manager at the AA, says the hotel showed “consistency and quality” following a series of inspections.
“Our inspectors were impressed with the physical quality of the property, a true hands-on vision from Michael, excellent attention to detail and quality noted throughout,” says Baldwin.
“This official star grading is only the beginning of the Lympstone journey, with exciting plans ahead to make this an even greater destination.”
