I'm currently reading Decanting a Murder by Nadine Nettmann. This book is the first in the Sommelier Mystery series and will be released May 8th.
Katie Stillwell is a sommelier trying to advance in her most difficult profession. Invited to an exclusive wine event at an even more exclusive winery, Katie intends to enjoy the experience and the fine wine. The festivities have barely begun when a scream shatters the jovial atmosphere. The owner of the winery has been found dead, stabbed by a corkscrew and left in a vat of wine. The corkscrew turns out to belong to Tessa, Katie's flighty friend, a winery employee who invited her to the tasting...and Tessa cannot be found. Katie owes Tessa and is determined to use the skills of her profession, and tips her cop father taught her, to nose out the real killer!
