Vintage Report: Porongurup, Great Southern, WA

The 2024 vintage was definitely one of the earliest vintages the region has experienced.

“A wet June topped up our dams and meant we started the season in good shape. This turned out to be very, very important as the season progressed,” says Castle Rock Estate owner and winemaker, Rob Diletti.

From the beginning of September 2023 to the end of April 2024, there was a total of 162mm of rain, 116mm of that fell before the new year, with 46mm from January to the end of April.

Apart from two days topping 40 degrees, there was not sustained excessive heat, but it was still a warm year.

“We maintained good vine health and adequate leaf cover through well managed irrigation, as well as altering our canopy management regime to suit the warmer and dryer weather conditions.

“Vintage started nearly four weeks earlier than last year, and was certainly very frantic. That said we are extremely pleased and proud of the wines that we produced.

“This was achieved by maintaining our irrigation throughout harvest, careful monitoring of the vines as well as the grapes, and picking immediately when needed.

“Having our own harvester again proved to be critical in this process, enabling us to pick the grapes at optimal ripeness and delivering them to the winery immediately.”

“As always the stand out wines from the Porongurups are Pinot Noir and Riesling, highlighting our unique site’s suitability for these varieties.”

Since the beginning of May the region has experienced 30mm of rain, providing hope of a wet winter to restore soil moisture and water reserves.
