The 2023 growing season started off cold and wet. For the first time since 2011 their dam was full, and in fact overflowed for most of October and November (rainfall for the calendar year of 2022 was 800mm). Budburst was slightly behind average timing, but crops were down significantly: the bunch counts were low in the first place, we had a mild frost in September and the wet weather finally caught up with them via downy mildew. The rain stopped at the end of December.
The overall heat accumulation was the same (1338 Growing Degree Days) as 2021, both seasons on the slightly cooler side of average but differing in that the heat for 2023 was more toward the second half of the season. Veraison occurred in February and then we picked Chardonnay, Pinot Noir, Gamay, Sauvignon Blanc and Riesling in March, and Shiraz and Cabernet/Merlot in the first week of April. The picking weather was pleasant and the fruit arrived at the winery in very good condition. While quantity was down (especially in Pinot Noir) quality was good: fresh acidity, concentration, colour, tannin and steady fermentations have us looking forward to bottling, and seemingly warmer and drier seasons as El Niño returns.
The estate comprises 24 vineyard blocks, 8 grape varieties and 16 clones. The soil is generally low-fertility with good drainage, allowing for controlled growth but rich enough that our organic farming principles only require the addition of compost to maintain vineyard balance.Subtle but important soil variations are the result of a continuum of volcanic surface debris and ancient sea beds running to richer and darker soils, layered over predominantly limestone bedrock. The first vineyard was planted in 1974, with subsequent plantings through to the early 1980’s, making our vines some of the oldest in the Geelong region.
Like their predecessors, the team at Bannockburn do their best to express the vineyard through the wine we produce, telling a deeper story of soil and site. Their viticultural principles are based on healthy respect for the land and responsible farming, e.g the use of organic composting and straw mulching to eliminate need for herbicide sprays and the cultivation of inter-row cover crops to add soil nutrients. These principles flow through into the winery where minimal additions, wild yeast ferments and low intervention winemaking results in wines that are made with integrity and that are distinctively Bannockburn.
