Before discovering Starward's latest release, the Botrytis Cask, I had never heard of Botrytis wine. A conversation with Martin revealed it's a type of dessert wine, piquing my interest to learn a bit more about this wine. Some reading into Botrytis wine unveiled fascinating details about this unique wine and how it influences Starward's new project release.
Botrytis is a type of fungus that shrivels and decays wine grapes (see below for an image of the fungus on a bunch of riesling grapes), yet is highly coveted in winemaking due to its ability to intensify sweetness and add flavour complexity. Known scientifically as Botrytis cinerea, this fungus is related to the strains used in penicillin and blue cheese. In winemaking, Botrytis dehydrates the grapes, concentrating their sugars and flavours, which makes the resulting wine richer and sweeter. This process, often referred to as 'noble rot,' creates dessert wines with unique notes of honey, beeswax, and ginger. Notable examples include France's Sauternes and Hungary's Tokaji Aszú."
Typically harvested late in the season, Botrytis wines undergo a meticulous, slow fermentation process and can age gracefully for decades. Their rarity and labour-intensive production often make them expensive and highly sought after as the grapes are often hand picked to ensure there is a balance between botrytis fruit amongst the grapes.
Now what happens when you age whisky in Botrytis wine casks? I gather that the whisky will impart the characteristics from the Botrytis wine; with added sweetness, complexity, and a perhaps a rich, multidimensional whisky.
So this is exactly what Starward have done in their latest unveiling, the Starward Botrytis Cask, a single malt whisky, fully matured for seven years in fresh and charred casks that once held Botrytis Semillon dessert wine. It was first filled in 2017 and bottled this year. As Head Blender at Starward Jarrad Huckshold explained, he had to use both, fresh and charred Botrytis casks when creating this release The combination of two barrel finishes helped the liquid “develop the distinct dessert-like characteristics”. Jarrad added: “The fresh barrels impart those nuanced botrytis characteristics on our signature spirit; while the portion of casks that were charred offer a slightly savoury mouthfeel and balance out some of the dessert-like characteristics. This is a moreish whisky that will make an impression.”
It is said that Botrytis casks are uncommon as they're only made in small quantities in Australia, making this release exceptionally rare for Starward. In Australia, Botrytis semillon is a notable example of this style, produced from semillon grapes affected by Botrytis cinerea. The Hunter Valley is particularly famous for its Botrytis semillon, where the warm and humid climate, morning fog, and cooler evenings create perfect conditions for the development of 'noble rot'. The Hungerford Hill Botrytis Semillon is one example, with notes of sweet apricots and marmalade, balanced with some lemon citrus, balancing the richness and finishing clean.

Starward Botrytis Cask (48% ABV, Port Melbourne, Victoria, Australia, A$169)
The Starward Botrytis Cask, a single malt whisky, fully matured for seven years in fresh and charred casks that once held Botrytis Semillon dessert wine. Overall, it was a concoction of dessert flavours, almost resembling what I would call a Christmas whisky with the range of sweet, rich and delectable notes.
Nose: The nose opens with a rich aroma of wax honey, reminiscent of honeycomb, followed by a refreshing hint of peppermint, the smell of a lush winter morning. There’s a delectable scent of scrumptious Christmas cake, laden with dried fruits and spices, accompanied by a sweet cherry glaze. Notes of rum and raisin ice cream add a creamy, boozy undertone, while fresh apples and pears, and a medley of fruit salad, bring a lively, juicy character. Hints of burnt orange and cinnamon round out the nose, adding warmth and complexity.
Palate: On the palate, it is rich and indulgent, starting with the sweet, comforting taste of vanilla cupcakes. More of those succulent raisins and fruit bread come through, complemented by the flavour of rum-soaked bread, echoing the notes of a traditional Christmas cake from the nose that's packed with raisins. Cinnamon buns add a spicy sweetness. The chewy texture of caramel lollies adds a luscious, lasting sweetness, creating a beautifully balanced and layered experience.
Finish: The finish is exceptionally long. Glazed cherry remnants provide a sweet, fruity finish, with persistent notes of rum and raisin that carry through to the end. A subtle hint of mint gradually settles, offering a refreshing, clean conclusion.
Rating (on my very non-scientific scale): 93/100 (Hendy)
