Description Cool climate Aussie Chardonnay is in vogue, and this single vineyard Tumbarumba from Jason Brown, owner of the highly successful Moppity Vineyards in Hilltops, is a prime example. It boasts a Gold and 94pts. Delicious. As Coppabella’s website tells us: “Sirius is the brightest star in the constellation; a fitting name for our flagship wine. The best of the vineyard’s fruit is reserved, usually coming from our prized block, Block 20 exclusively for Sirius.'
