In an article in Decanter, William Kelley's reports on his top Picks in California Cabernet. They're all really great wines, here's what he has to say about Foxglove:

Foxglove, Cabernet Sauvignon, Central Coast 2013 90
£15.50-£17 Bottle Apostle, Honest Grapes; Stannary St Wine Co, Uncorked, WoodWinters

Does California produce a better Cabernet for the price? This unpretentious bottling from the Central Coast is beautifully pure and expressive, bursting with clean raspberry fruit and nicely balanced on the palate. The US needs more wines like this. Drink 2016-2021 Alc 13.9%
