Ernst Storm and Gavin Chanin don’t actually make wine together – but you wouldn’t know it – at a recent London masterclass this hot duo from California’s Santa Barbara county seemed joined at the hip rather than come from rival wineries. What these friends share is a passion for old school Californian winemaking with minimal use of oak and sourcing prime fruit from some fantastic blocks in the Santa Maria and Santa Rita Hills. David Kermode tasted through their Chardonnay, Pinot Noir and Syrah and was knocked ‘sideways’ by the wines as well as learning a thing or two about their shared winemaking philosophy.
