98-Point by Jancis Robinson.
Practicing Biodynamic
Made entirely from estate fruit and biodynamically farmed. This is a block-specific bottling from a portion of the vineyard that has consistently shown a strong, recognisable signature since its founding, 28% whole cluster & 30% new oak with 16 months' ageing. 
This is the most overtly, typically California Pinot in the Hirsch line up. With the other cuvées I would smell the wine and be hit by a range of aromatics and be intrigued by that distinctive note. With the Block 8 I put my nose in the glass and immediately thought, oh that smells exactly of California Pinot. It is perhaps less complex or nuanced than the other block-specific wines from Hirsch, but it is also exactly what we want from California Pinot Noir – there is plenty of tannin but not too much, the wine focuses on red fruit with an accent of cola, forest notes denote the region, and a sprinkle of spice tells a bit of the ageing regime. Most of all it is pleasantly textural, lengthy and mouth-watering – a pleasing California Pinot.
