Late autumn grapes on the vine at the Q Wine vineyard

Why We Wait to Pick

By Jules Matthews

By the time many New Zealand vineyards have finished harvesting, the grapes at Q can still be on the vines. In the Waitaki Valley, autumn is not necessarily the end of the growing season. Our latest harvest has been as late as 6 May, a date that surprises people who imagine picking happens at much the same time everywhere.

The Waitaki Valley sits between the Southern Alps and the eastern coast, with a long, relatively dry growing season and cool conditions that can extend ripening. That extra time is useful, but it comes with a trade-off. The grapes may be developing flavour slowly while the weather is becoming less predictable. Frost, rain and wind do not consult a harvest calendar.

People often ask whether grapes are ready when they reach a particular sugar level. Sugar is part of the answer, but it is not the whole answer. Acidity changes as grapes ripen, and flavour, tannin and texture can develop at different speeds. Pinot Noir skins and seeds, for example, tell a different story from a laboratory reading alone. The decision is about how those elements sit together. The numbers help, but tasting the fruit and understanding how the season has unfolded matter just as much.

That balance is especially important for the styles we make. Freshness is one of the pleasures of a cool-climate Chardonnay or Pinot Gris, but a wine also needs flavour and shape. Pinot Noir needs enough ripeness for its tannins and fruit to feel resolved, without losing the lift that makes it enjoyable at the table. Waiting another week might help. It might also be a week too long.

The final decision about when to pick rests with our winemaker, Antony Worch. He weighs the fruit, the weather ahead and what each part of the vineyard is showing him. Hand-harvesting lets us respond to those differences rather than imposing one date across every row. Our preference is to intervene as little as practical in the cellar, which makes getting the fruit right in the vineyard all the more important. The aim is not to manufacture a style after harvest, but to preserve the character the season and this land have given us.

When you open a bottle, you should not have to think about any of these decisions. You should simply find flavour, freshness and balance, with something recognisable about the Waitaki Valley in the wine. The work of picking at the right moment is to give that character its best chance.
