Harvest

The UK harvest window

UK harvest usually starts in late September with the early-ripening varieties, often Pinot Noir and Pinot Meunier for sparkling base wine, and continues through October with Chardonnay, Bacchus, Seyval Blanc and the later-ripening reds. The exact timing is decided by sampling, with the winemaker tracking sugar, acid and flavour in the lead-up.

In a warm vintage like 2018, 2020 or 2025, harvest may start in mid-September and finish in mid-October. In a cool vintage like 2011, 2012 or 2021, harvest may run from late September through to early November, with the late-ripening reds sometimes not making it at all. The variation is one of the most challenging features of the UK climate.

Picking by hand or by machine

Most premium English grapes are still picked by hand. Hand-picking is gentle, allows the pickers to discard rotten or unripe bunches, and works well on the relatively small plantings that dominate the UK. A team of 20 to 30 pickers can bring in 10 to 15 tonnes a day from a well-organised vineyard, which is enough for a small winery.

Machine harvesting is gaining ground on the larger UK estates. Modern grape harvesters, straddle-type machines that roll over the trellis and shake the berries off, are gentler than their reputation suggests. They can pick 1 to 2 hectares an hour, which is a huge productivity gain. Several English producers, including Nyetimber and Chapel Down, have invested in their own machines.

The logistics of harvest

Once the decision to pick is made, the clock starts. Picked grapes need to get to the winery quickly, ideally within an hour or two, and they need to be kept cool in transit. A 10-tonne harvest from a single block will fill a small fleet of 1-tonne grape bins, each of which needs to be loaded onto a flatbed truck, driven to the winery, unloaded and tipped into the press or the fermenter.

For sparkling base wine, the press is the bottleneck. A modern pneumatic press can process 4 to 6 tonnes per cycle, taking 2 to 3 hours per load. For red wine, the bottleneck is the fermenter capacity. UK producers plan harvest logistics months in advance, with spare bins, refrigerated trucks and, increasingly, mobile pressing services that come to the vineyard.

The UK vintage calendar

For the consumer, the UK vintage calendar runs from harvest through to release. Still wines are typically released the spring or summer after harvest, around 9 to 12 months later. Sparkling wines are released 24 to 48 months after harvest for the entry tier, 36 to 60 months for vintage cuvées, and 60 to 84 months for prestige cuvées. The longer the lees ageing, the more complex the wine.

WineGB and the UK Vineyards Guide publish annual vintage reports, which are useful for tracking the year-on-year variation. The 2018, 2020, 2022 and 2025 vintages are all considered excellent, with high ripeness, good acidity and clean fruit. 2011, 2012 and 2021 are generally considered more challenging, with lower yields and lighter wines.
