Study Notes
Harvest
- Harvest marks the end of grape ripening and effects wine quality, dependent on harvest parameters, logistics, legislation and costs
Choosing the Date of Harvest
- Traditionally harvest was 100 days post-flowering
- Harvesting at 9.5–11% abv in cool regions is common, like Petit Chablis (9.5%), Chablis (10%), and Bourgogne Blanc (10.5%)
- Modern harvest timing focuses on aroma, tannin ripeness, and weather conditions
- Warmer climates and better viticulture also affect harvest dates, allowing for better ripening
- Potential alcohol is the amount of alcohol produced when fermenting grape must
- Alcohol levels can be adjusted upwards via chaptalisation
- Grape growers make choices about harvesting date in relation to particular wine styles
- Rain near harvest can cause grape dilution, splitting, and rot, often forcing an early harvest
- Extended hang time is debated, with some arguing it enhances ripeness, while others caution it can lead to unbalanced wines
Harvest Dates for Wine Styles
- Chenin Blanc in the Loire Valley sees harvest dates vary over 4-6 weeks, including early for sparkling wine, mid for dry or off-dry wine, and late for botrytised or sweet wine
- Zinfandel harvest can be early to mid-August for white Zinfandel or later in September for red Zinfandel, and exhibits common uneven ripeness within bunches
- Harvest timing affects wine style, for example early for sparkling wines and late for botrytised or sweet wines
Ripeness Factors
- Sugar levels are measured in Brix, and dry still wines get harvested between 19° and 25° Brix (11–15% abv)
- Acidity is assessed via titration and pH
- Aroma and tannin evaluations are performed
High-Tech Tools
- Infrared spectroscopy or similar tools can provide readings but do not replace tasting
Botrytised and Late Harvest Wines
- Multiple passes picked in specific conditions are needed, like Eiswein at -8°C / 18°F
Machine Harvesting
- Machine harvesting is favored for large-scale, inexpensive to mid-range wines in vineyards suited for mechanization (flat, evenly spaced)
- California studies show machine harvesting to be one-third the price of hand-harvesting
- Modern harvesters use bow-rod shakers and even optical sorting
- Some harvesters can add SOâ‚‚ to reduce oxidation
- Advantages include being fast, cheaper, reducing labor reliance, and enabling night harvest to keep grapes cooler (up to 15°C / 59°F) for microbial control
- Disadvantages include being less gentle, unsuitable for whole bunch styles, expensive for small producers, and unable to handle uneven or steep vineyards
- Machine harvesters shake grapes from the stem, unsuitable for whole bunch requirements
Hand Harvesting
- Hand harvesting is preferred for premium wines and when selective picking is essential, using secateurs
- It is necessary for wine styles using whole bunches, such as traditional method sparkling wines, Champagne, bottle-fermented sparkling wines, and carbonic maceration like Beaujolais
- It is also needed for botrytised wines requiring selective picking, steep slopes, and bush vines
- Advantages include gentle handling, better handling of uneven or steep vineyards, and the ability to select bunch-by-bunch
- Handled carefully while using small, stackable crates of 10–15 kilos avoids crushing, oxidation and microbial spoilage
- Disadvantages include being labor-intensive, more costly, and limited to daylight unless night tools are used
