Transfer Method Sparkling Wine
Bottle-fermented complexity without the riddling rack: the transfer method bridges artisan quality and production efficiency in one elegant step.
The transfer method begins identically to the traditional method, with secondary fermentation and lees aging in individual bottles. Rather than riddling and disgorgement, the aged wine is transferred under counter-pressure into a sealed tank, filtered, dosed, and rebottled. The result is a bottle-fermented sparkling wine of genuine autolytic complexity, produced more efficiently and with greater batch consistency.
- Developed in the 1940s as a practical alternative to costly manual riddling, the transfer method retains the quality advantages of bottle fermentation while bypassing the disgorgement step
- EU and international labeling rules distinguish transfer method wines clearly: labels read 'fermented in bottle,' while traditional method wines state 'fermented in this bottle'
- A minimum of 6 months on lees in bottle is required to use the 'bottle fermented' designation; the EU minimum for quality bottle-fermented sparkling wines is 9 months on lees
- Champagne houses regularly use the transfer method (known as transversage) for non-standard bottle formats smaller than 375ml and larger than 1.5 litres, which cannot practically be riddled
- Sparkling wines from Australia and New Zealand frequently use the transfer method, making it a defining technique of the New World sparkling wine landscape
- The transfer method also reduces bottle-to-bottle variation inherent in traditional method production, since wines from many individual bottles are homogenised in the pressurised tank before rebottling
- The vast majority of German Sekt is produced by the Charmat (tank) method rather than the transfer method; traditional bottle-fermented Sekt accounts for only about 1.7% of Germany's total sparkling production
What It Is
The transfer method is a sparkling winemaking technique in which base wine undergoes secondary fermentation and lees aging in individual bottles, exactly as in the traditional method. The key difference comes at the end of aging: instead of riddling each bottle and disgorging individually, the wine is transferred under counter-pressure into a sealed, pressurised tank. There, it is filtered to remove yeast sediment, dosed if desired, and rebottled under inert gas. The wine qualifies as bottle-fermented and may carry that designation on the label, but because it is not disgorged from the original bottle, it cannot claim 'fermented in this bottle,' which is reserved for the traditional method.
- Secondary fermentation occurs in individual bottles, identical to the traditional method
- Transfer to a pressurised tank replaces riddling and disgorgement
- Labels correctly read 'fermented in bottle,' not 'fermented in this bottle'
- Dosage can be adjusted after filtration, allowing precise sweetness calibration before final bottling
How It Works
The process begins with blending base wines and adding the liqueur de tirage, a mixture of wine, sugar, and yeast that triggers the secondary fermentation in sealed bottles. The bottles are laid horizontally in temperature-controlled cellars while fermentation produces CO2, building pressure of up to 5 to 6 bar inside each bottle. The wine then rests on its lees for the desired aging period. When ready, the bottles are chilled to stabilise the CO2, then emptied under counter-pressure into a sealed pressurised tank. The wine is filtered to remove yeast solids, the liqueur de dosage is added to set the final sweetness level, and the finished wine is rebottled immediately under an inert gas blanket to prevent carbonation loss.
- Liqueur de tirage: yeast and sugar addition to base wine to trigger secondary fermentation in bottle
- Bottle pressure during and after secondary fermentation reaches approximately 5 to 6 bar
- Transfer under counter-pressure ensures CO2 is not lost during the tank filtration step
- Final bottling takes place under inert gas, preserving carbonation and freshness
Effect on Wine Style
Because secondary fermentation and lees contact occur in bottle, transfer method wines develop the same autolytic character associated with the traditional method: the breakdown of spent yeast cells over time contributes bread dough, brioche, biscuit, and nutty notes that distinguish bottle-fermented wines from tank-method styles. The minimum six months on lees required for the 'bottle fermented' designation builds meaningful complexity, and producers who age their wine for 12 months or more before transfer can achieve profiles very close to traditionally disgorged wines. The homogenisation that occurs when many bottles are pooled in the tank can produce greater batch consistency than traditional method, though some argue the finest traditional method wines, with their long undisturbed bottle aging, retain a depth of tertiary development that is difficult to replicate.
- Yeast autolysis during bottle aging contributes brioche, biscuit, and toasted bread complexity
- Minimum 6 months lees contact in bottle required for the 'bottle fermented' label claim
- Pooling multiple bottles in the tank reduces bottle-to-bottle variation common in traditional method
- Fresh fruit character is better preserved than in equivalent traditional method wines due to shorter total production cycles
Where and Why Winemakers Use It
The transfer method is particularly common in Australia and New Zealand, where it has become a defining approach for producing high-quality sparkling wines at commercial volumes. In Champagne, the method is used practically rather than stylistically: for the non-standard bottle sizes that cannot be riddled in gyropalettes or on pupitres, including piccolo bottles and large formats above the standard magnum. Producers elsewhere choose the transfer method when they seek the quality markers of bottle fermentation without the capital investment and labour costs associated with riddling and disgorgement infrastructure. It is especially suited to volume producers who also value the consistency benefits of tank blending.
- Australia and New Zealand are the heartland of the transfer method for commercial sparkling production
- Champagne houses use the transfer method (transversage) for non-standard bottle formats that cannot be riddled
- Well-suited to producers making large batches who prize consistency alongside bottle-fermented complexity
- Avoids the need for riddling infrastructure, reducing both capital costs and skilled labour requirements
Notable Examples and Producers
Lindauer, New Zealand's leading sparkling wine brand, was created by Montana Wines from the 1980 harvest and released in 1981 as the country's first commercially available bottle-fermented sparkling wine. Now owned by Lion, Lindauer Brut Cuvee is a Chardonnay and Pinot Noir blend that undergoes approximately 12 months of lees contact before transfer, and has won awards at competitions including the New Zealand International Wine Show and the Sydney International Wine Competition. Yalumba, Australia's oldest family-owned winery, founded in 1849 in the Barossa Valley, has a long history of sparkling wine production alongside its renowned still wines. In Germany, major volume Sekt brands including Henkell use the tank (Charmat) method rather than the transfer method, while quality-focused producers pursuing bottle-fermented Sekt use either the traditional method or transfer.

- Lindauer was first produced by Montana Wines from the 1980 harvest and released in 1981, acquired by Lion from Pernod Ricard in 2010
- Champagne houses use transversage (a transfer method variant) for piccolo and large-format bottles that cannot undergo riddling
- Australian producers have adopted the transfer method as a cost-effective route to bottle-fermented complexity at commercial scale
Transfer vs. Traditional vs. Charmat Method
The transfer method occupies a clear middle ground between the traditional method and the Charmat (tank) method. Like the traditional method, it involves secondary fermentation and lees aging in individual bottles, producing autolytic complexity. Unlike the traditional method, it bypasses riddling and disgorgement, which reduces labour costs and production time while still permitting the 'bottle fermented' label designation. The Charmat method, by contrast, conducts secondary fermentation in pressurised tanks rather than bottles, typically over a matter of weeks, producing wines with fresh primary fruit character but minimal autolytic complexity. Charmat is the dominant method for Prosecco and for the vast majority of German Sekt. Transfer sits closest to traditional method in sensory outcome, with the key practical trade-off being efficiency versus the finest nuances of prolonged undisturbed bottle aging.
- Traditional method: bottle fermentation, riddling, disgorgement from the same bottle; label reads 'fermented in this bottle'
- Transfer method: bottle fermentation and lees aging, then transfer to tank for filtration and rebottling; label reads 'fermented in bottle'
- Charmat method: secondary fermentation in pressurised tank over weeks; no bottle aging; prioritises fresh fruit over autolytic character
- German Sekt is predominantly Charmat-method; traditional bottle-fermented Sekt accounts for around 1.7% of total German sparkling production
Transfer method sparkling wines show the hallmarks of bottle fermentation: fine, persistent bubbles and a palate texture enriched by lees contact. With six or more months on yeast, expect biscuit, bread dough, and subtle toasted hazelnut notes layered over the primary fruit character of the base wine. Chardonnay-dominant cuvees lean toward citrus, green apple, and creamy brioche, while Pinot Noir adds red berry fruit and structure. Extended lees aging before transfer deepens autolytic complexity toward honey, dried fruit, and nougat. Acidity is typically bright and refreshing, providing balance to the creamy texture, and the finish is clean and persistent.
