Burton Union
A Burton Union is a connected set of horizontal wooden beer casks, swan-neck pipes and shared troughs. Fermentation lifts yeast-rich foam into the trough; beer drains back to the casks, leaving yeast behind.

A large, transparent, spherical borosilicate-glass vat designed for modern wine fermentation and maturation. The 220-litre Wineglobe model has a wide neck, fitted lid and support; its use and fittings vary by model.

The large glass wine globe is a modern cellar vat: a transparent spherical vessel with a short broad neck, fitted closure and a cradle or stand that carries the vessel rather than leaving it unsupported on its curved wall. It belongs to the glass-vessel family, but its industrial scale and cellar fittings distinguish it from a small demijohn used to hold a few litres. Famille Paetzold dates the Wineglobe’s creation to 2015; Decanter says the project followed a 2014 request from Burgundy winemaker Arnaud Ente and that the family produced its globes in Bordeaux from 2015. This dates this named modern vat, not the first use of glass in winemaking.
The manufacturer’s specification gives its 220-litre model a capacity of 220 litres at the brim, a height of 920 millimetres, a diameter of 750 millimetres and a 300-millimetre neck opening. The listed glass is 7 millimetres thick and the empty vessel weighs 33.8 kilograms. These figures describe this model; the same product line also includes other sizes, so they should not be applied to every glass globe. The photographed vessel has a fitted metal lid and bubbler. The appropriate stand, closure and handling equipment depend on the selected model and whether it is empty or full.
Famille Paetzold recommends its Wineglobe for fermenting and ageing white and rosé wines and for ageing red wines. The manufacturer says it has not yet developed equipment to make red-wine fermentation solids easier to run off, a practical limit when the vessel contains skins and other solids. Its FAQ describes a full-to-the-brim fill, with a lid, bung and bubbler that regulates variations in pressure. The maker explicitly warns that the bubbler must be correctly filled to avoid excessive pressure and a possible explosion. Decanter documents a Wineglobe at Hambledon Wine Estate in Hampshire, showing the contemporary vessel in a working winery.
Borosilicate glass forms a smooth, transparent wall. Unlike wood, glass contributes no wood-derived flavour and has very low porosity; the closure and fittings remain part of the vessel system, so “airtight” should not be inferred from the wall alone. The maker presents that near-impermeability and visibility as reasons to use glass for maturation and to observe lees sedimentation and wine clarity. These are manufacturer explanations, not proof that every wine benefits from the same vessel. Transparency also means cellar light needs attention: the maker advises working away from natural light and offers covers. Its care instructions caution against abrasive pads or unprotected tools that could scratch glass, and recommend removing the lid for washing. Use the exact maker’s handling and cleaning directions for the chosen globe and stand.
Famille Paetzold dates the Wineglobe's creation to 2015. Decanter reports that Burgundy winemaker Arnaud Ente requested a large glass vessel in 2014 and that the Paetzold family produced Wineglobes in Bordeaux from 2015. This is a modern vat design; it is distinct from much smaller glass demijohns and historic glass bottles.
The manufacturer warns that an improperly filled bubbler can allow excessive pressure and a possible explosion.
Hazard sourceThe filled globe requires a maker-specified stand for forklift movement; the empty 220-litre model alone weighs 33.8 kg.
Hazard sourceKeep the bubbler filled as directed by the manufacturer and use the model-specific closure.
Control sourceUse the manufacturer’s specified support and handling method when the vessel is full; avoid abrasive cleaning tools that can scratch the glass.
Control sourceDecanter reports the Paetzold family's Wineglobes have been produced in Bordeaux from 2015; the maker records the product's 2015 creation.
Decanter's caption identifies a Wineglobe in use at Hambledon Wine Estate in Hampshire; this is an example of use, not the origin of the vessel.

Wineglobe / Famille PaetzoldMaterial · Maker's design rationale
Why glass?The manufacturer identifies borosilicate glass and describes the vessel as smooth and non-porous.
The maker presents glass transparency and low porosity as enabling observation and low wall-mediated exchange; these are manufacturer claims.
