Barrel Size

Barrel Size – Does it affect aging time?

Posted on by Nigel

The size of the barrel can have a significant impact on the aging process of a wine or spirit. Smaller barrels such as 1.5L or 10L barrels have a greater surface area to liquid ratio than larger barrels such as the common 225L barrels. This results in a faster infusion of the wood’s flavours and characteristics into the liquid. As a result, smaller barrels can age a wine or spirit in a shorter period of time, typically 6-12 months, while larger barrels may take up to 2-3 years.

It is also important to note that the size of the barrel affects the amount of oxygen that comes into contact with the liquid, as well as the temperature of the liquid. Smaller barrels have a larger ratio of surface area to liquid volume, which means that there is a greater presence of oxygen in the barrel. This can accelerate the aging process by promoting chemical reactions in the wine or spirit. In addition, the temperature inside a smaller barrel can fluctuate more frequently due to its smaller size.

On the other hand, larger barrels have a smaller ratio of surface area to liquid volume, which means that there is less oxygen present in the barrel. This can slow down the aging process and result in a more gradual infusion of the flavours of the wood. Additionally, the temperature inside a larger barrel can be more stable.

The difference between French and American Oak

Posted on by Nigel
There are two predominant species of oak used for making barrels – French (or European) white oak, Quercus petrea, and American white oak, Quercus alba. Their differences are subtle but distinct. French oak and American oak are both commonly used to age wine and spirits, but there are some key differences between the two types of wood.

First and foremost, the flavour profile imparted by the wood is different. French oak is known for imparting a more delicate and nuanced flavour profile to the wine or spirit aged in them, with notes of spice and vanilla. On the other hand, American oak tends to impart a more bold and pronounced flavour profile, with notes of coconut and dill. This difference in flavour profile is due in part to the tannins and other compounds found in the wood. French oak has a higher concentration of “vanillins” which are responsible for the vanilla notes, while American oak has a higher concentration of “lactones” which are responsible for the coconut notes.

Another important difference between the two types of wood is the porosity and the tightness of the grain. French oak is known to be tighter grained and tends to be less porous, which can result in slower aging. This can be beneficial for premium wines or spirits that are intended to be aged for a longer period, as the flavours of the wood will be imparted gradually over time, allowing the wine to develop a more complex and nuanced flavour profile. On the other hand, American oak is known to be more porous which can result in faster aging. This can be beneficial for full-bodied wines and spirits that are intended to be aged for a shorter period, as the flavours of the wood will be imparted more quickly, allowing the wine or spirit to develop a more rich and robust flavour profile.

The geographical origin of the oak also plays a role in the final flavour profile of the wine or spirit. French oak is mainly grown in the center and south of France, and the oak grown in different regions imparts different flavour notes to the wine or spirit. American oak is mainly grown in the United States, particularly in the Ozark Mountains and the Appalachian Mountains. The oak grown in different regions of the US also imparts different flavour notes to the wine or spirit.

In terms of the types of wine and spirits aged in each type of oak barrel, French oak barrels are often used to age high-end wines such as Burgundy, Bordeaux and some Champagne, as well as premium spirits like Cognac and Armagnac. American oak barrels, on the other hand, are often used to age bold and full-bodied wines such as California Cabernet Sauvignon, Zinfandel and some Australian Shiraz, as well as some premium spirits like bourbon, whiskey and rum.

In conclusion, the choice between French oak and American oak barrels for aging wine and spirits will depend on the desired flavour profile and aging time. French oak barrels impart a more delicate and nuanced flavour profile while American oak barrels impart a more bold and pronounced flavour profile. French oak barrels also result in slower aging, while American oak barrels result in faster aging. French oak barrels are mainly used for high-end wine, while American oak barrels are mainly used for full-bodied wine and some premium spirits.

What type of Wine or Spirits are aged in French Oak Barrels vs American Oak Barrels

Posted on by Nigel

French oak barrels are often used to age high-end wines such as Burgundy, Bordeaux and some Champagne, as well as premium spirits like Cognac and Armagnac. The tight grain of French oak allows the wine or spirit to age slowly, with the flavours of the wood being imparted gradually over time. The delicate and nuanced flavours imparted by French oak also complement the complex and subtle flavours of these premium beverages.

On the other hand, American oak barrels are often used to age bold and full-bodied wines such as California Cabernet Sauvignon, Zinfandel and some Australian Shiraz, as well as some premium spirits like bourbon and whiskey. The more porous nature of American oak allows the wine or spirit to age faster, with the flavours of the wood being imparted more quickly. The bold and pronounced flavours imparted by American oak also complement the rich and robust flavours of these full-bodied beverages.

New Oak Vs Recycled Oak Barrels

Posted on by Nigel

The main difference between a barrel made from new oak and a barrel made from recycled oak is the number of times the barrel has been used. New oak barrels are made from freshly cut oak and have not been used to age any wine or spirit before. Recycled oak barrels, on the other hand, have been used at least once to age a wine or spirit and have been reconditioned for reuse. The recycled oak barrels impart not only the flavour and characteristics of the oak but also the flavour of the previously stored wine or spirit.

New oak barrels are generally considered to be more expensive than recycled oak barrels, as they require more labor and resources to produce. The wood is also more likely to be more dense and tight-grained in new oak barrels, which can affect the rate of aging and the flavour profile imparted to the wine or spirit. New oak barrels will impart more robust and pronounced flavours to the wine or spirit it is aging than a recycled oak barrel would.

Recycled oak barrels have already imparted some of their flavour and characteristics to the wine or spirit that was previously aged in them, and thus will tend to impart a more subtle and nuanced flavour profile to the wine or spirit it is aging now. These barrels can also impart some of the flavour of the previously stored wine or spirit. Recycled oak barrels can also have a more porous structure, which can result in faster aging.

The choice of using a new or recycled oak barrel depends on the desired flavour profile, and the price point of the distillers. Premium wines or spirits may be aged in new oak barrels to impart more pronounced and robust flavours, while other wines or spirits may use recycled barrels to impart more nuanced and subtle flavours and to gain some of the previously stored wine or spirit flavour.

French Oak or American Oak for Aging Port

Posted on by Nigel

Both French oak and American oak can be used to age port, however, the choice of oak will affect the final flavour profile of the port.

French oak is known for imparting delicate and nuanced flavours such as vanilla and spice. These flavours complement the fruit-forward and complex flavours of port, and can add a level of complexity to the wine. French oak is also known for being less porous, which can result in slower aging, which can be beneficial for ports that are intended to be aged for a longer period.

American oak, on the other hand, is known for imparting bold and pronounced flavours such as coconut and dill. These flavours can complement the rich and robust flavours of port, and can add a level of depth and intensity to the wine. American oak is also known for being more porous, which can result in faster aging, which can be beneficial for ports that are intended to be aged for a shorter period.

Overall, the choice between French oak or American oak for aging port will depend on the desired flavour profile and aging time. Some producers may prefer to use French oak for aging their ports for a longer period to achieve a more complex and nuanced flavour profile, while others may prefer to use American oak for aging their ports for a shorter period to achieve a more rich and robust flavour profile.

Charring and Toasting

Oak Barrel Char and Toast levels

Posted on by Nigel

Oak barrel charring and toasting are two different processes that are used to prepare oak barrels for aging wine and spirits. Both processes serve to soften the tannins in the wood and to add flavour compounds to the liquid that will be aged in the barrel.

Charring is the process of burning the inside of the barrel with an open flame. This process creates a layer of charcoal on the inside of the barrel, which acts as a filter to remove harsh tannins and imparts flavours like smoky, toasted and vanilla notes. The level of charring can vary and is usually classified into levels such as light, medium and heavy char. A light char will result in a softer, more delicate flavour profile, while a heavy char will result in a bolder, more pronounced flavour profile. Charring is mainly used in the production of spirits like bourbon, scotch and whiskey.

Toasting, on the other hand, is the process of heating the inside of the barrel with a controlled flame. This process also softens the tannins in the wood and imparts flavours like vanilla, caramel, and spices. The level of toasting can vary and is usually classified into levels such as light, medium and heavy toast. A light toast will result in a softer, more delicate flavour profile, while a heavy toast will result in a bolder, more pronounced flavour profile. Toasting is mainly used in the production of wine, particularly red wine.

The main difference between the two processes is the level of charring and toasting and the type of final product that the oak barrel is used for. Charring is mainly used for spirits, while toasting is mainly used for wine.
