Oak
Aging in an oak barrel is a key step in
the production of great wines and spirits. The wood
is a true oenological tool. The barrel serves as
integrator - it preserves the characteristics of the
grape variety, the terroir, and the wine’s flavor,
all while harmonizing the elements for greater
complexity.
Oak helps to soften and subdue the
natural aggressive tannins of wine. The
tight-grained oak is porous, allowing for minute
amounts of evaporation and oxygenation. This
exchange between the outside air, the barrel and the
wine provide for rounding of tannins and developing
of aromatics. The end result is a wine of finesse.
French Oak
French Oak
brings a noble structure to wine, with elegance, preserving the fruit and aromas of the wine.
Seguin Moreau’s French oak is Haute Futaie, the tallest trees coming exclusively from forests regulated by the National Forests Office.
The forests are managed on the principle of annual regeneration, ensuring a consistent supply of sustainable wood.
Rigorous selection results in a contribution of aromatic components, a contribution of subtle yet structuring tannins that respect the fruit
and a steady oxidation of the wine, due to the grain’s texture, which balances the exchange with the outside atmosphere.
American Oak
Seguin Moreau uses oak from the tightest grain American white oak
which undergoes the same proactive maturation
process as French oak.
American oak provides a high level of aromatic complexity, which adds richness to the mid-palate of a wine and well-integrated toasty spice notes.
American oak aged for three years is also available. The extra year of aging softens the aromas further, resulting in more subtle and finessed flavours
.
Russian Oak
Caucasian oak develops the freshness and the aromatic nature of the grape variety. It brings tannins which help the structure of the wine and a tight and fine combination.
Its aromatic contribution is low in lactones. The wine presents a less intense woody character which is never excessive, with a more perceptible fruity flavor. It shines in elegant red wines that are sensitive to absorbing oak, such as Merlot or Pinot Noir
based wines.
Toast
The toasting phase is a key stage, mellowing wood’s harsh tannins and mitigating raw oak flavors.
Over time, Seguin Moreau came to differentiate between the firing of the barrel at the tightening stage and the oenological toasting of the barrel: bousinage. Bousinage dramatically changes the wood’s physiochemical composition and physical structure
by breaking down and caramelizing monosaccharoses
on the wood’s surface.
Tannins also go through a similar process. With enough heat, the tannins
can be completely destroyed. Hemicellulose begins to
release its basic sugar compounds, which contribute to
toasty aromas. Lignin breakdown leads to the creation of
vanillin, oak’s signature flavor, as well as
syringaldehyde. At higher temperatures, lignin creates
volatile phenols, such as guaiacol, lending smoke notes.
Grain
The use of superior growth, wood from 150- to 200-year-old forests ensures dense, tightly packed grain and fine tannins.
The French government’s tight control over the forests ensures trees are spaced properly, contributing to slow growth of trees with regular and fine grain.
Tighter-grained oak will release its wood compounds and tannins more slowly than semi-tight grain and medium-grained oak. As the grain gets tighter, the rate of evaporation slows down, as does the exchange between the wine and the outside air.
Seguin Moreau categorizes most barrels according to grain and its tightness.
The Icône
barrel, while customarily fine grain, is selected based
on its chemical composition of wood soluble compounds.
Shapes and Sizes
In addition to the traditional 225L Bordeaux and
228L Burgundy barrels available in various
configurations of stave thickness, degree of toast
and finish, Seguin Moreau offers numerous options:
265L American oak
300L American oak Hogshead
300L Haute Futaie French Oak
320L Muid’Oc
500L American oak or Haute Futaie French oak puncheon
600L Demi-Muid
600L Micro-Vinificator
400L Spirit Barrels
Large format barrels provide gentle treatment and extraction of the components of the vintage
and can be configured as normal sized barrels.
The Micro-Vinificator ensures a gentle vinification as it turns on its chassis so that its stainless steel paddles break the cap while protecting the berries. There is no pump, nor cooling system as the fermentation is longer than in stainless steel vats, and the temperatures are naturally stable. The anthocyanins fix themselves by combining with the ellagitannins of the wood and the micro-oxygenation is carried out by natural osmosis.
The oak used in spirits barrels has a wide grain
texture, and is rich in phenolic components that are
easily extractable and suit a slow and gradual
oxidation.
