Ever Wonder About the Types of Oak Used in Wine Barrels?

Wine may be fermented and aged in a variety of materials including stainless steel, ceramic vessels, including concrete, and in oak barrels.

Oak barrels add additional quality, character and smoothness to wines and can impart many flavors into the wine. 

Barrels for wine-making are commonly made of French common oak (Quercus robur), white oak (Quercus petraea), and American white oak (Quercus alba)

Of the various species of oak, Quercus robur is said to provide a fuller body and larger tannin structures, giving less complexity and elegance than Quercus petraea. Forests in Hungary and France grow both species, including hybrids of the two. These two species are quite distinct from Quercus alba (American oak) in the flavors they impart.

Here’s a quick summary of the differences:

  • American Oak - Wine barrels made in the US are typically from White Oak that is grown in the east and mid-west. American oak is known for imparting sweeter flavors of vanilla, coconut, as well as dill and sweet spices.

  • Hungarian Oak - These barrels may be made from either the Quercus robur or Quercus petraea species. Quercus robur is said to provide a fuller body and larger tannin structures, giving less complexity and elegance than Quercus petraea. Hungarian oak barrels are known for imparting bolder, richer flavors of butterscotch, vanilla, clove, cinnamon, and toffee.

  • French Oak - French oak wine barrels are from the Quercus robur species but tend to have finer grains. The flavors imparted from French oak are said to be more subtle and include dark chocolate, roasted coffee beans and exotic, savory spices.

All of these imparted flavors can be dialed-up or down depending on the degree to which the barrels are ‘toasted.’ A winemaker will decide on what degree of toasting is appropriate for their wine’s style. Our 'job' as wine drinkers is simply to enjoy all the wonderful flavors that oak, and toasted oak, add to our wine. Cheers!

Wine Blends Are an Interesting Combination of Art and Science

In years past in the U.S., red wine blends were sold by the jug as "Red Wine" or "Table Wine."  These were inexpensive wines that were blends of grapes, vineyards or even vintages. So, blends are often discounted or disregarded as being of poorer quality.

But we only need to look to France, home of some of the world’s best wines, to see that blends are nothing to turn your nose up at.  France's famous region of Bordeaux produces red blends almost exclusively.  Depending on which bank the wine is from in Bordeaux, it will be a different blend. The Left Bank is known for its blends based on Cabernet Sauvignon while the Right Bank blends are Merlot based. These blends may also include Cabernet Franc, Petite Verdot and Malbec.

Other famous regions known for their blends include the Rhône Valley that uses Grenache, Syrah and Mouvedre and the so-called Super Tuscans from Italy that may include Merlot, Cabernet Sauvignon, Sangiovese, Syrah, Cabernet Franc and others.

The main reason that winemakers produce blends is to make the best wine possible. Blending different grape varieties is useful in accentuating a particular grape's virtues. The goal is to produce a wine that is actually better than the sum of its parts. And blending allows wines to be more well balanced and complex in their aromas, flavors, colors and textures. The blended grapes can add layers of flavor that will change through the process of taking the first sip, letting it sit on your tongue and then as you swallow.

In blending wine, amounts as small as 1% of a varietal can make a difference. It’s not unusual to find blends that contain only 1% or 2% of a given varietal. And, yes, just 1% can make a difference. You may not be able to detect that 1% directly, but the winemaker has added that amount to make an overall positive difference to the final product.

Some varietals commonly used in wine blending:

  • Barbera for its acidity which helps the mouthfeel and structure of the wine

  • Carignan for its aromatic notes and to produce greater robustness with its red and black fruit flavors and its peppery finish

  • Cabernet Franc for its floral notes as well as its red fruit and peppery flavors

  • Malbec for its soft tannin and floral aromas as well as its color and flavor intensity

  • Petit Verdot for its herbal notes, as well as it bold color, flavor and tannin

  • Viognier for its floral notes and added body in white blends and its aromatic complexity and soft tannin in red blends

So, don't turn up your nose at red wine blends or question that 1% of a given varietal.  These can actually be some of the best wines in the world. Cheers!

Your Oaked Wine May Have Never Been in an Oak Barrel!

Oak is used extensively in winemaking during fermentation and aging. It can add flavor compounds including aromas of vanilla, clove, smoke and coconut.

Oak barrels also allow the slow ingress of oxygen a process which makes wine taste smoother and less astringent.

Oak barrels also provide a great environment for certain reactions to occur, specifically Malolactic Conversion.

While oak wine barrels are made of French, American and Hungarian oak, they are all expensive. And they only impart flavor to wines during their first two to three uses, after which they are considered ‘neutral.’

So, to get the oak flavors without all the cost, some wines are made with oak chips, oak cubes, oak staves and even oak powder. Using these oak barrel alternatives allows wine makers to use less expensive containers (e.g., Stainless Steel tanks) and still get the desired oak flavors. After the wine has had the necessary time in contact with the chips, cubes, staves or powder, they are physically removed or filtered out and consumers never know the difference.

This may seem ‘wrong’ to many wine purists, but it is allowing winemakers to produce oak flavors in their wines at considerably lower costs. And, studies have been done that show consumers can’t tell the difference. Wine labels don’t tell us the difference, but if oak alternatives are used, and you enjoy the wine, then I’d say the winemaker succeeded! Cheers!

Ever Wonder How Rosé Wine is Made?

There seems to be a lot of information and some misinformation out there about the production of rosé wine. I'm not sure why this topic is so complicated or confusing. Rosé is quite simple and such a simple pleasure. So, let's take a look at how rosé is made.

Rosé is made from red wine grapes.  But, it's made in the traditional white winemaking process. Hence the confusion.  So, first, realize that all juice from wine grapes, whether from red grapes or white grape, is nearly clear. And, all the color in a finished wine comes from the skin of the grapes, not from the juice.

So, with that in mind, rosé wines are made in one of the following ways:

  • Maceration -- This process is the most common method used in the production of rosé wines. The word 'Maceration' literally means to soften by soaking. And in the case of wine production, it means to allow the grape skins to soak in the grape's juice. With red wine, the juice spends a lot of time (days to weeks) soaking with the grape's dark purple skin that gives red wine its deep color.  In the production of white wines, maceration is avoided. But for rosé, the red wine grape skins spend some limited time soaking with the juice, but not to the extent of red wine production. As a matter of fact, the juice gets very little time in contact with the grape skins. Usually a matter of 2 to 24 hours.  Once the winemaker achieves the desired color they are looking for, the juice is separated from the grape skins and allowed to ferment in a separate tank. For rosé, this is typically a stainless steel tank that is chilled in order to maintain the freshness of the juice.

  • Saignèe ("San-yay") -- While somewhat similar to maceration, this method allows the grapes to be crushed under their own weight and the 'free run' juice is collected.  Since this juice spends little time in contact with the red grape skins, the resulting color is light pink.  Some argue that this is the highest quality rosé because it is the most pure.  Others consider this just a bi-product of red wine production since the remaining grapes and juice go on to become a more highly concentrated red wine.  Regardless, the rosé juice yielded from this process is separated, fermented in stainless steel tanks and kept at cool temperatures to preserve its freshness.

  • Blending -- While this is a process that yields pink wine, it is highly frowned upon and outlawed in France and several other countries.  This method uses mostly white wine that is blended with just a touch of red wine, resulting in a pink wine.  This method is certainly not used in most rosés.

Regardless of the method used, rosés can be dry or sweet. As previously mentioned, one key to finding a dry rosé is the alcohol level. But, rosés can also vary by grape type:

  • Dry Rosés -- Below are listed some of the most common dry rosé wine varieties, used alone or in a blend:

    • Grenache, Sangiovese, Syrah, Mouvedre, Carignan, Cinsault, Pinot Noir

  • Sweet Rosés -- Like any wine, rosé wine can be made sweet by not fermenting all the natural sugar in the grape juice to alcohol. So, if you are looking for a sweet rosé, these are typical examples:

    • White Zinfandel, White Merlot, Pink Moscato

Always remember with rosé wines that they should be enjoyed young (within two years of its vintage) while they still have their bright fruit flavors and crisp acidity, and they should be served well chilled.

One way or the other, give rosé wines a try. Cheers!

Ever Wonder? How are Non-Alcoholic Wines Made and are they Good?

Non-alcoholic wines have been around for years. But, you may have wondered:

  • What exactly is non-alcoholic wine?”

  • How is it made?”

  • Is it any good?”

First, let’s look at non-alcoholic wine. It actually is ‘real’ wine that’s been made from fermented grapes. It can have similar flavors to wine, just without the alcohol. Although, non-alcoholic wine may still contain a very small amount of alcohol. So, check the label - it will tell you the exact amount of alcohol that it contains.

Now, let’s take a brief look at how non-alcoholic wine made. As stated previously, it starts with "‘real’ wine made from fermented grapes. Then it goes through one of two processes to remove the alcohol. One method is called vacuum distillation where the wine is heated to temperatures where the alcohol begins to evaporate. This temperature is below the boiling point of the wine but, because the boiling point of alcohol is lower than water, the alcohol ‘boils’ off and is pulled away in a vacuum chamber.

The other method is reverse osmosis. This process uses an extremely fine filter that only allows the water and the alcohol to pass through. The filter catches all the fine grape particles that give the wine its color, its tannin and its flavors. The mixture of water and alcohol is then distilled to remove the alcohol. The left-over water is then recombined with the grape solids to form a non-alcoholic wine.

The same processes are used for “low calorie” or low-alcohol wines except they don’t remove all the alcohol.

Now, there’s the final question “Is non-alcoholic wine any good?” And, as you might have guessed, it’s not as good as “real” wine but it does have a lot of similarities. We’ll discuss this a bit more next time. Until then, Cheers!
