Deconstructing Llicorella

PrioratThis morning I set about to research the wine region of Priorat for a blog post.  I already knew the basics of the region, such as the fact that it is one of Spain’s two DOCa wines, the main grape variety is Garnacha Tinta, and the area came to international attention in the 1990s.

Wikipedia (I know, not the best reference but in this case, just a starting point) also had this to say, “The area is characterized by its unique terroir of black slate and quartz soil known locally as Llicorella.” I already knew that the soil in Priorat is mainly Llicorella…at least I knew the word, and could have guessed it correctly on a multiple choice test.  But being in a Monday sort of contemplative mood, I wondered if I really understood Llicorella.  Of course, I didn’t. So I set about to deconstruct Llicorella.

First of all…just what exactly is slate? Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from sedimentary rock composed of clay or volcanic ash. It is the finest grained foliated metamorphic rock.

Slate…a Metamorphic Rock

Metamorphic Rock? Metamorphic rocks are created from the transformation of existing rock types.  Metamorphism means “change in form.” Rocks under the earth’s surface change form by being subjected to heat, generally temperatures from 300° – 400°F, which can cause both physical and chemical changes in the rock itself.

Sedimentary Rock? Sedimentary rocks are formed by the solution of mineral and organic particles within bodies of water. Sedimentation is the name for several different processes that cause mineral particles and organic particles to settle and accumulate first into a dissolved solution and later into sediment.  Sediment is then transported to dry land by water, wind, or glaciers, or is left behind when the bodies of water dry up.  With time, the slushy sediment hardens into rock. Sandstone is probably the most well-known sedimentary rock.

Clay? Clay is a very fine-grained soil type made up of very fine minerals such as aluminium phyllosilicates, iron, magnesium, and a bunch of other chemicals I have never heard of. The minerals that make up clay soil are the result of weathering…the breakdown of rocks, soils, and minerals through contact with air, water, and living creatures.

Volcanic Ash? Volcanic ash is made up of pieces of pulverized rock, minerals, and volcanic glass that are created during volcanic eruptions. Pieces of ash must be less than 2 mm in diameter – larger fragments are referred to as cinders or blocks. At least this one I can understand!

Foliated? There are two types of metamorphic rocks:  foliated rocks and non-foliated rocks.  Foliated metamorphic rocks, such as schist and slate, have a “layered” appearance that has been produced by exposure to heat and directed pressure.  Non-foliated metamorphic rocks such as marble and quartz do not have the “layered” appearance.

And what is quartz? Quartz is the second most abundant mineral in the Earth’s continental crust, after feldspar. There are many different varieties of quartz, several of which are semi-precious gemstones. Quartz is the most common element of sand and sandstone and is used in glassmaking.  Quartz is almost immune to weathering and is a component of granite and other igneous rocks.

Aha- that’s why sand is coarse (quartz doesn’t “weather”) and clay is fine (its made up of materials that do weather or “breakdown”).

I think I’ll stop there. But for those of you who are curious, igneous rocks are rocks that are formed by the cooling and solidification of lava or magma. Granite and obsidian are igneous rocks.

So now, when someone says, “Llicorella is a unique soil made up of black slate and quartz,” what do you know?

Wine Grape Cheat Sheets: Grenache

grenacheThe Soundbyte:  Grenache (technically Grenache Noir) might just be the most popular “wing man” in the world of wine.  By that I mean that while Grenache is certainly capable of starring in varietal wines, it is one of the world’s most popular partners in a red wine blend.

In Spain, Grenache is often blended with Tempranillo, Cinsault, and a host of other grapes.  Grenache is one of the three amigos (Grenache-Syrah- Mourvèdre) of the Rhône Blend (otherwise known as G-S-M), while also playing a part in some of the more complex (ie., 13-grapes-or-even-more) wines of the Rhône.   Grenache is also made into dessert and fortified wines, and makes a world-class rosé.

Typical Attributes of a Grenache-based Wine:

  • A typical varietal wine made with Grenache might be described as soft on the palate, relatively high in alcohol and with aromas of spice and berries.
  • The texture of Grenache has been described as “rustic” or “fleshy”.
  • The grape tends to be thin-skinned and low in both color and tannin, however, these factors can vary depending on vineyard conditions and winemaking; some Grenache packs a powerful tannic punch.
  • In addition to varietals, Grenache is used in fortified wines, dessert wines, and delightful rosés; but its most common incarnation is as the backbone of hearty red blends.

Typical Aromas of a Grenache Based Wine:

grenache grapesFruity:  Blackberry, Blueberry, Strawberry, Cranberry, Currant, Cherry, Raisin, Plum

Spicy:  Black Pepper, Menthol, Licorice

Earthy:  Wet Earth, Leather, Forest Floor, Bramble, Tobacco, Smoke, Leather

Floral:  Roses, Dried Rose Petals, Violet

Oak-Derived:  Chocolate, Mocha, Cocoa, Vanilla, Sweet Wood

Where The Best Grenache is Grown:

  • In France’s Rhône Valley, especially the Southern Rhône, where it is the super star grape of Châteauneuf-du-Pape , Gigondas, and Rasteau. Typically, it plays a leading role in the blended red wines of the Southern Rhône.
  • The grape is part of the blend that is used to produce many delightful rosés throughout the Southern Rhône, including Lirac and Tavel.
  • Also in France, Grenache is grown in Provence, Rouissillon, Languedoc, Minervois, Fitou, and Corbières. It is also the leading variety of certain fortified wines in produced in Banyuls and Maury.
  • In Spain, where it is among the most widely planted red grapes in the country, the grape is called “Garnacha”.  Garnacha is main variety in Pirorat and Campo de Borja; and plays a role in the wines of Rioja, Navarra,  Somontano, Catalonia, and La Mancha.
  • Australia, where it makes some awesome varietals, including my favorite, d’Arenberg’s McLaren Vale “The Custodian” Grenache.
  • California, where it has historically been grown in San Joaquin Valley and is now produced in many other regions such as Santa Barbara and Paso Robles.
  • Washington State is also getting into Grenache.
  • Several regions throughout the south of Italy, particularly Sardinia, where it stars in the wine known as Cannonau di Sardegna.
