Shafer Vineyards Relentless review: Which food pairs well with it?

Shafer Vineyards Relentless is a bold wine with intense flavors, as such, we recommend to pair with equally strong flavor dishes.

Classic appetizers are veal ragu pasta, grilled vegetables, onions and mushroom dishes to name some.

Meat wise go for burgers, BBQ ribs, and lamb for example.

If you are a cheese lover our recommendations for you are semi-hard and blue cheeses like Cheddar and Gorgonzola for example.

Shafer Vineyards Relentless review: What's its alcohol content?

Shafer Vineyards Relentless wine’s alcohol content is 15.8%.

In case you wonder about alcohol content or more precisely Alcohol By Volume, i.e. ABV, measure the alcoholic strength of a drink.

There is a direct relationship between the sugar left in the wine after the alcoholic fermentation has taken place, i.e. Residual Sugar or RS, and ABV.

During alcoholic fermentation, the yeast transforms the sugar in the grape juice into alcohol.

Grapes with high residual sugar will therefore produce dry wine with a high ABV.

How many calories are in a glass of Shafer Vineyards Relentless wine?

According to the U.S. Department of Agriculture [1] a 5-ounce glass will contain about 120 to 130 calories.

Alcohol contains 7 calories per gram. So a wine with high ABV will have a higher calories per glass than a wine with low ABV.

Furthermore, sugar contributes to the calorie count.

A dry wine will usually have 4 calories per grams vs a sweet wine that will have around 20 calories per grams of carbs, which include sugar.

What is Shafer Vineyards?

Here is an extract from the Shafer Vineyards website:

“The Hope family has been farming in Paso Robles for more than 30 years.

When they arrived in this barely-discovered region, they planted apples and grapes.

Little did they know that the rolling, oak-studded terrain of Paso Robles would one day become a viticultural terroir of significance and one of the top winegrowing regions for quality red wine within the Central Coast.”

Syrah and Shiraz are two different names for the same grape that though produces different styles.
