When tested on animals, resveratrol has also been shown to improve markers of longevity.  Who couldn’t stand to use a few extra months or years on this planet while indulging in some delicious wine?
As with white wine, you need to steer clear of sugary reds in favor of the varieties below.
If you plan to have a romantic evening in, complete with a three-course steak dinner, then you may want to find the perfect wine companion for your meat. Merlot might just fit the bill and allow you to keep keto with just 2.5g net carbs in many bottles. Merlot will have blackberry, black cherry, plum, cocoa, vanilla, clove, or cedar notes.
One of the zestiest-tasting red wines that you will find, chianti is a low carb wine that will give you just 2.6 grams of net carbs per serving. Chianti is usually a medium-bodied wine, but it still has a powerful flavor profile. It often has notes of cherry or strawberry as well as herbs or smoke.
With about the same net carb count as chianti, cabernet sauvignon is another grape variety that makes full-bodied wines that embrace the flavors of dark fruits, like black cherry and blackberry, along with spices, tobacco, wood, and sometimes vanilla. Best paired with red meat, this is a timeless wine that goes with your ribeye steak or just a good burger on a lettuce wrap. It is also the star of the show when reduced into sauces.
Out of all the red wines that promise to be low carb, pinot noir has the lowest net carbs (2.3g). It has a lighter body than many reds, but carries complexity and notes of cherry and raspberry. When oak-aged, it may also have tasting notes of vanilla and spice depending on the technique used. Pair it with pork, steak, or venison for a flavorful meal.
Tricks to Finding Low Carb Wines
One trick to use when trying to find keto-friendly wines is to look for higher alcohol wine. Wines with a higher percentage of alcohol are usually that way because more of the grape sugars have been converted to alcohol, leaving less residual sugar behind to push you out of ketosis. To stay on the safe side, you’ll also want to avoid grape varieties and winemaking regions that usually produce sweeter wines, such as the varieties riesling, moscato, gewurtztraminer, zinfandel, and chenin blanc, and regions like Sauternes. Avoid dessert wines like ice wine and fortified wine like Port.
Another trick to make sure that you do not overindulge and kick your body out of ketosis is to measure your servings at 5 ounces each to ensure you’re not going over your carb count. Keep in mind as well that regardless of carb count, wine still contains calories that can add up and slow your progress, if weight loss is one of your goals on keto.
