Best Bitters for Old Fashioned to Enrich Flavors in Your Drink 


By  Genelia

What are Bitters?

Cocktails bitters have a much longer and richer history than most people know. Bitters date as far back as ancient Egypt, where they were strictly used for medicinal purposes. Over time, these flavor portals grew into the cocktail additive we all know and relish today.

Bitters are a combination of a concentrated tincture of water, and flavoring, typically from various herbs, spices, flowers and even fruit. The plant combinations are soaked in high-proof alcohol then drained and bottled. Traditionally, their flavor profile was bitter to help balance a drink's final flavor. Bitters are meant to be used in small amounts; just a few drops at a time can lift your Old Fashioned from flat to flavorsome.

Why Do Bitters Come in Small Bottles?

This goes back to the origins of bitters, when most were initially used as medicine. They were usually crafted in small doses, either straight or diluted in water or other liquids. Some presume alcohol spirits could have been one of the other liquids, hence eventually, the tiny bottles made their way behind the cocktail bar. Furthermore, bitters are high-proof and high-flavor, so a few dashes go a long way!

What Do They Do To Whiskey?

Bitters work remarkably well with various whiskey-based cocktails. According to experts, they provide additional earthy notes that blend well with the aromatic elements of whiskey that's aged in wood barrels. Bitters also add volume since they extend the finish on your palate like tannins do for wine.

What to Look for in the Best Bitters for Old-Fashioned

1. Flavor

There are several types of bitters, and each recipe brings a unique flavor to your drink: Aromatic bitters are classic, a harmonious blend of bitter and herbal notes. Citrus bitters are like a high-note citrus solo, backed up by other muted flavors. Floral bitters deliver a strong fragrant or floral main event. Finally, celery bitters work magic with savory drinks.

You can also consider twists such as smokey, chocolatey, savory, grapefruit and even cardamom bitters. If all-natural ingredients matter to you, look out for brands with pure bitters. However, it's worth considering that some of the leading bitter brands add artificial color to their products.

All in all, we recommend having a couple of different bitter flavors in your home bar so that you can explore the different characters each option brings to your Old-Fashioned.

2. Alcohol Percentage

Most bitters have around 45-50% alcohol by volume, but you only need a few drops at a time. You can also consider glycerin-based bitters. Since glycerin is a sugar alcohol, it serves as a shelf stabilizer while also imparting a sweeter taste.

Frequently Asked Questions (FAQs) on Bitters

1. Do bitters contain alcohol?

As mentioned earlier, yes, bitters contain alcohol, some as high as 50% ABV. However, since you only use tiny amounts, the actual alcohol you add to a drink is virtually negligible and doesn't change the cocktail's overall ABV. Furthermore, you can consider non-alcoholic options if you're abstaining.

2. Can you drink bitters on their own?

Yes, but not all. In any case, bitters are mainly meant to be added to drinks, alcoholic or otherwise. Some bitters can also be added to soda water or ginger ale to cure hangovers. Plus, you can also use them for cooking as well.

3. How much bitters should you add to Old-Fashioneds?

Ideally, you should add bitters the same way you season food with salt and pepper. A drop or two will add a remarkable depth of flavor, enriching your Old Fashioned right away.

4. How should you store bitters?

You can store your cocktail bitters on your bar cart if their ABV is 20% or higher. They'll practically stay good forever. Anything lower has to be refrigerated. That being said, there's no conventional rulebook; if you are in doubt, store it in the fridge.
