Things to Consider Before Buying Tonic Water

Most people would agree that tonic water is an acquired taste. Here are a few key points to take into account before choosing the best tonic water if you’re new to it.

• Container

You will find different kinds of tonic water in separate containers at any supermarket. There are tonic waters in plastic bottles, glass bottles, or cans. When picking the best tonic water for you, the ones in glass bottles are the best choice.

The level of carbonation is essential, and glass bottles hold up carbonation better than plastic bottles or cans. There are also tonic waters in champagne-sized glass bottles, which is perfect for when you are hosting a small party or gathering.

• Price

If you are looking to buy the best tonic water with outstanding quality, you may need to check out the prices first and see if it fits your budget. There are premium tonic waters, and there are supermarket own-brand versions. You will find that the premium ones are more expensive.

The reason for the price gap boils down to their ingredients. The own-brand versions use cheap artificial ingredients to cut the cost. The downside is it tastes too sweet for tonic water. So sweet that it cancels out the original bitterness of tonic water. Buying cheap tonic water may mess up the drink you're concocting.

• Carbonation

Its carbonation determines the quality of tonic water. More carbonation means excellent quality. Avoid supermarket brands if you want your tonic water to taste good. Go for the ones in glass instead. They have better carbonation and taste better.

• Sweetener

Another factor that contributes to the taste of tonic water is the sweetener used. Before you purchase a product, make sure you read the ingredients in the container. It's best if you go for sweeteners like agave syrup or cane sugar. Avoid high fructose corn syrup if you are particular with your sugar intake.

• Level of Quinine

Tonic water is carbonated water infused with quinine and a bit of sweetener. Although there are brands that produce tonic water without quinine, most of them incorporate this main ingredient. If you've had a bad reaction to quinine before or are susceptible to it, you must take caution and check out the quinine level in a product.
