For a delicious and refreshing soda, it's hard to beat one you've brewed yourself. Generations of self-sufficient folks have been making their own beverages from local plants, often from the roots that give "root" beer and "ginger" ale their names. Today's home-brewers use many of the same soda ingredients as the old-fashioned recipes did, and the results are a delicious array of flavors with which artificial soft drinks just can't compete.

Homemade soda is simple and fun to make, and remarkably inexpensive. It's even cheaper to make most homemade soda recipes than it is to buy commercial colas. As an added benefit, many homemade sodas are healthier, too. When soda is made with all natural ingredients, you get all the flavor and healthful properties of the herbs and spices in the recipe, which might include ginger, anise, hops or licorice root. Natural sodas also contain yeast, which is a great source of B-complex vitamins. The most important health benefit of making your own soda, however, is that you can control the amount of sugar. Most commercial colas contain the equivalent of 7 to 9 teaspoons of sugar for a 12-ounce soda. When you make your own, you can add sweeteners to taste, and it's easy to brew great-tasting soda with 1/3 less sugar than commercial brands.

Brewing Basics

Store-bought soda is made with sugar — usually in the inexpensive form of corn syrup — water and artificial flavorings, and force-carbonated with carbon dioxide:

The gas is pumped directly into the beverage. In homemade soda, the main ingredients also are sugar and water, but in this mixture, the carbon dioxide is produced naturally through fermentation: Once the other soda ingredients have been mixed together, yeast is added to the beverage. Then, it's allowed to sit at room temperature for a day or two so the yeast cells can consume some of the sugar and form carbon dioxide bubbles as a byproduct. To retain this carbon dioxide, the soda must be stored in sturdy bottles.

A similar process is used to brew alcoholic beverages such as beer; the main difference is that soda isn't allowed to ferment for nearly as long. Instead, as soon as soda becomes carbonated, it must be refrigerated to slow the action of the yeast cells and prevent them from consuming all the sugar. Because the fermentation cycle is cut short, one glass of homemade soda usually contains less than 1 percent alcohol. If you started drinking your own soda by the gallon, the sugar would go to your head long before the alcohol would.

Necessary Equipment

To start brewing, you'll need to collect and sanitize a few plastic bottles, or the single-serving size. Many people prefer to use and reuse glass bottles as an eco-friendly option, but plastic bottles can be a good choice for beginning s soda makers because they're safer. If soda gets over-carbonated, the bottles could explode, and bursting plastic bottles are less dangerous than shattering glass containers. (Keep reading for more about how to avoid making overly fizzy soda.) If you decide to use glass bottles, make sure you choose those with thick glass and sturdy caps. Swing-top bottles, are a convenient choice for storing soda. Another good option is to buy glass bottles from a home-brew supply store because you can ask for containers strong enough to hold carbonated beverages.

When using plastic bottles, replace the caps after a few uses because the seals will begin to wear out. Also, never use plastic bottles from your recycling outlet because there's no way to know what the bottles previously held, and plastic can absorb toxic substances.

Sanitizing all your bottles and equipment is important because any bacteria unintentionally introduced to the soda can spoil the taste. An easy way to sanitize your equipment is to soak everything in chlorinated water (1 tablespoon of chlorine bleach to 1 gallon of water) for at least 20 minutes. Then, wash and rinse thoroughly because any leftover bleach particles can kill the yeast. If you prefer not to use bleach, one alternative sanitizes is Straight-A Cleanser, which does not contain chlorine or phosphates. In addition to bottles, a few must-have root beer supplies include measuring cups and spoons; a large stockpot made of stainless steel or some other non-reactive material; a large spoon for stirring and a funnel with a built-in strainer for bottling the soda.

Although not absolutely necessary, it's also helpful to have a candy thermometer, for measuring the temperature of the water, and bottle labels, for recording the date the soda was brewed. Another handy tool is a bottle brush for cleaning the insides of your bottles. A baby bottle brush will work, or you can buy a beer-bottle brush from a brewing-supply store for about $5.

Special Ingredients

Most of the herbs and spices for homemade soda are available in natural food stores. For brewing yeast and root beer extract, you'll find the widest selection from home-brew supply stores or by mail order.

Sassafras and Root Beer Extract. The true taste of root beer changed forever in 1960, when the Food and Drug Administration (FDA) banned sassafras from food products because of the suspected carcinogenic properties of safrole, which is present in small amounts in sassafras (as well as in basil, nutmeg and black pepper). Sassafras is the dried bark of the sassafras tree, Sassafras albidum, which is native to North America. Sassafras has been used in folk medicine for centuries, but tests done on laboratory animals found that rats given large doses of safrole developed tumors. As a result, the FDA restricts the sale of sassafras, which makes it difficult to find commercially. It is not included in any of the recipes here.

Today, commercial root beer extract is made with imitation sassafras, which is sassafras root extract with the safrole removed. Several brands are on the market. Most home-brew shops carry "Rainbow Homebrew," which has a good flavor. Another good extract is Zatarain's, a New Orleans company; this one includes birch and spruce oils. One bottle will make 4 to 5 gallons of root beer.

Yeast. Several different kinds of yeast can be used for brewing, but ale and champagne yeast are the best choices. Both types dissolve well and won't leave the unattractive clumps that bread yeast does, although bread yeast will serve the purpose if it's what you have on hand. Nutritional yeast will not work because the yeast cells are no longer active, and lager yeast is best avoided for the opposite reason: It can over-carbonate your soda.

Sweeteners. Most soda recipes call for sugar, but consider experimenting with different sweeteners. Honey is a delicious alternative to sugar, or use a mix of honey and sugar. Even no-calorie sweeteners, such as the herb stevia, can work, and for those who want to limit sugar intake this approach can be a lower-calorie option. The trick is to use just enough sugar to carbonate the soda and then to make up the difference with the no-calorie product. This method may still require using a substantial amount of sugar: Half sugar and half sugar equivalent is a good starting point.

Controlling the Carbonation

Soda-making is a relatively simple process, so when problems arise they usually fall into two categories: too fizzy or not fizzy enough. For soda that isn't fizzy enough, the easiest strategy is to leave the bottles sitting at room temperature for an additional day or two. As a last-ditch effort to save a batch that shows no signs of fizziness after a few days at room temperature, add an extra pinch of yeast.

Over-carbonated soda is a bigger problem. Keep in mind that homemade soda is almost always more carbonated than store-bought soft drinks. As long as you use plastic bottles instead of glass, over-carbonated soda isn't dangerous, but it can make quite a mess if the bottles burst. Always open soda bottles slowly, and if in doubt, open them outside. If you plan to let your soda carbonate in an especially warm room, consider reducing the amount of yeast in the recipe by half because yeast goes crazy in a warm environment.

Most importantly, always keep bottles of carbonated homemade soda in the refrigerator. Don't leave full, or nearly full bottles of soda in a warm area, and if you do, remove the bottles' caps.

After three or four weeks in the refrigerator, the soda will have lost most of its carbonation, and if you're not planning to finish the bottle, pour it out. However, disposing of home-brewed soda usually isn't a problem — leftovers are rare!

I typically use 3/4 to 1 cup of granulated sugar for a 2 liter bottle of soda. I assume that the active yeast used for the carbination consumes part of this sugar thus creating the by product of the C02 that becomes the carbination. I am wondering how much sugar the yeast actually consumes in that 3 to 4 day period before I drink my soda. I'm sure there are variables at play here but it's an interesting question to ponder.

Stella, you can get yeast nutrient at any beer and wine making supply store, and I've also heard some yeasts are worse about the sulfur smell than others so maybe try switching to a different yeast, too. It's typically less of a problem with beer because the longer fermentation time lets the smell dissipate, day two or so is usually when it's about the strongest!

Some fabulous recipes here. I'm especially excited to try your grape recipe. I think homemade fruit sodas are the best. I found some other great fruit soda recipes here: http://homemadesodaexpert.blogspot.com/

I have made ginger ale using a solution of ginger, water, lemon juice, orange juice, and sugar, mixes with Ale yeast. After allowing fermentation to proceed for 2 days and then refrigerating for a day, I notice a slight sulfur odor from the soda. I have heard that I should add a nitrogen source to the mixture so that there is enough nutrient for the yeast. Could anyone advise on a good method to reduce the sulfur odor and best source of nutrient? I have tried inactivated bakers yeast... waiting to see how this works. Thank you.

If you plan to use wild or fresh ingredients, I would try to kill off any bacteria that might be in the fruit like you do in wine making. Zoloftzantac, try to mash up the fruit like you intend and add Camden tablets to the juice to kill off wild yeast that would be on the skin of the grapes. Refer to wine making books or a brew shop near you to ask about the tablets. I make wine from fresh fruit and let me tell you, some funky stuff gets in there if you done sterilize the fruit first!

Great article! :) I don't have the answer to CJB's question, but I can tell you that if you try this with commercial grape juice, try to find one without preservatives. Getting yeast to grow and preservatives don't go hand in hand. I picked about 5 gallons of wild grapes today and I plan to try this recipe. I'm going to crush the grapes with my potato masher and then squeeze the juice out of them by hand with my jam bag. If you try with fresh grapes you may want to let your juice clear for at least a few days and then siphon off the clear stuff from the top for your soda or else your soda will have a lot of cloudy junk on the bottom. (but of course you'll have some lees down there from the yeast anyway so it isn't a big deal)

In your grape soda recipe, you call for 1/2 gallon of grape juice. What are you considering grape juice? I have made it by putting grapes in a stock pot, adding a little water, just enough to prevent sticking, until the grapes start to juice. Then mashing them down, bring to a boil and straining out the grapes. Is this what you want me to use? Or are you calling for a commercial grape juice?
