A lot of shoppers would rather spend more for a six pack of single sized serving bottles than pay less for a two liter bottle of soda. The volumes of both options are just about the same so why do they pay more? It's all about the convenience. For starters, single sized servings are handy to just grab one and go. The other and much more important reason is that as opposed to a two liter bottle which will go flat if left for too long single sized servings won't. So before you get lost in the beverage aisle attempting to make a decision here are some facts you should give some thought to.

Oxygen is crucial to our existence and it is an invisible, odorless and apparently harmless gas. It is really until such time as it encounters the food we eat. Oxygen is highly reactive and bonds chemically with compounds present in food, altering their properties. Freshly bottled soda has almost no oxygen in its content and plenty of carbon dioxide (the reason for its fizziness). The moment you screw the cap off the CO2 goes out and the air replaces it. This is the reason your beverage quickly goes flat.

You can get rid of the air and replace it with more CO2 if you are willing to go to the trouble. If you burp the bottle by compressing it until the liquid rises to the rim then capping it you'll get rid of most of the air. The next phase is to restore the CO2 which isn't as easy. If you've got easy access to dry ice, then drop a 3-4 gram pellet about the dimensions a pinto bean into a 2-liter bottle that's a third empty, completely burping the bottle before capping. Use 8-10 grams if it's half empty. You will need to eliminate all the air #AND# replace all of the co2 which was lost to be effective. If you wish to go to the trouble of pouring the remaining contents off into a smaller sized bottle which can be completely burped, you're in business. That may be too much effort to recarbonate 80-cents worth of pop - you decide. The alternative is to simply obtain a home carbonation unit. You can find one on the web for between $100 and $250. Some manufacturers will void your warranty if you use the machine with anything besides water. Therefore you can't carbonate your apple juice, grape, watermelon, cantaloupe and pomegranate juices.

For the very cheap at heart, a teaspoon of sugar and a pinch of brewer's yeast will recarbonate your drink if you set the concoction in a warm closet for two weeks. Make sure to burp it! Not certain about that one? Try joining 2 bottle caps with a piece of clear tubing and screwing them onto two bottles - one bottle containing a beverage and the other vinegar + baking soda. CO2 from the vinegar bottle goes through the tube into the beverage bottle. This gadget sells online for about $7. This kind of set up makes it darn near impossible to get rid of the air though. A lot of companies suggest heavy scuba bottle sized co2 tanks, high pressure hoses, heavy duty industrial fittings and clamps. This equipment is effective and allows you to execute your carbonation in bottles that can be burped in advance. It presents a substantial investment, and you may have problems choosing an industrial gas tank that goes well together with your kitchen decor.

To be honest,the best thing in the world is a home soda fountain. When I bought my first seltzer machine I made a step forward to a happier ad healthier life!
