I quite often use lemonade as a mixer but I find all the bottles I pick up, the fizz only lasts for a couple of days.
Is there some kind of safety regulation in place now for companies producing carbonated drinks to not be very fizzy.
I remember years ago a bottle of pop would last for a week with plenty of sparkle left in it.
I remember a certain famous brands T.V. advert used to boast how fizzy their lemonade was........not any more. Instead of "Fizzzzzzzzz", after two days it just goes"F" :0)
Speculation here - have they, the beverages industry, cut back carbon dioxide levels in drinks - that's the carbonation compound that gives the fizz.......anybody work for Coca Cola or Pepsi around here?
maybe it's something to do with the plastic bottles they use these days, instead of the glass ones. perhaps they're not as robust and can't resist as much pressure.
Yes I realise that the fizz in champagne is from the sugars involved but if the reason lemonade and other fizzy drinks have had the fizz taken out is for safety reasons such as a wayward bottle top flying up or spillage then champagne and other sparkling drinks are just as likely to cause an injury or accident.
I'm not for one minute suggesting companies reduce the bubbles in champagne but rather put more in my lemonade.
Our local pub landlord will only supply lemonade for mixers from glass bottles. Like you, he has found that with plastic bottles the fizz doesn't last. This is because once the plastic bottle is opened, then closed, the carbon dioxide comes out of solution and tries to blow the bottle up as you would a balloon. With a glass bottle, the gas is more constrained, and more gas remains in the liquid.
