If you need fizz, Be'er Mayim is the way to go. Taste isn't bad either.
Yup I like BMC. Great strong long lasting fizz.
Though I may add that all fizz is not created equal.
I find that there are many variations of fizz.
Some last. Some don't.
Some are strong. Some are soft.
Some have bigger bubbles. Others are smaller.
And you can have a combo of soft long lasting bubbles.
I don't know all the diff particularities but I think Perrier has the best tasting seltzer fizz (although not the longest lasting). And I absolutely love the Israeli Schweppes Mugaz fizz from any other drink.
