Fizzy. When I was a kid, we had a seltzer maker. It was this gleaming chrome bottle that accepted CO2 cartridges. There’s nothing like fresh seltzer. Yet, over the decades, DIY seltzer fell out of favor…until SodaStream. The company and its home brew device let you make seltzer and other flavored drinks at home and with a lot less sugar than, say, a Pepsi. Now Pepsi’s buying Soda Stream for $3.2B. Pepsi hopes Soda Stream will help boost its healthy-drink offerings. As for me, we get our pre-made seltzer from plastic bottles. It’s just alright.
