Disappointed- aspartame is back
on June 10, 2026
Posted by: Sara
Why on earth did you change back to aspartame for this? Now none of the pepsi has aspartame free which is literally the only reason I bought a soda stream.

Tastes like the real thing

Great quality product and tastes like the real thing. You can mix up the strength and carbonation to get the consistency you desire. Overall would recommend.

New Syrup Bottle Design is Bad
on February 3, 2026
Posted by: H J.
I have been buying the Diet Pepsi syrup for several years. Two days ago my new batch of bottles came. They redesigned it. The old bottle had a screw top that doubled as a measure for making the soda. The new one lacks that feature. Bad design equals more to do to make the soda and more to clean :(

Formula Has Changed!
on October 7, 2025
Posted by: David
This used to be the only Diet Pepsi product without Aspartame. I just went to order more and checked the ingredients. Formula has changed. Aspartame and Ginseng Root Extract has been added. I have a bad reaction to both. Not happy.

Great taste!

The soda stream machine is fantastic and I make my favorite soda, diet Pepsi. I'm a big diet Pepsi fan and usually have 10 bottles in the fridge! So easy to use the sodastream and I save money as well.
