Notes from our testing
Regular Baja Blast is around 11 Brix on its own — add spirit and nothing else.
This is the rare case where the mixer is already calibrated. Mountain Dew Baja Blast comes in near 11 Brix, which sits inside our sugar window with no adjustment at all. All you are doing is adding alcohol without knocking the sugar out of range, and the easiest way to do that is to accept a slightly lower ABV.
Ten ounces of Baja Blast to 3 oz of blanco tequila or vodka lands around 9% ABV and 10 Brix once the spirit dilutes the soda. That freezes reliably. Push the spirit to 5 oz and you are near 14% and 8.5 Brix, which is right at the edge — it works on the FS605 and FS701 profiles and struggles on the FS301.
Go flat first. Pour the soda and let it sit uncovered for twenty minutes, or stir it hard. Dumping fresh soda straight into the chamber foams up over the max line and makes a mess of the lid seal, and the carbonation is lost regardless.
Baja Blast Zero is a completely different problem — no sugar means no freezing point depression from the mixer, and you need allulose to rebuild the Brix. That version is covered in the sugar-free guide.
