The bottles were washed with OneStep prior to bottling and dried on the bottle rack.
I don't think it is OneStep. I believe OneStep is Sodium Carbonate (CNa2O3) which, when combined with water, creates carbonic acid (H2CO3), hyrdoxide ion (OH-), and sodium (Na).
If you are salt sensitive, the sodium could raise your blood pressure. But, the amount would be so dilute - equivalent to a few grains of salt at the most in a bottle of wine.
