Xpress is 40/60 VG/pg. Notice they list them opposite of the way most sites do. They list VG first, and the default that comes up on custom juices is not necessarily the recommended ratio. Xpress is just that, premixed. You can not specify your vg/pg ratio of Xpress juices.
Thanks for the info. I may have to give them a shot once I'm running low on juice again. It looks like they definitely have some fruit flavors I'm interested in trying.
