Potions and Crafting Specializations

[GruffAndTumble]

Hey all. I can't figure out how the rules treat the interaction of Crafting Specializations and Potions. More specifically, the Frequency specialization (Power seems easy enough). With a bonus in frequency, do you make multiple dose potions, get doubled up slots, or just get no benefit whatsoever?

You get multiple uses as normal. I.e. with frequency +2 you still brew the same amount of potion but now that much potion is good for three dozes, not only one.
