The only ginger scent I've ever used in CP is Ginger Milk from MajesticMtnSage. Out of the bottle it smells delightfully just like its name (gingery and milky), but in soap it smells more like gingerbread.
Ginger Essence from Sweetcakes is the only ginger I have ever liked. I mix it with two other fragrances, but the blend is mostly Ginger Essence. I don't buy much from SC due to their high prices and high shipping, but this one I will buy. I love ginger and have sampled many, but I'm done after trying this one.
The Ginger from MMS smells much better than the Ginger Milk. That's what I use. It is a spicy scent with dry ginger notes, and light discoloration. The BB Ginger Patchouli smells like fresh sawdust to me as if somebody just cut a piece of wood. I didn't smell ginger or patchouli. The ACS Hawaiian Ginger is not bad if you don't want it to last for a long time. It becomes more generic with time.
