Loon NYXX Pouches immediate burning?

Got my hands on some Loon NYXX 14mg wintergreen pouches after exclusively using Zyn 6mg pouches.

I believe they are wet pouches. I start to get a pretty intense burning as soon as I pop one, but after about a minute it starts to go away and is gone after two minutes. After that they are super comfortable, more so than Zyn pouches in my opinion. Does this track with anyone else’s experiences?
