What are the different types of Moutai?

Could you please elaborate on the various types of Moutai that exist? I'm intrigued to know if there are any distinctions in terms of their production methods, flavor profiles, or even their rarity. Are there any special editions or limited releases that collectors should be aware of? Additionally, are there any factors that contribute to the price differences among the different types of Moutai? Your insights would be greatly appreciated.
