Tiers

Tiers are the different levels an effect can have when brewing a potion. The tier of an effect can vary from 1-3 (denoted with Roman numerals) and can not be improved once the effect has been infused using the bellows, meaning that the same effect can't be added multiple times. It is however possible to brew a potion with multiple effects with different tiers, for example a potion with a Healing II and Poisoning III—although this particular combination is obviously unadvisable.
The tier of a Potion is determined by the alignment of the potion itself with the symbol of the effect on the Alchemy Map. The better aligned the outlines are, the higher the tier of the Potion. The higher the tier of the Potion, the more gold you can ask for it. 
To better align the potion with the effect, you can use different ingredients to make different paths on the Alchemy Map, using different degrees of grinding and the ladle to refine the final position. 
Though not relevant in the early game, the angle of the Potion must also be within a certain range: 
Tier	Max ∆Angle	Max ∆Grains	
1 	180° (N/A)	500 (N/A) 	
2 	69.12° 	192 	
3 	9.36° 	26 	
"Grains" here refers to grains of either Moon or Sun Salt.
