Freshly squeezed orange juice would be better than "concentrate".Concentrated juice has the water removed and is then frozen for storage,transporting.With water added later
Not made from concentrate would be second best in my opinion, nothing is removed, and nothing is added.
Concentrated juice would come third.
edit: just to mention that ALDI sell a 500ml Orange juice (not from concentrate), usually found in the fridges for 99cent. Its the best shop bought orange juice i've ever had
