These were picked from pretty young trees, ~2 years in the ground only. I wanted to evaluate NZ Lemonade, and the Meyer lemon seemed to be a good comparison candidate. I heard the NZ lemonade is a low acid one. Meyer is also not the most sour lemon.
In this comparison, Meyer seems to be pretty sour, as NZ Lemonade is almost acidless. It can be eaten like an orange. It is actually very pleasant to eat, my family and I enjoyed it.
