USDA published results of the first maturity tests for Florida’s 2018/19 early and midseason oranges and for grapefruit. For early and midseason oranges tested, the 2018/19 solids to acid ratio was lower than in 2017/18 but higher than other recent seasons. Unfinished juice per box was slightly lower than last season and slightly higher than the five-year average. Solids per box were down 3 percent from last year and from the five-year average. White grapefruit saw an increase in its solids to acid ratio from last season: 6.45 this season compared to 6.39 in 2017/18. Red grapefruit’s ratio declined slightly, to 6.79 from last September’s 6.89.
