The water content of Nelson may reside around 75%, making it 2-5% drier than most other juneberry varieties. While its acid content is fairly low, Nelson was one of the most acidic varieties available, giving it a pH of 3.65 (most varieties have a pH around 4). Martin (3.71) and PAR90 (3.70) had the second lowest pH values. Nelson also had the second highest mean brix value (18.8), during a 3 year study in Saskatchewan.

The water content of Pembina may be as low as 71-72%. Other fruits generally reside between 80-90%, and most other juneberry varieties reside around 77-80%.
Pembina had the highest mean brix value (20.1) during a 3 year study in Saskatchewan (most were between 14 and 17). It may also have a sorbitol content higher than the average variety, based on another study. In fact, its sorbitol content was higher than Smoky in-spite of having a lower overall sugar content.

Smoky is the most commercially cultivated variety in Canada.
Smoky may have a higher sorbitol content than normal (3.37g/100g in a one year study). This is compared to Honeywood (2.25g/100g), Martin (2.41g/100g), Pembina (1.84g/100g – excluding some data that seemed highly erroneous), and 3 unnamed varieties (1.8 to 2.49g/100g). In another study, Smoky's sorbitol level was more in line with, but slightly higher than, some of the other varieties, such as Martin and Theissen (Pembina managed to be higher than Smoky).
