SUGAR CONTENT OF ALASKAN APPLES AT THE SEPTEMBER 1996 APPLE-TASTING
by Dwight Bradley
In the last Newsletter I reported on the September 1996 apple tasting, but forgot to include data on the sugar content. Bob Beyer took a slice of each apple that we tasted and squeezed a bit of juice into an refractometer, which measures sugar content in brix (I don’t find “brix” in my dictionary). So here again are the apples, this time in order of sugar content; the average tasting score (on a scale of 1-10. with 10 highest) is also given.
The sweetest apple was an unknown crab, which looked like Dolgo, with a brix of 17. It wasn’t a particularly sweet-tasting apple; in fact it was puckery-tart. This and. the other top finishers did not do especially well in the taste testing. The two top finishers in the tasting. Ginger Gold and Oriole, did have fairly high sugar contents, but so did a lot of mediocre varieties.
Some of the varieties with low sugar contents simply weren’t ripe. Others, such as Westland and Heyer 12, were plenty ripe and just never do get much sweeter than the ones we tested.
Refractometer measurements like these will come in handy in selecting varieties to mix for sweet and hard ciders with the proper balance. Novosibirsk! Sweet has great potential as a sweeting variety because its acid content is so low.
