I bought four packs of sultanas to compare and contrast
They were all around $5 each, except the $4.50 Turkish brand Fuel from Aldi.The results varied greatly.
Those shrunken little Black & Gold brand fruit had bold flavour like a Shiraz wine for the intense acidity.
The Australian Sweet Vine fruit from Aldi were swollen and juicy in comparison, but the flavours weren’t as strong alongside the others (maybe I’d call it a Merlot).
That Turkish brand were nuanced and kinda mellow in comparison (like a Cabernet.
While the Woolies homebrand seemed to balance the sweet flavour in a fruit that was not too dried (like a blended wine, I guess).
