Jurancon sweeties fit the bill for me. That light honied touch sits well with the acidity of the berries. Not masqueing it with too much sweetness, and allowing the acidity of the berries to cut through the sweetness.
Looking at previous comments about Moscato D’Asti, puts me in mind of Dom Montesquiou La Bulle, a Jurancon Cremant, whilst not as sweet as Moscato, has that lovely honied vein, so that would work aswell.
