Peach purée is peach flesh blended and sieved smooth, added to drinks as a fruit base.
Fresh fruit blended and sieved is the same thing to order, and it needs lemon immediately or it browns while you work. Body is what separates it from a juice, and sweetened bar purées put the recipe out by a barspoon or more.
Peach nectar
Purée let down with water and sweetened, sold to drink, and using it where purée was meant leaves a Bellini thin and flat.
White and yellow peach purée
White is floral and delicate, yellow is fuller and more acidic. A Bellini written for white peach tastes coarse made with yellow, and the label rarely says which is in the tub.
Fresh keeps a couple of days refrigerated and freezes well in portions. It browns at the surface as it oxidizes, which a squeeze of lemon slows. Commercial keeps to its date and belongs in the fridge once open.
