White port is a fortified wine from white grapes, from Portugal’s Douro Valley.
Another white port
Works perfectly, just check the style first. Bottles range from bone dry to intensely sweet.
Lillet Blanc
A solid stand-in. Swap it straight at the exact same measure.
Another solid choice, though it runs noticeably sweeter.
Bone dry with a salty, nutty edge. It leaves the glass drier, so stir in about half a barspoon of sugar syrup per 40 ml of sherry.
A Sauternes only matches a sweet port. It sits at a lower ABV, leaving you with a lighter drink.
It is made like red port: grape spirit stops the fermentation, so unfermented sugar stays and the strength rises at once. Sweetness is what varies most between bottles, and it decides how a drink built on it tastes.
Once opened, keep it in the fridge and finish it within weeks; the freshness fades after that.
