As you’re probably aware pineapple is a tropical fruit, with sweet and juicy pungent flesh. It’s this sweet pungency that’s reflected in some wine aromas, though no actual pineapple is present. There is such a thing as wine made from pineapples instead of grapes, but we won’t get into that here.
As a tasting note, pineapple is aligned with other sweet-smelling exotic fruits like melon, banana, guava, mango and passionfruit. Its flavour profile is sweeter than the citrus fruits, but it has a freshness that distinguishes it from stone fruits, such as apricots and peaches.
You can find pineapple notes ripe white wines, such as a Riesling. Or you might find it in more traditional late-harvest examples, especially from cool regions like Mosel in Germany. It’s generally ascribed to the influences of Botrytis Cinerea, or Noble Rot.
First things first, it’s important not to confuse the flavour profile of coconuts with nuts. Coconuts are not nuts, they are drupes (stone fruits). Their distinctive flavour and aroma is distinct from either fruits or nuts, and can be found in products like coconut milk or oil, as well as the desiccated coconut you might have eaten in a Bounty bar.
In wine, coconut generally manifests itself on the nose as a kind of dulled sweetness, which doesn’t pique the senses in the same way as sweet fruit or honey flavours. Instead it is more heavily aromatic, which is why it’s categorised among the ‘kernals’ such as almond, coffee and chocolate.
Notes of coconut can come from esters, which are the chemical compounds behind many aromas. Specifically lactones, which are responsible for the peculiar sweet aromas associated with coconuts. Beverley Blanning MW goes one step further in her exploration of oak aromas: ‘beta-methyl-gamma-octa-lactone – that’s coconut aroma to you and me’.
Coconut is one of the key aromas that distinguishes oaked wines, and it’s usually counted as a tertiary aroma because it’s related to the ageing process. Oak flavours can come from contact with wood chips, staves or barrels. Coconut is strongly evoked by American oak, along with vanilla notes.
As with many floral notes in wine, rose is sweet on the nose but more bitter and austere on the palate. In this way it’s comparable to notes of violet and magnolia, stopping short of the slight acridity of lily or geranium.
You may find the flower referred to directly or as ‘rose petal’, as well in the form ‘rose water’ — which suggests it smells more like musky perfume, or tastes a bit like Turkish Delight.
The science behind rose’s flavour profile comes down to 3 key chemical compounds: rose oxide, β-damascenone and β-ionone.
Usually it’s the rose oxide element that makes it comparable with the smell of some Gewürtztraminer wines. They’re known for their highly aromatic qualities and signature lychee notes — a fruit which carries the same rose oxide compound.
β-ionone is also behind the aroma of violets, so it makes sense that violet-scented wines can sometimes harbour rose hints too — such as red wines made in Piedmont from the thick-skinned Nebbiolo grape. You can also look for rose notes in young Pinot Noir wines, particularly those made in Australia and New Zealand.
Note: Rose as a tasting note has little to do with rosé wines, which are named after their pinkish colour rather than for a floral character (see Spanish rosado and Italian rosato equivalents).
The idea of caramel being swirled through your wine might be pretty sickly, but if it features subtly as a tasting note it can bring a luxuriantly developed sweetness to the nose and palate.
Don’t be mistaken, no actual caramel has been magically formed in the bottle. The caramel-like effect is sometimes created by the vines being intentionally infected with botrytis cinerea, aka noble rot — a form of fungus that dries out the grapes, concentrating sugar levels. This practice is commonly used in the production of dessert wines, such as those of the Sauternes and Barsac appellations, or Trockenbeerenauslese wines from Germany or Austria.
Botrytis can also alter the mouthfeel of a wine, as it digests sugar and acids and excretes glycerol in its place. So the developed sweetness and silky mouthfeel can lead to an sensorial impression of smooth caramel.
Lastly, this clever noble rot injects an enzyme called laccase, which is responsible for oxidising the wine, producing flavours ranging from apricot and almond to toffee and caramel. It can also induce deep golden hues, so the wine appears caramel coloured, too. Look for it in other oxidised wine styles, such as in tawny Port or Palo Cortado Sherry.
Another way to create caramel flavours is by the use of oak, because it can appear as a secondary aroma from oak-ageing, along with butterscotch and vanilla. This can particularly be detected in Chardonnays aged in American oak, rather than French oak.
