Dark Chocolate and Whisky: A 70%, 85% and 90% Tasting Guide
A square of dark chocolate can change the way a whisky seems to taste. Try a creamy, fruit-led sherry-cask malt with one piece, then a mellow bourbon or smoky Islay Scotch with another, and the balance of sweetness, bitterness and spice may feel very different. This simple tasting board gives you a way to explore those contrasts without needing a complicated dessert. Three plain dark chocolates, three small whiskies, water and a few minutes of attention are all it takes. You might even find your favourite combination is the one you expected least.

At a glance
Serves four adults for a small tasting. Preparation: 15 minutes. Tasting: approximately 20–30 minutes. No cooking required. You need a board, a sharp knife or a way to break the chocolate, three small tasting glasses per person if available, a water glass and plain crackers.
Shopping list for four: 20 g plain 70% dark chocolate, 20 g plain 85% dark chocolate and 20 g plain 90% dark chocolate (60 g total). For a guided three-whisky flight, allow up to 10 ml of each whisky per adult (30 ml altogether per person). Provide plenty of water and keep pours optional; you can share bottles or use similar whiskies you already own.
Why chocolate percentage is only the starting point
The percentage printed on a bar describes how much of the recipe comes from cocoa ingredients, including cocoa solids and cocoa butter. A higher percentage generally leaves less space for sugar, so a 90% bar is often more assertive and less sweet than a 70% bar. But it is not a quality score: bean origin, roasting, added ingredients and the chocolatier's style all affect flavour. Even two bars marked 70% can taste surprisingly different.
For a simple comparison, choose plain unfilled bars rather than mint, orange or chilli-flavoured chocolate. Keeping the chocolate relatively consistent lets you focus on how cocoa intensity and whisky style interact. Valrhona's chocolate range includes examples from rounded 66% through bitter 70%, roasted 80% and tannic 85%, a useful reminder that dark chocolate is not one uniform flavour.
Build the tasting board
Step 1 — Break the chocolate into three groups
Leave the chocolate at a comfortable room temperature. Break each bar into small, roughly 5 g tasting pieces, giving everyone one piece from each cocoa strength. Put the 70% pieces at the left of the board, 85% in the middle and 90% at the right. Keep the wrappers nearby so anyone with an allergy can check the ingredients; milk, soya and nut cross-contact are common considerations.
Step 1 — Arrange the 70%, 85% and 90% chocolate in separate groups.
Keep a small gap between each group. If you are using especially large or intensely bitter squares, cut them smaller: the purpose is to notice flavour rather than eat a full dessert portion at once.
Step 2 — Pour small measures and set out water
Pour no more than 10 ml of each chosen whisky into separate glasses for anyone participating. That is a sample, not a full bar measure. Set out still water and plain crackers to reset the palate between combinations. If sharing tasting glasses, clean them between pours. There is no need to finish any measure, and a chocolate-only comparison works well too.
Step 2 — Pour small whisky samples and have water ready.
Step 3 — Start with 70% and a sherry-cask malt
Let a small piece of the 70% chocolate soften in your mouth, then take a tiny sip of a sherry-matured whisky. The GlenDronach 12 is one example. Its producer describes aromas of chocolate praline, sun-dried raisin and gingerbread, followed by orange and dried-fruit notes. With a gently bittersweet square, look for whether those richer fruit flavours seem more noticeable or whether the combination tastes too sweet for you.
The GlenDronach producer confirms maturation in Pedro Ximénez and Oloroso sherry casks. You could also try another sherry-influenced Highland or Speyside single malt; match the profile, not an expensive bottle.
Step 4 — Try 85% with a fruit-and-oak bourbon
Next compare an 85% piece with a small sip of Four Roses Small Batch bourbon, or a similar fruit-led American whiskey. Four Roses describes rich fruit, sweet oak, caramel and gentle spice. The idea is to compare the chocolate's firmer cocoa character with the bourbon's rounder aromatic profile. Does the chocolate feel softer beside it, or do the two flavours compete? There is no correct answer.
If the 85% chocolate is particularly bitter, compare the same bourbon against a 70% piece. Changing one variable at a time teaches you more than changing whisky and chocolate together without a note of what happened.
Step 5 — Finish with 90% and smoky Islay Scotch
For a bold final comparison, place a small piece of 90% chocolate beside a few drops of Ardbeg Ten. The producer describes smoky peat, sea spray, lime and an espresso-like finish. Those strong flavours could amplify the dry side of very dark chocolate rather than soften it. Some people will enjoy the intensity; others may prefer a sweeter bar with the peat. Taste the chocolate first and take only the tiniest whisky sip.
Keep this smokiest pairing until last so that the peat does not overwhelm earlier, lighter flavours. If 90% cocoa is not enjoyable on its own, do not force the pairing: use an 80–85% bar or a smaller bite. A different lightly peated whisky can also make the contrast gentler.
Three pairing ideas at a glance
70% dark chocolate + The GlenDronach 12 or another sherried single malt: compare cocoa with dried fruit, orange and warming spice. An approachable first combination.
85% dark chocolate + Four Roses Small Batch or a mellow bourbon: compare assertive cocoa with fruit, oak and caramel. A useful sweetness-versus-bitterness contrast.
90% dark chocolate + Ardbeg Ten or another peated Islay malt: compare dry cocoa with peat and espresso-like notes. This is an optional, challenging final comparison, not a guaranteed crowd-pleaser.
If you only own one whisky, try it alongside all three chocolate percentages. That is often the most revealing and economical version of this activity because the whisky stays constant.
A simple tasting checklist
Before the sip: is the chocolate fruity, nutty, earthy, sharp or creamy? Do you smell sweet oak, dried fruit, citrus or smoke in the whisky?
With the pairing: does the chocolate make the whisky seem sweeter, drier, more smoky, more spicy or less pleasant? Does the whisky make the cocoa taste fruitier or more bitter?
After a sip of water: would you choose the same combination again? Note your preference rather than giving the whisky or chocolate a universal score.
Serving tips, sensible swaps and allergens
Use modestly sized pieces and very small whisky samples. Serve at a comfortable room temperature; strong fridge chill can mute some aroma. Avoid pairing against heavy garlic, chilli or coffee immediately beforehand if you want to compare subtle differences. Keep water accessible throughout.
If your guests prefer sweeter chocolate, start with 60–70% rather than 90%. If you do not have bourbon, use a gentle unpeated Scotch for the middle comparison; if you dislike peat, swap Ardbeg for another sherried or bourbon-cask whisky. You can also serve the whole board with black tea or sparkling water and skip alcohol entirely.
Check every chocolate label for milk, soya and nut ingredients or cross-contact warnings. This guide is for adults who choose to drink alcohol, not a claim that chocolate alters alcohol's effects. Drink responsibly, do not drive after drinking and do not feel obliged to finish a pour. Read more at https://www.drinkaware.co.uk/.
Frequently asked questions
Is 70% dark chocolate the best place to start?
For many people, yes. It often leaves enough sweetness to make a first comparison accessible, but the best bar is one you enjoy on its own. Try two brands if you want to see how cocoa origins and recipes differ.
Does a higher cocoa percentage automatically mean better chocolate?
No. The percentage tells you the proportion of cocoa-derived ingredients, not the overall quality. Bean origin, roast, sugar balance and craftsmanship also matter.
Do I need the exact whisky brands mentioned?
No. GlenDronach, Four Roses and Ardbeg illustrate three broad flavour directions. You can use similar sherry-cask, fruit-and-oak bourbon and peated whisky styles.
Can smoky whisky work with chocolate?
It can be an interesting contrast, especially for people who enjoy bold flavours, but smoke and very bitter cocoa may reinforce one another. Start with a tiny amount and switch to a less bitter bar if necessary.
Can I host the tasting without alcohol?
Absolutely. Compare the chocolate bars by themselves with water between pieces, or add unsweetened tea. The cocoa-percentage comparison still works and no alcohol is needed.
