The owner boards in Antibes and asks, before the passerelle is even stowed, what coffee you carry. The last chief stew left two unlabelled foil bags in the dry store and a tin of something that smells of nothing. If you cannot say what species, origin and roast you are pouring, you cannot answer a guest question, and you cannot buy well for the next charter.
Two Species That Matter
Commercial coffee is dominated by two species. Arabica (Coffea arabica) is what specialty coffee is built on; Robusta (Coffea canephora) is cheaper, harder and higher in caffeine.
| Arabica | Robusta | |
|---|---|---|
| Altitude | Typically 800-2,200 m | Lowland, to ~800 m |
| Caffeine | ~1.2-1.5% | ~2.2-2.7% |
| Acidity | Higher, brighter | Low |
| Body | Lighter to medium | Heavy, rubbery |
| Typical flavour | Fruit, floral, chocolate, caramel | Woody, grain, burnt rubber, peanut |
| Crema | Moderate | Abundant, persistent |
| Price | Higher | Lower |
Robusta is not automatically bad. A small proportion of well-grown robusta in an espresso blend adds body, crema stability and a bittersweet backbone that survives milk. Traditional Italian espresso blends often run 10-30% robusta. A 100% arabica label is a marketing signal, not a guarantee of quality.
Where It Grows and How It Tastes
Coffee grows in the bean belt between roughly 25 degrees north and south. Altitude, rainfall and varietal drive the cup, but origin gives a useful shorthand.
| Region | Typical character |
|---|---|
| Ethiopia | Floral, jasmine, bergamot, stone fruit, tea-like |
| Kenya | Blackcurrant, tomato, intense acidity |
| Colombia | Balanced, caramel, red apple, medium body |
| Brazil | Nutty, chocolate, low acid, heavy body |
| Guatemala / Costa Rica | Cocoa, orange, clean sweetness |
| Sumatra / Indonesia | Earthy, herbal, cedar, syrupy, low acid |
| India / Vietnam | Often robusta; spice, wood, high crema |
Single Origin vs Blend
- A single origin comes from one country, region or farm. It showcases distinctiveness and is a talking point for guests, but can be unbalanced as espresso.
- A blend is built for consistency: a chocolatey Brazilian base, a bright Central American for lift, sometimes robusta for crema. Blends are more forgiving in a seaway and easier to reorder.
- Most yachts run a house espresso blend plus one rotating single origin for filter or the interested guest.
Talking About It Without Bluffing
Acidity in coffee means brightness, not sourness from bad brewing. Body is weight in the mouth. Sweetness is the goal of good extraction. Learn the three descriptors on your bag and use them honestly. Guests forgive "it is a washed Colombian, caramel and red apple" far more readily than invented tasting notes.
Onboard Notes
- Keep the roaster's bag or a photo of the label. Reordering "the nice one" mid-Med is how you end up with the wrong coffee at Cannes prices.
- Expect guests who ask for decaf, half-caff, or 100% arabica for caffeine sensitivity. Robusta carries roughly double the caffeine, so an espresso blend with robusta is a genuine consideration for a sensitive guest.
- Do not describe coffee as organic, fair trade or single estate unless the packaging says so. A confident wrong answer is worse than an honest check.
- xplor is not an accredited GUEST provider. These lessons are preparatory study only: nothing here awards a unit, certificate or qualification, or counts toward one.
