Ice, Garnish and Bar Hygiene

Explains how ice controls chilling and dilution, the ice types and their uses, ice and garnish hygiene, and general bar food-safety practice onboard.

Two Negronis, same gin, same vermouth, same Campari, same jigger. One tastes bright and cold; the other tastes watery and flat. The only variable was the ice. Ice is the ingredient most bartenders ignore and the one that most often ruins a drink.

Why Ice Matters

Ice does two jobs at once: it chills and it dilutes. A finished cocktail is typically 20–25% water by volume, and that water is not a defect — it is what makes the drink drinkable. Your job is to control the ratio.

  • Bigger, colder, harder, drier ice = slower melt = more chilling per unit of dilution.
  • Wet, small, warm ("cloudy freezer-tray") ice melts instantly, over-diluting the drink before it is even cold.
  • Ice sitting in a pool of meltwater is already half-lost. Drain the well.
Ice type Use
Cubed (2.5cm) Shaking, stirring, general highballs
Large cube / sphere Spirit-forward drinks served on the rocks — slowest dilution
Cracked Faster chilling, more dilution — juleps, some tiki
Crushed / pebble Mojito, Julep, tiki — heavy dilution intended, drink is stirred and refreshed
Block Punches and large-format batches

Always fill the glass with ice. A glass half-full of ice melts faster than one packed with it — less ice means a warmer, more watery drink, not a stronger one.

Ice Hygiene

Ice is a food product and one of the most common sources of contamination onboard.

  • Use a dedicated plastic or metal scoop, stored outside the ice, not in it. Never scoop with a glass — if it chips you have invisible glass in the ice well and the entire well must be emptied, cleaned and refilled.
  • Never return unused ice to the well. Never put anything in the ice well but ice — no bottles, no cans, no fruit.
  • Ice takes up smells. Keep the machine and the well clean, covered, and sanitised daily.

Garnish

The garnish is aroma and appearance, not decoration for its own sake.

Garnish Handling
Citrus twist Cut with a peeler avoiding the white pith. Express the oils over the drink (skin side down, squeeze), rim the glass, then drop in or discard
Wedge / wheel Cut same-day, keep chilled and covered
Olive / cocktail onion Keep refrigerated in brine; use tongs
Mint sprig Slap once in the palm to release aroma — do not shred. Keep in cold water or damp cloth
Dehydrated fruit Airtight container, dry, no fingers

Prep only what a service needs — yesterday's oxidised garnish tray is worse than no garnish.

Bar Hygiene

  • Wash hands on returning to the bar and after handling waste.
  • Use tongs, forks or gloves for anything going into a guest's glass. Fingers never touch the garnish or the ice.
  • Sanitise pour spouts, jiggers, shakers, boards and knives regularly; wash tools between drinks with different ingredients — dairy, egg and coffee especially.
  • Fresh juices, syrups, milk, cream and egg are perishable: label with contents and date, refrigerate, and follow the yacht's discard rules.

Onboard Notes

  • Ice is limited at sea. Know the machine's output, plan a big party ahead, and never let the well run dry mid-service.
  • Broken glass near an ice machine or a pool is an incident. Report it, and follow the yacht's glass-breakage procedure — it usually means dumping all ice within reach.
  • Sun and heat wilt garnish in minutes. On deck, keep the tray covered and on ice.
