What are the essential criteria for choosing a quality Irish Coffee glass?
Summary: Limonadier suggests choosing a cocktail glass for preparing an Irish coffee. Three important characteristics should be considered: thermal resistance, a thick wall for optimal insulation, and a stable, thick stem. Unlike classic cocktails, Irish coffee is served hot. This necessitates using appropriate glassware to prevent accidents, such as cracking.
The 4 essential pillars of quality:
1. Certified thermal resistance: the absolute safety criterion
ISO 7086 certification recommends that cocktails or beverages served between 70 and 85°C be served in glasses with borosilicate glass walls. This is because only these materials possess the characteristics to withstand the coefficient of thermal expansion necessary for beverages served at high temperatures.
2. Optimal thickness: between insulation and handling
As we mentioned, the wall thickness of an Irish coffee glass should be at least 2 to 3 mm. Below this thickness, the thermal insulation is compromised and the risk of burns increases. Conversely, a thicker glass will add weight to your tableware, but some people appreciate the added weight.
3. Base stability: preventing tipping
A detail for some, but very important for others: the base of your mug should be approximately 6cm in diameter for a 250ml capacity. This is the ideal size for a low center of gravity. So, if you have the choice, remember to check this size when making your purchase.
| Criteria | Entry-level (5-12€) | Intermediate (15-28€) | Premium (€30-50) |
|---|---|---|---|
| Material | Basic borosilicate | ISO certified borosilicate | Borosilicate + reinforced treatment |
| Thickness | 1.8-2.2mm | 2-3mm optimal | 2.5-3mm + double wall option |
| Base | 5.5-6cm | 6-7cm | 7-8cm + non-slip surface |
| Guarantee | 1 year standard | 2-3 years | 5 years + replacement service |
| Realistic lifespan | 2-3 years of weekly use | 5-7 years old | 8-10 years with maintenance |
What budget should I plan for a glass of Irish Coffee in 2025?
Summary: A quality Irish coffee cocktail glass will cost between €10 and €30 each. Buying in bulk is ideal as it offers a lower unit price. As is often the case with tableware, a well-designed, high-quality glass will always be a bit more expensive, but this option can be worthwhile.

How to effectively clean an Irish Coffee glass?
Summary: The Irish Coffee cocktail is composed of several layers of ingredients: sugar, coffee, and cream. This makes cleaning important to prevent your cocktail glasses from losing their color and the aromas from being spoiled by residue from the previous drink. Dishwasher use is certainly possible, but hand washing is always recommended, just as with a port glass .
The Irish coffee cocktail is a dishwasher's worst enemy because it requires thorough cleaning. The tannins in the coffee can darken the glass, making it opaque. The sugar in the cream can also cloud the glass, obscuring the glass's transparency and obscuring the layers.
3-step handwashing protocol (recommended):
Step 1: Rinse immediately at 50°C (within 5 minutes)
It's always recommended in the world of tableware to quickly soak your cocktail glasses after each use. Simply add hot water to the inside of the glass and let it soak. If done at the right time, this action removes 65% of the residue before it dries and hardens.
Effective products: Rainett degreasing dishwashing liquid (98% natural), Seventh Generation (fragrance-free), or Marseille soap flakes (10g/litre)
Step 2: Gentle rubbing in circular motions
Once you've rinsed your glass, you can now use a sponge (the soft side). Then, apply the cleaning techniques using a circular motion, pressing gently. Since the bottom of the glass is deeper, this is where the cream and sugar from the coffee tend to accumulate, so you'll need to be careful and clean it thoroughly.
Prohibited: Green scouring sponges, steel wool, hard brushes that irreversibly scratch the dishes.
Step 3: Immediate vertical microfiber drying
Wipe your glasses immediately with a microfiber cloth. Never store a glass while it's still damp, as it will take longer to dry and will develop an unpleasant odor that can linger and mask the aromas during your next tasting experience.
Crucial: If the deposit is too stubborn, you will need to use the cleaning beads for the carafes. These are special beads that won't scratch the surface but will scrape it away and remove the deposits.
Effective natural products for targeted stain removal:
| Natural product | Specific action | Instructions for use | Efficiency |
|---|---|---|---|
| Baking soda + hot water | Powerful stain remover of coffee tannins | Soak for 10-15 minutes in a solution of 2 tbsp/litre of water at 55°C | 95% removal of dark spots |
| White vinegar diluted 50% | Anti-limescale + degreaser | Spray, leave on for 5 minutes, rinse thoroughly. | 100% limescale dissolution |
| Soda crystals | Intensive descaling (caustic, gloves required) | Solution 1 tbsp/liter, soak for 10 minutes max | Professional descaling |
| Lemon juice | Natural acidity, anti-greasy film | Rub half a lemon on the sides, leave for 5 minutes, rinse | Restored shine, fresh scent |
Dishwasher: strict precautions required
✅ ALLOWED only if:
- Robust single-walled borosilicate glass, certified "dishwasher safe"
- Check manufacturer's instructions to confirm compatibility
- Delicate program 50-55°C maximum (never intensive 65°C+)
- Place the upper basket with a minimum spacing of 5cm between glasses.
- Angled 45° orientation for optimal drainage
❌ ABSOLUTELY FORBIDDEN for:
- Double-walled glass: risk of thermal vacuum rupture and delayed implosion
- Decorated, engraved, painted glass: irreversible alteration of the designs
- Models without explicit dishwasher certification
How to store and care for your glass to maximize its lifespan?
Summary: It's not something you necessarily think about when buying a cocktail glass or a whiskey glass , but you'll need to store it. And as we've seen, a glass for an Irish Coffee cocktail is quite large. They therefore need space not only to store them but also to prevent them from clinking together.
Rules for secure storage and preservation:
Optimal position and spacing
It's simple, always put away your glasses for making cocktails or a hot drink.
Store them vertically because it traps moisture. Therefore, they should be stored with the opening facing upwards. We recommend leaving a small space between each glass to prevent it from breaking.
Ideal support: If you have a vertical storage rail designed for bars or restaurants, you can use it. Keep in mind that these items are relatively heavy, so you'll need a reinforced support. This type of storage will save space (also suitable for coffee glasses or other items) for your set while allowing for good ventilation and quick, shock-free access.
Recommended frequency of preventive maintenance
| Frequency | Maintenance actions | Duration | Objective |
|---|---|---|---|
| After EACH use | Wash immediately according to the 7-step protocol, dry completely, store in space | 5-8 min/glass | Prevention of encrustations and odors |
| Weekly (if used frequently, 2x+/week) | Microfiber polishing for maximum shine, visual check for transparency | 2 min/glass | Professional aesthetic maintenance |
| Monthly | Prophylactic descaling with white vinegar, even without visible traces | 15 minutes for 4-6 glasses | Prevention of invisible limescale buildup |
| Quarterly | Checking for cracks with a flashlight (black background, light passing through reveals cracks invisible to the naked eye) | 10-minute complete inspection | Early detection of embrittlement, thermal safety |
| Annual | Thorough cleaning with bicarbonate to remove micro-residues accumulated in microscopic pores | 30 min intensive cleaning | Regeneration, transparency and olfactory neutrality |
Signs of dangerous wear requiring immediate replacement:
🚨 Replace IMMEDIATELY if you observe:
- Multiple deep scratches: More than 5 scratches visible under raking light on the walls. The scratches concentrate thermal stresses and become priority failure points.
- Areas of altered transparency: Localized whitening, milky appearance that does not disappear with cleaning. Sign of devitrification = irreversible molecular aging
- Apparent thermal fatigue: Lenses that "ring" differently upon light impact, a dull sound instead of crystalline. Change in structural density due to repeated thermal cycles.
Realistic lifespan depending on use and maintenance:
| Frequency of use | Rigorous maintenance | Standard maintenance | Neglected maintenance |
|---|---|---|---|
| Occasional (1-2x/month) | 10-15 years old | 8-10 years old | 5-7 years old |
| Regular (1x/week) | 7-10 years old | 5-7 years old | 3-4 years |
| Frequent (2-3 times/week) | 5-8 years old | 4-5 years | 2-3 years |
| Intensive professional (daily) | 3-5 years | 2-3 years | 1-2 years |
Conclusion
If you're not yet a whipped cream pro or your presentation layers aren't perfectly even, stick with an inexpensive practice glass. But once you've mastered the recipe and the ingredients and temperature, you can treat yourself to a more expensive, stylish set for preparing cocktails the old-fashioned way, of course.
