Most lists of tequila accessories are a catalogue with a headline on it. This one is shorter, because very little actually changes what is in your glass. I keep records on 87 tequilas, 36 of them bottles on my own shelf across 24 distilleries — and in that time exactly three things have made a measurable difference: the glass, how the bottle is stored, and writing down what was on the label before the bottle is gone. Everything else on the usual list is decoration.

The shot glass is not a mistake. It is a different drink.
The caballito — the tall straight shot glass — gets treated as the villain of tequila writing. It is not. It was designed for a specific ritual: a pour of tequila alongside a pour of sangrita, sipped in alternation, which is how tequila is drunk across much of Mexico and has been for a century. For that, it is exactly right.
It is only wrong for one job, and that job is assessment. Straight sides let aroma rise and leave. A bowl that narrows toward the rim collects it and holds it where your nose is. Since aroma carries most of what you experience as flavour, the glass decides how much of the bottle actually reaches you. Use a wine glass from the cupboard before you use a caballito to judge a tequila.
What a tasting glass has to do
Three requirements, and one habit that matters more than any of them:
- A rim narrower than the bowl. This is the whole mechanism. Everything else is refinement.
- A stem, or somewhere to hold it that is not the bowl. Hand heat drives off the light aromatics first — the citrus and cooked-agave notes — and leaves the heavy ones behind. Holding the bowl quietly changes the drink.
- Thin, clear, uncoloured glass. Colour is real information in tequila: it separates a blanco from a reposado, and it is the one thing a cristalino has had removed. Tinted glass hides it.
- And do not chill it. Cold suppresses aroma. A $200 añejo served cold performs like a $30 one, which is sometimes the point and is usually an accident.
The glasses, compared honestly
| Glass | Shape | What it is for | What it shows you |
|---|---|---|---|
| Caballito (shot glass) | Straight sides, no stem, thick glass | Tequila with sangrita, or a toast | Nothing — aroma leaves as fast as it forms |
| Copita / catador | Narrow rim, wider bowl, short stem | Tasting anything you paid attention to | Everything — this is the default |
| Glencairn | Tulip bowl, squat stem, heavier base | Aged tequila, and anyone who already owns one for whisky | Almost everything |
| Riedel agave glass | Long tapered bowl on a tall stem | Blanco especially | Everything, at a price |
| Wine glass | Whatever is in the cupboard | Right now, for free | More than a shot glass |
| Snifter | Wide bowl, short neck | Brandy | Too much surface — alcohol dominates the nose |
If you buy one thing, buy a pair of copitas — the small stemmed tasting glasses, also sold as catadores. A pair rather than one, because the single most useful tasting exercise is two glasses side by side: a blanco and a reposado from the same distillery, where the only variable is time in oak. How to run that tasting.
If you already own a Glencairn for whisky, you do not need to buy anything at all. It is not the ideal shape for blanco — the bowl is a little generous, so the alcohol arrives before the agave does — but it is far closer to right than anything else in a normal kitchen.
What not to buy
This section costs me money, which is roughly the point of it.
- Coloured hand-blown Mexican glassware. Genuinely beautiful, often hand-made, and it breaks two of the three requirements at once: tinted glass and a thick wall. Buy it because you want it on the table. Do not buy it to taste from.
- Flight and tasting sets. Usually four or six novelty-shaped glasses on a wooden paddle. Palate fatigue means three or four pours is the honest limit anyway, and the glasses in these sets are chosen to look like a set rather than to work.
- Whisky stones, and anything sold for chilling. See above: cold is what you are trying to avoid.
- Aerators. Tequila is not a young red wine. Thirty seconds in the glass and a drop of water at 43% and above does everything an aerator claims to.
- Decanters, for anything you plan to drink. A decanter is a display object. The more time a spirit spends with air and light, the less it resembles what you bought.
The accessory nobody sells: a bottle log
The most valuable thing I own for tequila cost nothing. It is a record of every bottle, and it is the reason I know things about my own shelf that no listing would have told me.
An example. Four of the most expensive-looking bottles I own — ceramic, painted, weighted, gift-grade — are bottled at 35%, the Mexican legal minimum. The plain screw-cap bottle beside them is 54%.
| Bottle | Presentation | Alcohol |
|---|---|---|
| Código 1316 extra añejo | Hand-painted ceramic decanter | 35% |
| Mundo de Oro añejo cristalino | Smoked-glass decanter | 35% |
| Don Ramón Platinium | Metallic-finish bottle | 35% |
| La Cuerda añejo | Embossed glass | 35% |
| G4 108 | Plain bottle, screw cap | 54% |
Alcohol carries aroma, so the costly bottles are the quiet ones in the glass. I did not read that anywhere. It fell out of a spreadsheet. The full range, and where each bottle sits.
Four fields do all the work, and all four are on the bottle in front of you:
- The NOM — four digits naming the distillery that actually made it. Brands move production; two bottles of the same brand on my shelf carry different NOMs. Look one up.
- 100% de agave, or not — the single most useful line on the front.
- The alcohol figure, and which market the bottle came from — my Don Julio reads 38% because it was bottled for Mexico; the US bottling of the same expression is 40%. Record both or the note contradicts itself later.
- Any stated age — “2 meses” and “eight months” are both legally reposado.
A notebook works. A spreadsheet works better, because six months later you can sort it and notice that the two bottles you liked best came out of the same building. Where each of those four fields sits on the label.
Storage is an accessory decision too
Tequila does not improve in the bottle. Aging happens in oak and stops the day it is bottled, so nothing you buy is quietly getting better on the shelf — but it can quietly get worse. Upright, always, because unlike wine, tequila’s alcohol degrades a cork lying down. Dark and cool. Away from the window the bottle looks best in. The full storage guide.
Which makes the honest storage accessory list very short: a cabinet with a door. Anything sold as a display stand is asking you to do the one thing that damages the bottle.
Sangrita, and the glass that is right for it
The one case where matched caballitos are exactly what you want. Sangrita is served beside the tequila, not mixed into it — traditionally tomato, citrus and chilli, though the older Jalisco version is closer to pomegranate and orange with no tomato at all. Two equal pours, alternating sips. Nothing about that needs a stem or a narrowed rim, and a matched pair on the table is part of the ritual.
It also does something a tasting glass cannot: it makes a mid-range blanco genuinely pleasant to drink for an hour. The original sangrita recipe — which, before 1957, contained no tomato at all. That is a different goal from assessment, and worth keeping separate in your head.
Tequila accessories: quick answers
Can I just use a wine glass?
Yes, and you should, before spending anything. A white wine glass has a narrower rim than its bowl and a stem — both requirements met. It is a little large, so give it a smaller pour and a minute to settle.
Is an expensive tasting glass worth it?
The jump from a shot glass to any stemmed glass with a narrowed rim is enormous. The jump from a $10 copita to a $40 designer glass is small and real. Spend the first ten dollars immediately; make the second decision after a few months of tasting.
Does the glass actually change the taste?
It changes what reaches your nose, and your nose is doing most of the work your tongue gets credit for. Pour the same tequila into a caballito and a copita side by side and the difference is not subtle — it is the clearest demonstration of the whole idea, and costs you one extra pour.
What about a decanter?
Fine as an object, poor as storage. Light and air are the two things that change an opened bottle for the worse, and a decanter maximises both. If a bottle is beautiful enough to display, display the bottle.
Do I need a specific glass for a margarita?
No. The classic coupe or a rocks glass are both fine, and neither affects the tequila much once there is lime and orange liqueur in it. Save the glassware thinking for what you drink neat.
