Why does the same drink sometimes taste completely different from one day to the next?
It might seem like the wine, beer or spirit has changed but more often, it’s your senses. Subtle shifts in your palate, your environment or even your level of hydration can affect how clearly you perceive aromas, flavours and texture.
Tasting is central to any WSET qualification, but it’s also a skill that improves with awareness and preparation. By creating the right conditions for your senses, you give yourself the best chance of experiencing a drink as it truly is.
Here’s how to prepare your palate for more accurate, confident tasting.
Key considerations for preparing your palate
Ensure you have a clean, neutral palate
Before tasting, your palate should be as neutral as possible. Strong or lingering flavours can mask more delicate characteristics and distort balance.
Before tasting, you should avoid:
- strongly flavoured foods
- toothpaste or mouthwash
- coffee, cigarettes or chewing gum
In short, if it sticks around, it’s not helping.
If needed, a small piece of plain bread can help remove lingering flavours. The goal isn’t to eliminate sensation entirely, but to avoid competing flavours that distract from the drink itself.
This is especially important when tasting subtle styles - such as lighter wines, delicate sakes or elegant spirits - where nuance matters.
You should also have a spittoon at the ready. Tasting five wines is very different from drinking five wines and alcohol itself can quickly start to alter your perception.
Ensure you remain hydrated
Did you know that hydration has a direct impact on your senses, particularly smell?
When you’re dehydrated, your nasal aroma receptors can become dry and less sensitive, making it harder to detect aromas and flavours. So it’s key to stay hydrated before and during, with sips of water throughout your tasting session.
During tastings, dehydration can happen quickly - especially when spitting, as you will be losing saliva each time. It adds up more than you might expect.
Alcohol itself is also dehydrating. When tasting spirits and sake in particular, alcohol vapours can further dry the nose, gradually reducing your ability to perceive aroma over time.
Remove all strong smells
When tasting your space should be free of strong odours like cleaning products, air fresheners, food or tobacco as these can impact your ability to accurately identify aromas and flavours.
It’s not just the room, either. Strongly scented products like perfume or aftershave can follow you into the glass and compete with what you’re trying to assess.
In short, if you can smell it before you start, it’s likely to get in the way once you do.
How your senses shape what you taste
When we talk about “palate”, we’re really talking about several senses working together. Understanding their roles helps you interpret what you’re experiencing more clearly.
Sight: useful, but potentially misleading
Sight is the least helpful sense when tasting many alcoholic drinks - particularly spirits - but it still plays a role.
We naturally rely on visual cues, and the brain quickly forms expectations based on colour and appearance. A deeper colour might suggest richness or sweetness, while a pale tone might signal something lighter or fresher. These assumptions can subtly shape how we perceive aroma, taste and texture before we’ve even taken a sip.
Smell: aroma and flavour
Smell is the most important sense in tasting.
- Aroma refers to sensations detected when you sniff the glass.
- Flavour refers to sensations detected by smell when the drink is in your mouth.
In both cases, these sensations are caused by aroma compounds detected by receptors in the nasal cavity. The tongue cannot detect aromas or flavours.
This is why taking time to smell before tasting is so important, and why a drink can seem muted if your nose is congested, fatigued or simply not fully engaged.
Taste: the role of the tongue in tasting
The tongue is responsible for identifying five tastes only:
- sweet
- bitter
- sour (acid)
- salt
- umami
Taste doesn’t actually tell you what a drink tastes like - only these basic taste components. Which is why we combine so many senses when tasting!
Touch: texture and mouthfeel
Touch is an often overlooked but crucial part of tasting. It includes sensations such as:
- heat or burn
- weight and body
- smoothness, sharpness or mouthcoating texture
These tactile sensations all contribute to how wines, beers, spirits and sakes feel on the palate. No tasting note is complete without considering texture.
Putting all the senses together
In practice, when a drink is in your mouth, you don’t experience taste, smell and touch separately. Your brain combines them into a single overall impression.
Early on, this impression may feel vague - “it just tastes like wine” or “it smells like whisky”. Structured tasting is about slowing this moment down and learning to unpick it. With time and practice, you become better at separating aroma from taste, flavour from texture, and intensity from balance.
Individual sensitivities vary, and personal experience always plays a role. Even so, trained tasters can agree with a high degree of consistency on characteristics such as sweetness, texture or length of finish - a skill that develops through repetition and calibration.
The human factor when tasting
There are some human factors that will impact your ability to taste, which include:
- fatigue
- colds, congestion or hay fever
- stress or lack of focus
It’s worth identifying these factors and taking this into consideration if you’re doing a tasting - your senses may end up playing tricks on you.
Preparing your palate is about giving your senses the support they need to do their job.
A clean mouth, good hydration and a considered approach to tasting allow you to experience drinks more clearly and accurately. When you understand how sight, smell, taste and touch work together, tasting becomes less about guesswork and more about confident, informed observation.
