Running a vertical tasting of the same beer across several years

What a vertical tasting is

A vertical is a set of the same beer released in different years, tasted together. A horizontal is different beers of the same style from the same year. The vertical isolates time as the main variable, so whatever differs between glasses is mostly the result of ageing.

Recipes and batches can vary from year to year, so treat the result as a guide, not a lab experiment. But the broad pattern of ageing usually comes through clearly.

You do not have to wait years to start. Buy several bottles of one strong beer now, open one straight away and write notes. Open the next after six months and another after a year. A home vertical built this way is slower but cheaper than hunting for old vintages. You also know exactly how each bottle was stored.

Which beers are worth ageing

Most beer is best fresh. Only some styles improve or develop interestingly with age. Good candidates are strong, dark and malty beers with high alcohol, often 8% and above:

• Barleywines, both English and American. Our guide to barleywine covers the style.
• Imperial stouts, especially barrel-aged ones.
• Belgian strong dark ales and quadrupels.
• Old ales.
• Some sour and wild ales, such as gueuze-style blends.

Avoid hoppy beers like IPAs, pale lagers and wheat beers. Their fresh hop and yeast character fades quickly. Age rarely adds anything good.

Cellaring beer in Indian conditions

Ageing requires stable, cool storage. The traditional target is around 10 to 15 °C, dark and steady. Few Indian homes have a cellar that cool. Room temperature in much of the country sits well above that for most of the year. Warm storage speeds up staling and can produce harsh, cooked flavours.

A practical option is a dedicated beer or wine fridge set to around 12 °C. If you only have a regular fridge, it is better than warm storage, though ageing will be very slow. Keep bottles upright to limit contact between beer and the cap or cork. Keep them in the dark.

Label each bottle with its vintage and the date you put it away. Over a few years, buy one or two bottles of the same beer each release and set them aside.

What changes with age

Our guide to beer staling chemistry explains the reactions. In the glass, you will typically notice:

• Hop bitterness and aroma fade. Older vintages taste softer and sweeter.
• Oxidation notes develop. Sherry, port, dried fruit, toffee and honey. In moderation these can be lovely in a barleywine. Wet cardboard or papery notes are less welcome.
• Malt flavours deepen. Caramel turns to toffee and treacle, sometimes with notes of leather or tobacco.
• Alcohol integrates. Hot, sharp alcohol in a young beer can soften and blend in.
• Carbonation drops. Older beer often pours with less fizz and a thinner head.
• Colour darkens. Older beer often looks a shade darker and sometimes hazier.

Running the tasting

Choose three to five vintages. Chill all bottles to the same temperature, around 10 to 13 °C for strong beers. Open them together and pour small samples, around 50 to 60 ml, into identical glasses. Label each glass with its year.

Taste from youngest to oldest first, then go back and taste in reverse. The youngest beer shows the baseline. Each older glass shows what time has added or taken away. Taste each one several times as it warms. Our guide to setting up a beer tasting covers the table setup.

Then decide which year you prefer and why. Most groups find a sweet spot, a vintage old enough to have softened and gained depth but not so old that it has faded or turned papery. That sweet spot is useful to know if you plan to keep buying the beer.

Keep it responsible and keep notes

Strong beers are high in alcohol, so share each bottle between several people and keep pours small. Serve water and plain food. Plan everyone's way home before you begin.

Write notes on each vintage under the same headings: appearance, aroma, flavour, mouthfeel and overall. Keep them with your cellar records. Next year, add the new release and taste again. Telling pleasant ageing from oxidation faults is a real sensory skill, one that structured training with reference samples sharpens quickly.
