Buying two bottles to taste one now and one in a year

The cheapest experiment in beer

You do not need a cellar or a collection to learn about ageing. You need two bottles of the same beer from the same batch and a calendar reminder. Open one now. Open the other in twelve months. Compare your notes. That is a real experiment with a control. It costs one extra bottle.

We like it because it removes guesswork. Labels and reviews tell you a beer "ages well". Your own two notes, a year apart, tell you whether it aged well in your house at your temperatures.

Pick a beer that can take the time

Choose something strong, dark or alive:

• Barley wine or old ale, often 9% ABV or above.
• Belgian quadrupel or dark strong ale.
• Imperial stout, especially barrel aged.
• Gueuze or a Brettanomyces saison.

For a contrast, add a pair of fresh hoppy IPAs. They will not improve. That is the lesson. A year-old IPA usually loses its hop aroma and picks up caramel and paper notes. Tasting that once teaches you why packaged-on dates matter so much for hop-forward beer.

Write the first note properly

The year-later tasting is only as good as the first note. Serve at a fixed temperature, around 12 to 14 °C for strong ales and 6 to 8 °C for IPAs. Use the same glass each time. Write five short lines: appearance, aroma, flavour, mouthfeel and finish.

Record the packaged-on date, the date you opened it and where you will store the second bottle. Score how much you enjoyed it out of 10. If you keep a sensory journal, put the note there so you can find it in a year.

Store the second bottle with care

Keep it somewhere dark and as cool and steady as you can manage. In much of India that means the coolest interior cupboard, away from outside walls, the kitchen and the top of the fridge. Better still, a wine fridge at about 13 °C. Keep crown-capped bottles upright.

Heat changes the result a lot. A beer kept at 30 °C for a year will taste much older than one kept at 13 °C. That is not a failed experiment. It is the most useful thing you can learn about your own storage.

Make it a small group tasting

The year-later tasting works even better with three or four friends. Different people pick up different things. One will notice the hop fade at once. Another will spot that the body has thinned. Pour small measures of about 60 ml per person per beer, keep water on the table and have food ready. Strong ales add up quickly.

Ask everyone to write notes before anyone talks. Group tastings drift towards the loudest voice in the room. Silent notes first, discussion second, keeps the result honest. Then compare. Where everyone agrees, you have a clear change. Where people disagree, you have found a note worth learning about.

If anyone needs to drive home, they taste and spit or skip the strong beers. Plan the ride before the first bottle opens.

Running the year-later tasting

A year on, serve the second bottle at the same temperature in the same glass. Read your old note only after writing the new one, so the first note does not lead you.

Better still, buy a fresh bottle of the same beer on the day and taste it alongside the aged one. Ask a friend to pour them blind into identical glasses. Now you have a fair comparison of fresh against aged, which is the heart of a well-run flight.

Look for specific changes: hop aroma down, dried fruit up, alcohol softer, body thinner, carbonation different. Write the direction of each change, not just a verdict.

What the pair teaches you

After two or three of these pairs, patterns appear. You will see which styles your storage suits and how quickly beers fade in your climate. You will also start to notice that your vocabulary limits what you can record. "Smoother" and "different" turn up a lot in first-year notes.

That is the gap a structured tasting course fills: learning the reference aromas for oxidation, esters and hop fade so your notes become precise.

Your first step: pick one strong beer you enjoy, buy two bottles this week and set a reminder on your phone for twelve months from today.

Common questions

Which beers are good for a one year ageing test?

Strong, dark or bottle-conditioned beers such as barley wine, quadrupel, imperial stout or gueuze. A fresh IPA is useful as a contrast because it usually gets worse.

Should I taste the aged bottle blind?

It helps. Ask someone to pour the aged bottle and a fresh one into identical glasses so you judge them on flavour, not on expectation.

Where should I keep the second bottle?

Somewhere dark, cool and steady, ideally around 10 to 15 °C. If you only have a warm cupboard, note that in your log because it will speed up ageing.
