The post-Brexit personal allowance for wine is 18 litres, which is 24 standard bottles. That is not a practical travel amount, but it tells you the rules are generous. For a city break, you are realistically looking at three to six bottles in checked luggage. Do it properly and none of them will break.

What the Rules Actually Say

Entering Great Britain from any country outside Great Britain, you can bring 18 litres of still wine and 4 litres of spirits duty-free as a personal allowance. Sparkling wine counts separately at 9 litres. These limits apply per person and are for personal use, not resale. Customs officers do occasionally ask, particularly for larger quantities. Having a receipt is useful.

Wine Shops Over Supermarkets

A specialist wine shop is worth it for this specific purpose. Not because the wine is necessarily better, but because you can ask the right questions. Ask what travels well. Ask what needs to drink young and therefore should not make the trip. Ask what is produced locally and unavailable at home. A good wine merchant answers all of these usefully. A supermarket shelf cannot.

Local appellations are the practical reason to buy wine abroad. A Bordeaux superblend is available in Tesco. An obscure natural producer from a smaller appellation probably is not. That is where the specialist shop earns its price premium.

Packing Without Breaking Bottles

Padded wine bags are the correct solution. WineSkin is the most widely available brand. Each sleeve is a plastic bubble that seals around the bottle and, in the event of breakage, contains the spill inside the bag. They are not heavy, pack flat before use, and do the job. Pack bottles vertically in the centre of your checked bag with clothes on all sides.

Do not put wine in carry-on luggage unless you buy it airside. Bottles bought in the departures duty-free zone can go in your hand luggage in a sealed STEB bag. Bottles bought in the city cannot.

What to Ask the Shop

Ask what they would bring home if they were travelling to the UK. Ask what is in the shop that you cannot buy in Britain. Ask whether the bottles you are considering are fragile in transit. Most good wine merchants have had this conversation many times and are helpful rather than precious about it.
