One of the occupational hazards of Cocktail Wonkdom is an insatiable desire to find the next great bottle, the big score, the one you've only heard rumors of. After you've tapped out your local stores and have become bored (or frustrated) by what you can order online, how do you feed the desire? The simple answer: Travel. The moment that Mrs. Wonk purchases our tickets for our next great destination, domestic or international, I’m already plotting a strategy to maximize the goodies we’ll return home with in overstuffed (but, of course, under 50lbs/23kg) suitcases. I've learned a lot along the way, and I’m going to share my hard-won wisdom here.

By this point in our travels, Mrs. Wonk knows that when I suddenly stop dead in my tracks or reverse course, my liquor radar has gone off -- be it an unmarked basement shop in Glasgow, a wholesale store in Barbados, or a bodega in Buenos Aires. Mrs. Wonk has called me at home from a liquor store in Amsterdam and read off liquor bottle labels while I scrambled to Google them and make a yes/no decision. She muled home seven bottles herself that trip. No opportunity squandered!

I think about travelling booze acquisition in four basic parts:

First off, consider why you’d want to bring booze home. It’s kind of a pain, especially if you’re flying to your destination and try (like we always do) to avoid checking bags whenever possible. Bringing even a single bottle back home obligates you to check the bag and wait for it, as airlines clearly don’t allow you to bring aboard liquor in any appreciable quantity, unless it happens to fit in your zip-top baggie. Of course, if travelling by train or car, this is much less of an issue, but for this discussion, I’m assuming air travel and all the modern-day glory it entails.

For me, there are two reasons I’ll buy liquor on a trip:

Liquors I can’t get at home are the vast majority of what I seek out. Here in the United States we have a fairly decent selection of liquor that’s imported from other countries, but there are plenty of great brands without US distribution.

As for spirits that are less expensive than at home, know how much you need to save to make it worth your while. I personally need to save around US $30 before I’ll even consider giving up one of my limited suitcase slots for a bottle I can get at home. A prime example of this was the liter of Mount Gay Extra Old I got for US $25 at the distillery in Bridgetown, Barbados—available locally at $45 for a 750 ML bottle.

It should go without saying, but know your targets. Obviously if you’re a Scotch whisky connoisseur headed to the U.K., it’s a safe bet to focus on Scotch. Ditto for pisco in Peru or mezcal in Mexico. And if you’re the adventurous type, don’t forget to seek out lesser known, local spirits. On our trip to Buenos Aires, I was on the hunt for Argentinian bitter liqueurs, of which there are many high quality examples such as Hesperidina and Pineral.

On our recent trip to London I focused on rum rather than whiskey – England after all was one of the primary importers of rum from the Caribbean as far back as the 1600s, and the English affinity for rum continues to this day. I lost track of how many brands I found in London that aren't available in the US, such as XM and Bristol Classic Rums. A similar situation exists in France, which imports tons of agricole-style rum from its former colonies in the Caribbean. In short, the more you know about the breadth of what’s available at your destination, the better you can optimize your results.

At this point, you should have a good idea what you’re looking for. The next step is researching and planning as much as you can in advance, saving precious time at your destination.

First task: Find an initial set of stores, distilleries, or other destinations to visit. For stores, I can usually find several solid candidates by searching for phrases like “best liquor store Buenos Aires” and browsing through the results to find which names pop up most frequently. Advanced tip: Sometimes the best spirits selection is found in stores that promote themselves primarily on the wine side of things.  (Our best retail score of Buenos Aires was from a wine shop called Malambo Vinoteca Y Almacén Criollo who also had a small if exceptionally well-stocked spirits selection and great enthusiasm for all things local and Argentine.) If you happen to have a friend who knows the area you’re visiting, ask for suggestions. During our London trip, Peter Holland of The Floating Rum Shack pointed me toward two stores I likely wouldn't have found otherwise.

Wonk alert:  As a longtime software engineer, I also find it helpful to pin these locations onto a Google Maps layer I've created for the trip. This helps me figure out opportunities to visit a store while I happen to be nearby for some other planned activity.

If you’re planning on buying spirits in categories that are available at home, such as whiskey, rum, gin, and so on, I find it helps to a have a solid idea of the specific spirits already available to you. It’s a real downer to cart home a really unique looking bottle, only to find that it’s on your local liquor store shelf, but you've never noticed it.

For a category you know well (for me, it’s rum), you probably already have a good sense of whether a given bottle is a keeper. For categories you’re just exploring, I find it useful to visit a couple of online sites with extensive selections (High Time Wine Cellars and DrinkUpNY are my usual two) and save a copy of the available spirits they sell (e.g. gins) to a PDF file or application like OneNote that’s readily available on my smartphone. (I’m a big user of OneNote for keeping track of my spirited adventures and have posted about it previously.)

Ideally, you won’t require internet access to view your saved lists. When I’m on the trip and asking myself, “Can I get the Edradour 10 at home?” I can pull out my smartphone and have a reasonable chance at a correct answer. If you have good internet access on your mobile device, sites like wine-searcher.com and 1000corks.com do a respectable job of searching across numerous online retailers. 

Assuming your goal, like mine, is to maximize the number of bottles you bring back, it’s useful to do reconnaissance missions of stores early in your trip, without buying anything. (I often do this while Mrs. Wonk is at a museum or shopping for shoes.  It’s a win-win situation.)  The goal is to see what’s available, which stores have the best selections and prices, and establish a core set of bottles you’re highly likely to bring back.

Let’s say you can get eight bottles in your suitcase (more on this later) and you know there are five bottles on the “must have” list – it means that you have room for three more bottles that you can select spontaneously as the occasion arises.

During this survey, take notes of the bottles you’re considering. If the situation allows, snap photos of the bottles and prices of anything that looks interesting. If time allows before you depart, research the bottles and come to a solid decision of which to purchase. Doing this in London really saved the day for me. There were easily thirty bottles I wanted, across three different stores, and I needed to narrow it down to no more than twelve. Once I did my homework, Mrs. Wonk and I returned to the stores, shopping list in hand, and did the actual purchasing in short order. The subsequent Uber ride across London early on New Year’s Eve with over $700 of liquor at our feet is a tale for another day.

Although you may already have a list of stores before arriving, take advantage of local knowledge. Several times we've chatted with friendly bartenders on our trips and been pointed to a great store we weren't aware of. A particularly great example was in Vienna, where a bartender at Loosbar told us about Grand Whisky, which not only had a fantastic whiskey collection (even some from our home state of Washington), it also had a seriously impressive collection of rums I thought I’d never see.

What about distilleries? I’ll never pass up a distillery tour (just ask Mrs. Wonk), but to be honest, I frequently leave a distillery empty handed. Surprised? Consider this: At the Mount Gay distillery in Barbados, I found their top of the line 1703 rum for around US $100. However, I knew I could pick up the same bottle online back home for around $80. A similar story at Barton(Ridgemont Reserve) in Kentucky, and ditto for the Auchentoshan in Scotland and St. George Spirits in Alameda, CA. The reality is that most distilleries don’t offer any discount on their mass market products. They’re catering to the casual tourist who’s excited to buy what they just saw being made. Odds are you can find the same bottle at a nearby store for less.

When I do pick up bottles at a distillery, it’s either a bottling that’s not exported to the US or it’s a distillery exclusive and/or limited release bottlings. A few years ago, I was super-excited to pick up several bottles at St. Nicholas Abbey because at the time they didn't export to the US. Likewise, at Heaven Hill in Bardstown, KY, I acquired a bottle of Heaven Hill Select Stock, exclusively available at their gift shop.

When travelling internationally, you may be able to take advantage of Value Added Tax (VAT) refunds on your liquor purchases. For example, in London all my spirits included a 20% VAT tax. If the store offers a VAT refund (and not all do), they’ll refund this money to you after you've left the country. To claim the VAT refund, the store personnel fill out a form which they then present to you. When you leave the country  (e.g., at the airport), a customs official will (in theory) inspect your items and stamp the form, which you then mail back to the store for them to issue your refund. It can be a cumbersome, error prone process however. During our recent London departure, there weren't any agents at the customs station prior to baggage check, and after clearing security it was a mad dash to our plane, so no VAT refund for me.  (On the flipside, Mrs. Wonk’s experience with the VAT refund at Schiphol Airport in Amsterdam was as pleasant as both the rest of the airport and the country itself.  A short wait in line, a few rubber stamps, and they gifted her with a handful of refund cash on the spot.)

Another pro tip:  If you’re in the market for locally made spirits, don’t pass up the grocery store as a great shopping option! Mrs. Wonk and I love a good exploratory stroll through grocery stores in a foreign country – there are always crazy (to us) things we find (though we expect the same could be said of a foreign traveler visiting our own supermarkets). Often, grocery stores carry a decent collection of locally made spirits. Local markets in Buenos Aires offered numerous Argentine bitter liqueurs, including passable Fernet Branca competitors for US $4 per liter—great for Fernet and Cokes in the hotel room. In a supermarket in a residential area of Istanbul, we found lots of inexpensive raki, as well the Hare line of liqueurs, including rose, coffee and sour cherry flavors. Great for gifts if not stocking your own shelves.

A final note when selecting your bottles: Be aware that some airlines restrict the alcohol content of a spirit flying in their cargo holds. The number I commonly see is 75% ABV, or 150 proof. So think hard before you plunk down your money for that bottle of 151 proof rum or 160 proof Stroh from Austria. I brought some Stroh back from Vienna on our last trip, but I made sure it was the 120 proof version—a rarity not readily available in the US.

It’s the last day of your trip. You’re looking at table covered in bottles and wondering how to get it all home in one piece. Between our two standard “fits in an overhead bin” rolling suitcases, Mrs. Wonk and I have consistently been able to bring fifteen or more standard sized bottles home, and so far (fingers crossed!) have not lost a bottle yet. And yet when we pack at home prior to departing for our holiday, both our suitcases are stuffed with clothes and shoes. What’s the trick?

Obviously your bottles need to go into your suitcase so that they can fly as checked luggage. And you’re going to want to wrap the bottles well to protect against the rough-and-tumble baggage experience. This is a Mrs. Wonk Area of Expertise:  First, organize bottles by size and weight, splitting them between the two bags (if you have two).  Think about organizing bottles in two layers—three across on the bottom (where the wheels are), and two or three inverted at the top, with the necks (the most fragile part of the bottle) toward the center of the suitcase.

 Lay down a moderately thin layer of clothes on the bottom of the suitcase, to protect against the usual retractable handle frame inside. Using some of your clothes, wrap each bottle well. (T-shirts work really well for this.) No need to overdo it though. Next, arrange the wrapped bottles loosely together in the suitcase, keeping them from around the edge. Once the bottles are situated, tuck other small clothing—t-shirts, socks, unmentionables—snugly into whatever empty space remains. Top this layer with a section of “tougher” clothing—jeans, pants, sweaters—and then repeat the process with another layer of bottles across the top. The end result once zipped should be snug but not super firmly packed.  Don’t forget that most carry-on bags have an expansion zipper at the front—a no-no when carrying-on and trying to shove it in the overhead compartment, but ideal when you are checking the bag and looking for a few extra inches of room for your bounty.

Next, if you have anywhere close to seven or more bottles in the suitcase, weigh it. We bring a small hand-held travel scale to reduce any potential struggles at the check-in desk. Your goal is to not exceed 50 pounds/23 kilograms; above that, many airlines start charge a higher fee, even if your first checked bag is free. If necessary, remove items to make each suitcase less than 50 pounds.

Unless you packed very lightly for a frolicky beach vacation, you've probably got extra clothes, shoes, and so on that remain to be packed. This is where Mrs. Wonk’s secret weapon comes in:  A lightweight, nylon zip-out bag. (Mrs. Wonk highly recommends the Baggallini Large Zip-Out Shopping Bag—it zips down to a compact 8”x8” size on the way to your destination.)  Fill it with your remaining items, plus any last minute items acquired between now and getting on the plane. This is now your large, but allowable carry-on.

You may be all set at this point, but there may be one more booze acquisition opportunity if you’re traveling internationally: Duty Free. However, duty free liquor isn't the panacea some people believe. In my experience, most of the available inventory is from the big players and readily available anywhere. Sure, you may get a decent price on a bottle, and frequently duty free bottles are 1 liter, as opposed to the 700 or 750 ml bottles you normally see, but is the savings really worth the effort? That's for you to decide. 

Sometimes there are “travel retail exclusive” bottles, frequently as a way to test a new spirit with a (presumably) upscale crowd, i.e., international travelers. Many duty free chains show their inventory online, so you might be able to find out in advance if there’s anything of interest.

If you do buy something at Duty Free, beware that getting it home may be an additional challenge, especially if you have a layover prior to your final destination. When you purchase from duty free, you've already checked your bags before going through security, so you’ll need to hand-carry these bottles home—not a problem if you land in your home city. However, if you have a connection or a layover after an international flight, you’ll need to go through security again, and if so, you won’t be allowed through with your duty free bottles in hand. You will also have to claim your baggage at the layover and recheck it. If this is the case, and you have room in your checked bags, you’ll have an opportunity to stash the bottle in your suitcase, assuming there’s room and you’re not rushing to board your next flight. You roll the dice, you take your chances.

(Update: Commenter Chris points out that TSA regulations now allow you to carry-on duty free purchased liquor as long as it's in a secure, tamper-evident bag and in a transparent bottle.)

And finally, Customs. Many people have the mistaken belief that they can only bring a certain amount of liquor (a liter in the US), through U.S. Customs and Border Patrol when returning home. However, the limit is simply the amount you can import free and clear of customs taxes. If you import more than that, you can pay the duty owed. Several sources on the web say it’s at most $3 per bottle. Obviously this might change, and I’m not providing any sort of legal advice here, but at $3 per bottle, it’s hardly worth passing up the great finds overseas.

When we travel, we always declare all our purchases, including liquor. We've always been prepared to pay the duty owed, but so far (fingers crossed) we've never been asked to pay. Realistically, the duty on our 10 liters of liquor is small enough that it’s likely not worth an agent’s time to deal with it. Obviously your mileage may vary.

Building your liquor collection while travelling can be an enjoyable pastime and provide you with plenty of great spirits and stories to share with your friends back home. It can also give you a “mission” during your trip, if you’re the type that enjoys that, like I do. If you've got your own insights and experiences, drop them in the comments!
