Gin might be the most underrated spirit for a tasting party. Every bottle shares one ingredient, juniper, and then goes in a wildly different direction: pine and citrus, cucumber and rose, yuzu and green tea, or soft and lightly sweet. Pour four side by side and even people who "don't like gin" usually find one they love. Then you open a G&T bar and the party runs itself.
What makes gin gin
Gin is a neutral spirit flavored with botanicals, and juniper has to lead. US rules (27 CFR 5.144) say gin must get its main characteristic flavor from juniper berries and be bottled at no less than 80 proof (40% ABV). In the EU, juniper must be predominant and the minimum is 37.5% ABV.
Two label terms are worth knowing before you shop:
- London Dry is a method, not a place. All the flavor must come from real botanicals during distillation, with no added flavoring or color afterward and almost no sugar. Tanqueray is made in Scotland and is still a London Dry.
- Distilled gin vs. plain "gin." Distilled gin is redistilled with its botanicals. A bottle that just says "gin" can be compound gin, neutral spirit mixed with flavorings and not distilled again.
Pick four gins, four styles
A tasting works best when each glass shows a different idea of what gin can be:
- London Dry. The baseline: dry, piney, crisp citrus. Beefeater, Tanqueray or Bombay Sapphire.
- Contemporary (New Western). Juniper shares the stage. Hendrick's leans cucumber and rose; Aviation is softer and floral.
- A world gin. Roku from Japan uses sakura, yuzu and sencha; The Botanist from Islay uses 22 foraged island botanicals.
- A historic style. Plymouth (softer, earthier, made in Plymouth, England, since 1793) or an Old Tom, the lightly sweetened style popular in the 1800s.
On a budget, a Newbie flight of Seagram's Extra Dry, Beefeater, Tanqueray and Bombay Sapphire costs well under $100 for all four bottles and still shows real differences.
How much to buy
For the neat tasting, pour about 1 ounce of each gin. A 750ml bottle holds about 25.4 ounces, so one bottle of each covers a crowd easily. The G&T bar is where the volume goes. For 12 guests, plan on:
- 2 bottles of gin (one London Dry, one modern), on top of what's left from the tasting.
- About 24 single-serve bottles of tonic. Small bottles stay fizzier than big ones once opened.
- Two bags of ice, because a G&T needs a full glass of it.

How to taste gin neat
Gin is usually mixed, so tasting it neat surprises people. Pour each one into a small wine glass or tulip glass at room temperature:
- Nose it. Pick out juniper first, then whatever comes next: citrus, flowers, spice, herbs.
- Sip a little and let it sit on your tongue.
- Add a few drops of water. It opens up the botanicals and softens the alcohol.
- Taste it with tonic. A splash of tonic in a second glass shows how each gin behaves in the drink people actually make.
Go from driest and most juniper-forward to the sweetest and softest, and keep plain crackers and water on the table.
Play the Juniper-Off
Bag four gins, number the glasses, and pour them blind. Guests score each gin from 1 to 10, then guess which bottle is which. One point for every correct guess and a bonus point for naming the most juniper-forward gin. The reveal is the fun part: the gin that wins the blind vote is often not the fanciest bottle. For tips on keeping blind rounds friendly, see How to Run a Blind Tasting.
Open a build-your-own G&T bar
Set out the gins with a jigger, then lay out tonics and garnishes and let guests build their own:
- Tonics: a classic Indian tonic, a light tonic, an elderflower tonic and plain soda water.
- Garnishes: lime wedges, cucumber ribbons, pink grapefruit slices, rosemary, basil, mint, a few juniper berries and pink peppercorns.
To build a good one, use a balloon glass filled to the top with big ice cubes, pour 1½ to 2 ounces of gin, then about 2 to 3 parts cold tonic down a bar spoon. One gentle stir is all it needs. Hard stirring kills the fizz.
Keep a zero-proof pitcher on the bar too: a juniper and rosemary syrup with lime, cucumber, tonic and soda gives non-drinkers the same piney, bubbly glass.
What to serve with it
- Smoked salmon and oysters with a dry London gin.
- Salty olives and salted nuts, which also make tonic taste less bitter.
- Cucumber sandwiches for the Hendrick's fans.
- Goat cheese with herbal gins and bright tonic.
- Lemon tart or other citrus desserts to finish.
Quick answers
Do I need to keep gin in the fridge? No. Sealed or open, gin keeps for years on a shelf away from sunlight. It also won't freeze in a home freezer, which is handy for ice-cold martinis.
Is sloe gin a gin? It's a liqueur made by steeping sloe berries in gin with sugar. It's sweet and lower in alcohol.
What does "navy strength" mean? Gin bottled at about 57% ABV or higher. It's a tradition, not a legal category, so pour it small.
Keep it a good night
This is a 21+ party. Use a jigger instead of free pouring, put food out early, alternate with water and plan rides home before the bar opens.
