Some time ago I looked at using an aroma kit to help improve my ability to pick out and identify aromas in the spirits that I drink. You can buy an aroma kit but those tend to start around $150 and go up to $450, which is a bit steep for me. And, given the fact that some of the customer reviews are less than stellar, I decided to try and make my own kit. I ended up making 13 bottles with common gin botanicals all for less than $30!

After letting the botanicals to macerate for a month of so, the aromas were still clear but I did notice one issue. While I only filled the bottles 2/3 with botanicals, some of the more fibrous botanical like cardamon, anise seeds, and licorice root absorbed a lot of the vodka and swelled to completely fill the bottle where as more woody botanicals like cinnamon and star anise stayed the same size. So if you make your own aroma kit, make note of which botanicals might be more absorbent than others.

Besides this absorbency issue, the aroma samples worked well. From time to time I would sit down with the bottles, unscrew the lid, and smell the aroma moving the opening back and forth between each nostril.

Being able to pick out and describe aromas in spirits has a lot to do with memory. Our eyes or ears take in information from specific wave lengths of light or sound and those are interpreted by our brains as colors and pitch. But with smell, little particles of the things we eat, drink, or inhale, touch receptors that extend from the olfactory bulb in our brain and we interpret that information based on our memory. It is believed that this link between smell and memory helps humans to avoid eating spoiled food or drinking contaminated water. And, this smell memory may have helped our hunter-gatherer ancestors to remember high calorie foods like fruits that are higher in natural sugar and vitamins.

In my experience, interpreting aromas exists on three levels.

1. Is the aroma good or bad?

2. Is the aroma familiar or unfamiliar?

3. Can I describe or name the aroma with a word or words?

I believe using my kit did help me move some of the aromas from the second level of, is it familiar to the third level of, it is familiar and I my brain remembers the name of that smell. If you are interested in improving your smell memory, making and occasionally using a spirits aroma kit will help.

DIY Spirit Aroma Kit: The First Batch

Supplies for the aroma kit.​

A little while ago I went to Rainbow Grocery which is a local CoOp to pick up some herbs and spices for my Spirit Aroma Kit. I took the 2oz amber glass bottles and filled each one about two-thirds full. I have been editing a book about gin so some of the herbs I picked were inspired by common gin botanicals. I bought Angelica Root, Anise Seed, Ceylon Cinnamon, Cilantro, Green Cardamom, Juniper Berry, Lavender Flower, Lemon Grass, Licorice Root, Orris Root, Star Anise, Vietnamese Cinnamon, and Whole Black Peppercorns. The total cost for the thirteen herbs and spices was less than $10 which is a positive sign that my kit will be significantly less than the commercial kit.

Next I got my herbs together, pulled out my bottle of vodka, a small funnel and some small white labels. For each bottle I measured out 2oz of vodka and using the funnel, poured it into the bottles up to the neck. On the label I wrote the name of the herb or spice, the date, weight of the contents and volume of vodka. After I applied each label I gave the bottles a shake to make sure the vodka saturated all of the contents. Once each bottle was labeled and shaken I placed them in one of my kitchen cabinets to steep.

First batch of aroma bottles

Based on what I've read about tinctures this steeping process can take up to six to eight weeks to reach its full potency. In the mean time I am going to get more herbs as well as some grains from the my local homebrew store, San Francisco Brew Craft and fill some more bottles.

DIY Spirit Aroma Kit

Last year the Commonwealth Club of California hosted a panel discussions entitled “Distilled in the Bay Area: How to Drink Like a Locavore.” During the Q&A, one question that seemed to be on the minds of many in the audience was, how to improve one's ability to detect and describe the aromas present in spirits? The panel of distillers offered a few suggestions. Their primary suggestion, which I've heard before, was to hold a tasting with some friends. At the tasting you pick a couple spirits of the same type (i.e. gin, bourbon, scotch, rum) and as you smell and drink them you talk with your friends about the aromas and flavors you are noticing. It is helpful to do this in a group because not only will different people notice different things but they may also use different words to describe whats in the glass. I can say from my own experience these types of events are very helpful. Numerous times I have had an experience where I have been stuck trying to describe an aroma and a friend offers their suggestion which perfectly describes the sensation.

The second suggestion the panel offered to improve one's ability to recognize aromas was to practice with an aroma kit. An aroma kit is a collection of small vials that contain aromatics that match the name on the label. For instance vials labeled oak, green apple, black cherry, clove, smell like their name. The purpose of these are to practice associating the smell of an aroma with its name so that when you come across a similar aromas in spirits you can identify them. However, the only commercially available aroma kits I was able to find were geared towards red wine drinkers and very expensive. I was primarily interested in aromas found in spirits and I not that keen to spend hundreds of dollars on a kit that some reviewers complained came with vials that didn't smell at all.

I was almost ready to give up on the idea when my brain connected a conversation I had with a friend about herbal tinctures with my homemade vanilla extract. A number of years ago some friends gave me a vanilla extract kit for Christmas. The kit consisted of a 4oz bottle three whole vanilla beans and a bottle of vodka. To make the vanilla extract I slit the beans, placed them in the bottle, filled it with vodka and let it sit in the cupboard. Since alcohol is a solvent the vodka dissolves a little of the vanilla bean infusing it with its flavor and aroma. Tinctures are similar in that they use alcohol to extract healthful properties from various herbs. I put these together and I thought maybe I could make my own spirits aroma kit.

To do this I bought some 2oz amber glass bottles with the plan to fill them with various herbs, spices, other aromatics common to spirits and 40% vodka and see what happens. Future posts in this series will show my process, the results and hopefully prove to be a low-cost alternative to buying a commercial aroma kit.
