Your how-to guide for developing world class gin

By Kris Bohm, Distillery Now Consulting
The process of developing a new gin can be a fun trip into the world of flavor and the many possibilities of flavors that can be extracted from unique botanicals through ethanol distillation. While at first the concept of developing gin may seem daunting to a distiller, the process of making a great gin can be simplified by following our handy dandy gin distillation guide.
Before we jump right into the process let’s take a quick moment to go over what gin is and is not. In America gin is traditionally made from a neutral spirit that is redistilled with botanicals to create a flavored spirit that is gin.
A typical gin will have juniper and coriander as its primary botanicals with many other botanicals also adding flavor to the spirit.
In Europe and beyond gin is often a much broader term to define a spirit redistilled with almost any type of fresh botanical or ingredient. There are even some gins that taste more like fresh cucumber than juniper. I find it helpful for a distiller who is looking to make gin to understand the category of gin well, before beginning the endeavor of developing their own. This process of tasting some commercial produced gins made by other distillers is an excellent way to find inspiration for your own gin.
With that said let’s dive right into the process of distilling with botanicals to start your journey with gin. It is important we take a moment to note that home distillation is not legal on a federal level in the United States. As always, if you intend to distill, we recommend doing it legally and that you secure the proper state and federal permits.
For initial product development it is best to distill on a small scale and do concept trials. You can do good product development work with a small lab 1 liter glass still. Glass lab stills which utilize hot plates as a heat source and domestic water for condenser cooling are easy to work with and relatively inexpensive. Glass laboratory stills can be procured with a botanical basket for vapor infusion of botanicals.

For the neutral spirit being redistilled, we recommend a sourced a clean neutral spirit (like vodka or grain neutral spirits) diluted to 40% ABV. It is unsafe to place any spirits in a still higher than 50% so we recommend 40% as a starting point for botanical distillation. It is critical to take detailed notes throughout this process to create replicable results.
The only difference between science and screwing around is taking good notes. So, take good notes though the whole process and you’ll be better able to produce replicable results. Weigh all ingredients, take notes on yield. Take notes on flavors. This process of note taking will be essential as you move further into product development.
The botanicals themselves are essential to the quality of your gin. Not everyone has fresh juniper growing in their backyard, so a distiller often must look to buy juniper from a commercial botanical supplier.
Now, while you can find botanicals quick and easy on Amazon, it is important to talk about freshness and quality. The freshness and overall quality of a botanical is paramount in producing a good gin. Buying botanicals directly from reputable botanical companies will help to ensure you are working with high quality ingredients. Fresh juniper will be soft when squeezed, slightly sticky inside and very aromatic.
If you buy juniper that is shriveled and bone dry, it will likely not make a good gin. Botanicals of all varieties are a seasonal agricultural product. Taking the time to understand the seasonality of some ingredients can help to make the best possible gin. For example, if you are making gin with citrus, it is helpful to buy it and distill it fresh during harvest season.
Distillers frequently contemplate using many different botanicals when crafting a gin. Understanding how each botanical contributes to the flavor of gin is not easy to do.
During product development the best way to develop your palate to recognize botanical influence is through single botanical distillation. This process is in essence placing neutral spirit in your still and adding a single botanical to the still, then distilling the spirit to extract flavor from the botanical. This will yield a spirit that is solely the single flavor of a botanical.
By doing a single distillation of each botanical it will help you develop your product in two ways. First it helps in that you can taste each botanical individually to understand the essence of its flavor. Once you have gained an understanding of flavor you can then work on blending the spirits from your single botanical distillations to create a complete gin. As we get in more detail, we discuss quantities and ratios to give you a starting point for development.
Now that you have a variety of flavored spirits you have distilled via Single Botanical distillation it is time to get into blending. The best starting point for blending is to understand common gin botanical ratios.
In a glass while weighing out your distillates a simple starting point could look like…
60-grams juniper
10-grams coriander
2-grams Angelica
2-grams bitter orange peel
2-grams lemon peel
1-gram orris root
1 gram cardamom
1-gram cinnamon bark
1-gram grains of paradise
1 gram cassia
After you have blended all these individual distillates into a jar, you should take a moment to make sure you have written down all the blending work that created this gin. This newly created gin will need to be diluted to bring the spirit down to a bottling strength. Add a bit of distilled water to reduce the concentration of alcohol.
The ideal concentration is somewhere between 40-50% Alcohol by volume. Your gin is now ready to taste. Taste the gin and consider the overall flavor profile. If some botanicals are lacking, then add a bit more of that botanical distillate to the blend. If a certain botanical is overpowering, then create a new blend with different ratios.
This process of blending and tasting can feel arduous and may take many tries to get just right. It is worth the work to do this blending process. It will not only ensure your gin is excellent but create a solid base to scale up your gin production. Once you have found a blend that you love it is time to scale up the recipe and make a big batch of gin.
Scaling up production can be done in a few different ways. The most common way to scale up is to do what is known as single shot gin distillation. Single shot distillation consists of adding neutral spirits to the still along with all botanicals then redistilling the spirit to create a gin.
After distillation the only thing added to the gin is water to dilute its strength. Determining how much of each botanical to add to the gin should be done using a multiplier based upon the quantities that went into your original blends. It is important to note that all stills behave a bit differently.
You may find that your scaled up gin recipe may differ a bit in flavor from the lab scale recipe. As you have individual botanical distillates you can tailor the gin with the additional of single botanicals to adjust the flavor of the product if adjustments are needed.
The development and creation of gin is a fun endeavor in the world of botanicals. Good gin takes work to create and has the potential to be a great product in your distillery lineup.
