A Distillers Guide to Distillation
One of our principles at 1919 Distilling is to be transparent about how we make our gin, so find a comfy seat pour a drink and settle in as we dive into the step-by-step process.
STEP ONE: THE WASH
First things first we need to make alcohol. To achieve this, we start with a wash/mash. This is done using wheat, corn, barley, sugar or molasses and adding water to make a sweet sugary fermentable liquid.
Once we have our mash or wash, we are ready for the next step, adding the yeast. Yeast is one of the most essential ingredients, and to be honest, they can be a little bit precious. If the yeast gets stressed they start to produce off flavours, if the yeast gets cold, they end up going to sleep, and if the yeast gets too hot, they die of heat exhaustion.
When our wash/mash has fermented out to about 8% its ready for the magic to happen, also known as the distillation.
STEP TWO: THE STRIPPING RUN.
The stripping run is not as glamorous as the name sounds. Its job is to strip the alcohol out of our mash or wash and take it from about 8% abv to 40% abv. Typically these will be hard and fast runs where the distiller won't make any cuts. What are cuts you ask? Read on below to find out.
STEP THREE: THE SPIRIT RUN
Arguably the most critical run this is where the distiller gets to decide what type of alcohol the spirit becomes. Gin, rum, vodka, whiskey, aren’t they all the same?
Well yes, and no, the spirit run is typically much much slower. We have even had spirit runs take 24 hours (a lot of coffee was consumed this day). During the spirit run the distiller focuses on the proof/abv, he wants the spirit to exit the still while making cuts. Think of cuts like a rattlesnake, the heads are where all the venom and nasty stuff is, no one wants to drink that, so we discard them, the tail's are where the rattle is and ewww who wants to drink that (also they smell like wet cardboard) and what's left, the centre or the hearts this is where the clean and pure ethanol is full of flavour and goodness. Now, why is this critical? Well you know those cheap bottles you find on the bottom shelf? They’re cheap because they are full of heads and tails. No thank you! Now from here, vodka is ready to be bottled, whisky and rum can be put to sleep in casks, but gin still has one final step to go.
SO HOW IS GIN MADE?
There are two main methods that distilleries use to give their Gin its unique taste.
The first is steeping. This is essentially a fancy way of saying soaking them for a period. Most distillers will aim for between 24-48 hours but some may choose to soak there botanicals for hours, minutes or seconds. This is up to the distiller and will have an impact on the overall flavour profile.
Once steeping is completed the spent botanicals may be removed from your resulting mix. This ethanol mix is then transferred into the still and redistilled, resulting in a juniper/botanically charged distillation which is ready to use in the final product.
The second is vapour infusion, a process of taking Juniper and other botanicals and inserting them in the vapour path. When distillation takes place the ethanol vapours rise up and are forced to travel through the botanicals. The resulting spirit produced is infused with the botanical characteristics that we know as gin.
From here our gin is ready to be proofed and bottled for your enjoyment.
