To Louch or not to Louch, that’s the question!
Onwards with louched gins! I visited a distillery once that had a wide array of products. Most of them bottled at 40%. Only their gin was bottled at higher strength. I asked the master distiller why? He said – and taking a look I could see it – that even at the higher ABV of 45%, his gin was on the verge of becoming cloudy (or “louchy” as the word seems to be). Would he go any lower in ABV, the gin would turn almost white.
I asked him what he thought the solution was. He told me that he had talked to two gin experts. One advised him to cut his herbs bill in half. Use like only 50% of the total herbs bill he had used before. The second one told him to buy a chill filter and filter the haze out.
The second solution I really don’t like, because it takes away essential oils AKA taste. And anyone who tells you that chill filtering doesn’t … well, let them chill filter their whiskey for 10 times only to find out it starts to taste pretty much like a vodka! The first solution of using less herbs, isn’t good either. It relies on the assumption that a louched gin is bad. I feel it isn’t. A louched gin is a great indication you got over huge amounts of tasty oils. And that was the goal right? To create a big tasting gin.
So how do we solve the louch? Easy, dilute some neutral / gns to the same percentage as the louched gin, and add a portion. There will be a moment (75:25, 66:34, 50:50, etc.) when all of a sudden the louch lifts. In a second, maybe two. You now have the gin with the most taste possible. And if you think it is too big in taste? Dilute it.
Bottom line? A louched gin gives you a balpark. A starting point that makes it easy to create great tasting gin with the same flavor profile over and over again. And you can always dilute a big taste gin to a lighter one, but not the other way around.
