Questions
Hi Odin,
I was also wondering if I could ask you a bit about gin louching. I usually ask people on the distilling subreddit when I have questions about distilling and you'll be pleased to know that you are very popular on reddit, and are often mentioned by other distillers on there. One person said I should ask you directly.
I have had some issues with the gin louching when I add water to it. We usually distill 18L of botanical distillate at 78% abv and then add NGS at 96%abv and de-ionized water to bring the volume up to 200 liters and 40% abv. I have the following questions:
1) Does it matter how quickly I add in the water to the alcohol? Someone told me to add in the water slowly to avoid louching.
2) I've read that making a heads cut during spirit collection helps to prevent louching. I started taking 100mL off, and I do notice there are a lot of oils in it. Why is that? I thought the heavier oils would be in the tails, so why are there so many oils at the beginning of spirit collection?
3) I know that making a heads cut during spirit collection, making sure the spirit and water are around the same temp when mixing, and adding more neutral grain spirit to the final product help prevent and get rid of louching. Are there any other ways to get rid of louching?
Any advice would be appreciated. Thank you.
