Martin Miller was a great gin innovator and an early proponent of the modern craft gin movement. The gin is boldly citric, and makes a great G&T.
Miller's is made in England in a two stage process where the citrus elements are distilled separately from the spices. This process keeps the citrus quality fresh and to the fore.
The spirit is then shipped to Iceland to be cut with pure glacier melt water. Yes, it sounds bonkers but this has been one of our favorite gins since forever.
