I have been trying to enjoy my recent purchase of Glenfarclas 105. Suggestions that I've read here at Whisky Forum and elsewhere include opening the bottle and then letting it sit for a few weeks, allowing air to enter. Another online aficionado recommended a decanting procedure by pouring the 105 from the original bottle into a decanter and then back to the original bottle, again letting the contents "rest" for a few weeks.
To me, however, the larger issue of enjoyment involves just how much water to infuse into the dram. Taking the Glenfarclas 105 straight toasts the olfactory and gustatory senses. So far, in a standard SM sniffing glass one-fourth full of the Glenfarclas, I've tried five drops of spring water and had decent but not overwhelming success. Of course, "taste" is very subjective, but I'm interested in hearing from others who have discovered an acceptable whisky to water ratio.
