Some popular Glen whiskey brands available in the market include Glenfiddich, Glenlivet, and Glenmorangie.
The basic answer is YES, what ever is your preference. I've seen people mix scotch with just about everything. Myself, I don't drink much scotch, but with a good single malt whiskey (like Glenfiddich) I drink it neat (no ice, no water). If you were to come to my house, and mix my Glenfiddich with anything more then ice, I would hide it the next time you came.
Glenfiddich is a single malt Scotch whisky (spelled without the "e") not a Bourbon. Bourbon whiskey is made from at least 51% corn with other grains, aged in only brand new American oak barrels which have been charred on the inside. No minimum aging period (contrary to popular belief, unless the bottle states "straight whiskey" on the label in which case a minimum of 2 years) Single Malt whisky, such as Glenfiddich is made from 100% malted barley and aged in any oak barrel for a minimum of 3 years (in the case of Glenfiddich a minimum of 12 years as stated on the label.

Im not sure
The Glenfiddich Distillery was founded in 1886 by William Grant in Dufftown, Scotland. The first single malt whiskey ran from the stills on December 25, 1887. It is sold in 180 countries, is the world's best selling single malt, and accounts for approximately 35% of single malt sales.
If it has been kept cool and out of the sun the entire time, assuming it's unopened, it will still be fine, and for many years to come.
Glenfiddich is the name of one of the world's most famous single-malt Scotch whiskeys (or, if you prefer, whiskys).
