Whiskey comes in many forms, but bourbon is America's spirit The origins of bourbon are both known and debated.  We know early settlers in Virginia and Kentucky made use of the abundance of corn to distill their whiskey, but there are a variety of stories on who was first to put it in a new, charred oak barrel and to actually call it bourbon.  No matter the exact origins of bourbon we now have a spirit that is all American to enjoy.  Congress declared so in 1964 stating that bourbon is a "distinctive product of the United States."  Score one for America. We're joined this week by Bruce Tierney, all around aficionado and spirit consultant to .  Tierney shares with us the history of bourbon, let's us know what it takes to call a whiskey bourbon, and offers some suggestions on affordable options to test the waters as well as some of the rarer bourbons to seek out.  We also discuss what flavors to look for when tasting as well as common off flavors, and a quick course on how to taste your bourbon. There's much more information on bourbon than we could cover in this show so we've included additional information and resources here.  Side note, if you're used to sampling beer in 4 oz pours know that 4-5 1 oz pours of bourbon kick harder than you think.  Proceed with caution.

Must be produced in the United States Many people mistakenly believe bourbon must be made in Kentucky but it can be made anywhere in the US.  Several other countries support the American origin, but some do not.  Be careful when purchasing overseas. Must be made from at least 51% corn Has to be aged in new, charred oak barrels Can be distilled to no more than 160 proof.  Higher proof distillation begins to strip flavors. Has to be entered into the barrel for aging at no more than 125 proof Must be bottled at 80 proof or more There is no minimum age requirement for bourbon as long as it meets the above guidelines Outside of these requirements there are several variations allowed such as wheated and "high rye" bourbons, bottled-in-bond, straight bourbon and blended bourbons. How to begin your bourbon experience Tierney has offered up his very detailed advice on how to get started with bourbon including notes for selecting a bourbon, glassware and tasting. My first recommendation for someone new to bourbon is to start your experience by tasting standard bourbons from the major producers first before deciding if you want to branch out and try other brands. I recommend brands that tend to be between 90-100 proof. Yes, that may seem a bit hotter at first but they also tend to be more flavorful. The minimum permitted proof is 80 proof and at that point you are drinking a good bit more water than bourbon anyway! If it seems intimidating to shell out the money to buy a bunch of different bourbons you are right! Although all of the major bourbon producers have a brand that costs in the $20-35 range it can still be a lot of money. Pick a couple that are of interest or are readily available in your area and start with those first. Don't try too many different brands to start with. Or if you are fortunate enough to live near a bar with a good bourbon selection start by tasting different bourbons a glass at a time if you don't want to commit to buying a full bottle. Any bourbon bar worth its name will have many if not all of the standard brands from the major distilleries. If they don't then you are in the wrong place! Try to learn a bit about the different bourbons you have selected. The internet can be your friend here. I can personally recommend as a good source for information about bourbon and many other types of spirits. Remember all bourbon is made from at least 51% corn but what is the rest of recipe of grains, known as the mashbill, that makes up the bourbon? Most bourbon use either rye or...
