Two questions bud:
What makes a wheated beer or whisky taste so much smoother to me? I like Ryes too, but wheated is always my preferred.
Beers different, and alot of different factors go into it. But beer can be made from almost anything, but rice and wheat tend to be smoother then the uncommon rye beers, and the more common barley.
So American whisky has a mash bill consisting of these ingredients in different amounts. Corn, wheat, rye/ malted rye, barley/malted barley . You can look at these at an high level and see that a rye has to have at least 51% rye, Bourbon has to be at least 51% corn etc.. Basically these grains are heated and crushed/mashed (hence the name) and then fermented into a beer then distilled. This is now unaged whisky, that goes by other names... Moonshine, white dog etc. Then it is put into barrels and aged gettings its color.
So lets look at Bulleit rye (95% rye, 5% corn) vs Bulleit Bourbon (63% corn, 27% rye, 10% barley) Same distillery but different flavors from the base mash bill.
The base for all Van Winkle and Weller stuff at 70% corn, 15%wheat, 14% barley... hence it is considered a wheated bourbon. More expensive ingredients and smoother, sweeter taste. (Side note I own 5 bottles of the last real Stitzel Weller juice, Pappy is no longer from that source and neither is the stuff labeled Weller.)
These taste much different from each other as the base mash is made from different ingredients that stick through the distillation process.
Corn is the cheapest ingredient and used the most... it imparts a sweetness that in Corn whisky (90% corn or higher) is very noticeable and reminiscent of sweet corn. So Rye is spicier, barley is barley and more neutral, wheat is sweet and smooth. That make sense?
When you are doing professional taste tests (not sure what it’s called you do), what do you use to cleanse your pallet with? I’m more interested in something with whiskey, scotch, etc. that won’t influence the next poor.
Well if I am designing a tasting, I go from mild to more extreme in order so they do not step on each other. You might be surprised how "thin" many whiskies are after you drink a very flavor packed one, something you thought was strong may taste like water, even though it didn't taste weak when you started with it... Glenfiddich and Laiphroig are actually very "thin" and cannot stand up to stronger whiskies if drank 2nd.
As for what foods... it kind of depends... Generally I like a fresh Italian or French loaf cut into squares, not a baguette, as they can be a little skewed. Marconi Almonds work, peanuts (lightly salted) work. But I also use a nice crunchy (high salt content) hard cheese like a good Parmesan or Swiss with sweeter spirits, and dark chocolate pairs well with smokey stuff, but can skew the palette a little.
I provide the above, but mostly just chase with water and wait a few minutes between samples and make sure I am going from lighter to more extreme in order.
