Whisky manufacturing isn’t the identical as making an inexpensive turbo cider or ale from a package at house (full disclosure, I’ve used these kits earlier than and produced some great-tasting ales within the course of). No, whisky manufacturing is one thing far more.
I like to think about whisky manufacturing as a hybrid between artwork and science. There’s a lot to contemplate and if only one component is barely off, what ought to be an incredible tasting dram will as a substitute prove as mediocre at finest. On this biz, mediocrity simply gained’t lower it.
For those who’re a daily reader of the Nice Drams blogs, you’ll in all probability have learn a few the items I’ve achieved up to now on the significance of cask choice in whisky. Once more, I can’t emphasis simply how necessary the cask is in whisky maturation. One of many major causes for this, is as a result of tannins they convey.
In whisky manufacturing, tannins play a necessary position within the completed product, but I really feel we don’t communicate sufficient about them. That’s about to vary.
As you’ve in all probability labored out by now, immediately’s weblog is all about tannins in whisky and what they do.
What are Tannins?
Brace yourselves as a result of we’re going to get a little bit scientific right here, so that you would possibly wish to seize your lab coats.
With out getting too complicated, tannins are naturally occurring compounds which bind to a variety of proteins and natural compounds and alter their chemical construction. They’re really a type of polyphenol, which is a plant-based compound. As you would possibly count on then, they’re present in quite a lot of plant-based sources, together with fruits, leaves, and wooden.
Tannins are very helpful little compounds, they usually actually earn their preserve. Not solely can they be used within the manufacturing of leather-based, in addition they play essential roles within the booze enterprise, significantly whisky and wine.
How Do Tannins Work?
Now, in nature, tannins are particularly fascinating. They’re present in quite a lot of seeds and un-ripened fruits, together with grapes. Their major position isn’t to make these meals ripen faster, or style nicer. Fairly the other in reality. The tannins are as a substitute there to make the meals style bitter and astringent so animals don’t eat them.
If tannins are designed to make issues style unhealthy, you’re in all probability questioning why whisky and wine connoisseurs communicate so fondly of tannins? Properly, it seems that as they ripen, the construction of the tannins modifications. That is by a course of often called polymerisation. This causes them to work together with different compounds such an anthocyanins, and pectin, and successfully change their style and look.
In whisky and wine manufacturing, tannins play an necessary position, not solely when it comes to mouthfeel, but in addition when it comes to style, aroma, end, and look. Yep, mainly each component of those drinks we love a lot is influenced massively by tannins.
Tannins in Whisky
In wine manufacturing, nearly all of tannins discovered within the wine come from the grapes used to make the wine. Whisky nonetheless, will not be produced from grapes, so the place do the tannins come into play? Properly, they arrive from wooden as a substitute.
In addition to occurring naturally in issues like grapes, you might keep in mind how I discussed tannins are additionally present in seeds. Now, acorns are seeds, and from these seeds, mighty oak bushes develop. This identical oak wooden is used to supply the overwhelming majority of whisky casks and barrels. Now you’ll be able to see the place the tannins in whisky come from.
Probably the greatest issues about whisky is the truth that every dram tastes so totally different. Whereas some from be candy and peppery, others may be woody and creamy. Whereas there are many the explanation why every whisky tastes totally different to the final, tannins actually play an element.
The older the whisky, the extra time it’ll have spent within the cask and the extra time the tannins could have needed to work their magic. Totally different species of oak additionally comprise totally different quantities of tannins. Bourbon casks for instance, usually comprise fewer tannins than European oak sherry casks.
How do Tannins Affect Whisky?
So, we’ve established that tannins can successfully rework a whisky, and form it into an distinctive dram, however how precisely do these compounds affect these drams?
Listed here are just some of essentially the most outstanding methods by which tannins can have an effect on a whisky.
Mouthfeel
Tannins are mostly related to mouthfeel, not solely in whisky, however in alcoholic drinks manufacturing on the whole.
Mouthfeel is necessary as a result of it helps change how the whisky feels in your mouth. it makes it so that you don’t really feel you’re ingesting whisky flavoured water. Within the mouth, the tannins bind with proteins in our personal saliva. This creates a mouth-coating sensation that always makes the whisky really feel a little bit thicker and dryer.
Look
The tannins discovered within the oak used to make whisky casks may assist give the whisky its unbelievable color.
When the spirit first enters the cask, it’s basically clear and appears similar to water. It takes on its color from the tannins as they leach from the wooden and into the liquid. That is sometimes why older whiskies matured for longer are usually a darker hazelnut brown color, relatively than a pale straw or amber.
After all, there are different components that have an effect on a whisky’s color, together with how the cask has been handled and what it saved beforehand. Closely charred barrels, and casks which beforehand saved darkish liquids akin to crimson wine or port, may give the whisky a deeper extra intense color.
Flavour
And eventually, we have now flavour.
In nature, tannins are designed to make meals style bitter, astringent, and mainly inedible. Certainly you wouldn’t wish to put one thing designed to make issues style inedible right into a product designed to be consumed? Properly, don’t fear, as a result of in small quantities, and when used accurately, tannins can rework a nice-tasting whisky into an impressive one.
Tannins add a slight bitterness to whisky, in addition to an astringency which supplies it a dryer sensation within the mouth. This works very properly and helps steadiness the flavours and notes of whisky completely. Consider candy and bitter and also you’re heading in the right direction.
