Unfiltered – a monthly column by coffee expert Sam Mylrea of CoffeeKind.com on what’s brewing in that world.

The coffee grinder is arguably the most important component of your home barista arsenal.  Ask any coffee professional on how to improve your coffee game and they’ll talk to you about grinders. But where to start? There’s a never-ending supply of information out there. We’re here to arm you with the most important tips so you can find the grinder best suited for your needs.

Having a decent grinder is one of the easiest ways to control your coffee’s taste quality. Stores offer two kinds: blade and burr. The blade coffee grinders are often cheaper in price than burr grinders, but you sacrifice in even ground production. A blade grinder is reminiscent of someone taking a machete to a piece of raw meat and blindly chopping it to various sizes. Just like how those randomly sized pieces wouldn’t grill evenly and at the same rate, the coffee grounds won’t extract evenly.

Here are some key questions to ask yourself when considering a coffee grinder purchase:

1) How often do I drink coffee?

If you drink coffee every day, then a grinder purchase would be in your favor. If you drink coffee once a month, this might not be worth the investment.

2) How fresh are the beans that I’m buying?

One of the most compelling reasons to buy a grinder is so you can grind fresh. If you buy coffee that has been sitting on the supermarket shelves for three months, chances are that a grinder won’t significantly affect the taste quality of your coffee. If freshness is important to you (and here at Coffee Kind, we do believe that fresh coffee has a distinctly different taste than 3-month old coffee), then the coffee grinder will only enhance the resulting cup’s taste quality.

3) How much am I willing to spend?

As we mentioned earlier, blade grinders are considerably cheaper. However, if you’re willing to do some manual labor, some hand grinders like the Hario Mini Mill come in as low as $33. The cheaper manual burr grinders use ceramic burrs, which can wear down more easily than steel burrs. But if you’re just trying out a burr grinder, ceramic burrs will work out just fine for you.

4) What method am I using to make coffee at home?

Your coffee grinder should be tailored to your needs. For the majority of home baristas, you’ll need a grinder that can produce coarse and medium grinds equally well. If you are lucky enough to own an espresso machine, a grinder built for espresso is worth looking into. One of our favorite manufacturers for automatic grinders is Baratza– they provide a wide-range of quality grinders with excellent prices & customer support.

Once you’ve purchased a coffee grinder, here are some quick tips on maintenance and overall coffee taste:

-Clean regularly. If you make a daily cup, clean at least once a month.

-Use grinder-friendly cleaning products. If you have ceramic burrs, gentle soap and air drying will work. If you have steel burrs, purchase a grinder-cleaning product, like Urnex’s Full Circle Cleaning Tablets, that will soak up the coffee oils.

-Use the correct grind for your coffee brewer. Too coarse of a grind in espresso will result in a watery cup while too fine of grinds may back-clog your machine. Our handy grind chart will help you with the correct grind size for your brewer.

How to start your own home bar: the essential spirits
Home Bar

When you start getting into cocktails, drinking them is only half the fun -- making them is part of the appeal too. If you start making your own drinks at home, you'll soon find that you can often create better or more interesting drinks than what you're served in most bars. And even better, making drinks for other people is a great way to try out new combinations, learn about spirits, and make your friends and family happy too.

However, moving beyond the simple spirit plus mixer style of drinks which most people make at home and into the world of cocktails means that you'll need a wider array of spirits on hand than you might be used to. It can take some time and research to build up a well stocked bar, and choosing high quality spirits isn't a cheap endeavor. It's worth it, though, for the pleasure of being able to try out classic cocktail recipes and experiment with making up your own creations too.

You’re overlooking the most important ingredient in your cocktail
Steel Hibiscus cocktail.

When you list off the most important parts of making a good cocktail your mind likely goes immediately to good ingredients: quality spirits, freshly squeezed citrus juices, and well-matched mixers. You might also consider the importance of using the right tools, like getting a proper mixing glass so your stirred drinks can be properly incorporated, or a good strainer so that there aren't little shards of ice in your cocktails. And then there are the fun additions like elaborate garnishes, bitters, or home-made syrups which can add a personal touch to your drinks.
All of those things are important, absolutely. However I think there's one ingredient that can make or break a good cocktail, and it's something many drinkers don't ever stop to consider. It's the humble but vital ingredient of ice.

Why ice is so important
In mixed drinks like a gin and tonic or a screwdriver, ice is added to the drink primarily to chill it down to a pleasing temperature. That's a topic we'll come back to. But in cocktails which are shaken or stirred, ice is far more important than that. Cocktails are typically composed of between around 20 to 30 percent water, and this water comes from the ice used in the preparation process.
When you stir ingredients in a mixing glass or shake them in a shaker with ice, you are chipping away small pieces of the ice so that it dissolves and blends with your other ingredients. You might imagine that water doesn't make much of a difference to taste, being tasteless itself. But it's vital in opening up the flavors of other ingredients. That's why many whiskey drinkers like to add a dash of water to their whiskey when they drink it neat.
If you're ever in doubt of how important water is to cocktails, it's worth trying to make a drink with no ice. Even if you mix up the ideal ratios for a drink that you love and put it into the freezer so that it gets to the chilled temperature that you usually enjoy it at, if you sip it you'll find that your drink tastes harsh, unbalanced, and incomplete. Even for special room temperature cocktails like those designed to be drunk from a flask, you'll generally find water being added at a rate of around 30%.
When you make your cocktails you should be sure to stir for a long time – around 30 seconds is a good start – or to shake for a good while too – I typically do around 12 to 15 seconds – in order to melt enough ice to get plenty of water into your cocktail. Despite what you might imagine, this won't make the cocktail taste watery but will rather make the flavors stand out more as well as often improving the mouthfeel of the drink. A good rule of thumb is to mix or shake until the vessel is cold to the touch. That means your ingredients are sufficiently incorporated with the ice.
