Do you like flavored spirits? Are you the sort of person who likes to make their own things from scratch (If you're reading this, you might be!)? Do you want coconut rum, but are pretty sure you won't want it for about ten days, give or take? Then this Instructable is for you! We'll walk you through the vaguely frustrating but rewarding process of making your own coconut rum.

Theory:
The idea behind all flavored spirits is infusing. You take something tasty, make a sugar syrup flavored with it, let it steep in something alcoholic (but relatively tasteless) for a while, and when you're done you've got a flavored alcohol. We're doing coconut today, but this procedure can be applied to pretty much anything you'll want to make.

It's really quite simple, sort of fun, and impresses the heck out of people!

So let's gather our mise and get started!

Mise en Place for Coconut Rum:
Software:
1 ea Coconut
1 750 mL bottle of decent but not amazing white rum
1.5 cups water
12 oz. by weight white sugar

Hardware:
1 screwdriver
1 Vegetable peeler
1 Hammer (May or may not need)
1 Drill and drill bit (May or may not need)
1 Colander or large strainer to wash the peeled coconut meat
1 medium pot
1 Rubber spatula for stirring
1 food processor with shredder disc (or box grater)
2 1L glass jars or one 2L glass jar. Wide mouth will really help. Mason jars work great

(Hardware needed at the end for finishing)
1 Strainer
1 Coffee Filter
1 Large mixing bowl to strain into (Might not need depending on how you decide to strain)
1 Funnel
1 Nice container for your finished product, 750-1000 mL

Initial steps:
1. Preheat oven to 375 degrees F
2. Combine sugar and water in the saucepan on the stove, but don't turn on yet

Step 1: Cracking the Coconut

The first thing you need to do is open up the coconut. Some coconuts out there (like mine) are 'easy open', meaning they have been scored around in a circle with a saw to help get them open.

1. Get your drill (CLEAN the bit!) and drill through two of the eyes and drain the coconut water into a container. I know what you're thinking: It's so SO tempting to save the water and put it into the rum. It doesn't work! It's not going to blend it and you'll wind up with a fatty layer on the top of your rum. It's possible you might be able to use it as part of the liquid in the sugar syrup and it'll mix that way, but I haven't tried that yet.

2. Put the coconut in the oven for about 15 minutes. This will dry the shell out and make it easier to pull away from the skin and the meat.

3. Remove from oven and let sit for a minute or two (it'll be HOT) and remove the hard outer shell with whatever tools you require: mostly a whack or two with a hammer and pry with the screwdriver.

Step 2: Peeling

Once you have the shell off, you need to peel the skin. Break the coconut into manageable chunks (if the shelling process didn't), and peel the skin off with a vegetable peeler. As you clean each chunk, put it into a strainer in the sink.

When everything is peeled, give the chunks a good rinse to get any stray particles off.

Step 3: Shredding

Shred the coconut. A food processor with shredder disc makes this simple and fast, but if you don't have one, use a box grater and the largest holes.

Step 4: Making the coconut syrup

Now you're going to make the sugar syrup. If you really don't want to add sugar to the recipe, you don't have to (but you'll be missing out on some flavor, it won't be particularly sweet, and it might take a little longer), simply divide the coconut into the two jars (might even fit into one) and pour on the rum.

Sugar syrup, I've found though, is the way to go with these for 'sweet' infused spirits (fruit spirits, not so much pepper or chile vodka).

1. Combine the sugar and water in the medium saucepot if you haven't already
2. Put on stove over medium high heat. You're going to want to stay put and watch, as it'll go fast. You want to completely dissolve the sugar into the water, then simmer away some of the water. It will get cloudy then go clear.
3. Let simmer about two minutes. You do NOT want it to start turning brown (making sugar syrup, not caramel) a little color won't hurt it, but that's not what we're going for.
4. Add the coconut and stir to combine. It's going to look pretty 'dry' since there's more coconut than syrup, but it will cook down a little. I had a particularly high yielding coconut so it almost didn't look like enough, but your mileage may vary.
5. Let simmer another couple minutes then remove from heat.
6. Let cool a bit before proceeding...sugar is VERY hot.

Step 5: Dividing into jars

Carefully divide the sugar and coconut mixture into the two 1 liter jars (or your one big jar). You want approximately the same amount of both syrup and coconut in each jar, but you're going to combine them in finishing so it's really not that critical.

Add the rum, again as near to even in both jars as you can. Use the spatula to push any coconut around the inside of the jar into the rum.

Step 6: Infusing and Finishing

Close your jars and put them somewhere they won't be in the way. I'm using the 'mason jar, squeeze bottle, spare silverware, and Cognac' cabinet found in most households, but anywhere clean and out of the way (cool, dry, out of the light) will do.

This is where the waiting starts. Let it sit, giving a light shake every other day, for one week. At the end of a week, give it a taste to see how it's going. Odds are it won't be ready, but you'll get an idea. The main thing you're looking for right now is sweetness. The coconut flavor will continue to develop (and I guess you can add more coconut at this point, and it's alright if you want to use a little bagged and not bust out a whole new coconut), but it's as sweet as it's going to get. If it's not sweet enough, make a note to make a little more sugar syrup when you go to bottle to adjust the sweetness with.

At the end of the second week, give it another taste and decide if you want to bottle it or wait a bit more. At this point, you won't get that much more flavor out of it by letting it sit more, but do so if it needs.

To finish the rum, put a coffee filter inside your strainer and place over a mixing bowl, and pour the rum through. Note it's never going to be perfectly crystal clear, since we're not filtering it as much as a commercial operation does.

Cautionary Note: The leftover coconut or fruit isn't nearly as delicious as it seems like it'll be. Remember: All the flavor went into the alcohol. Cherries from a batch of cherry bourbon tasted like cardboard soaked in kerosene.

Funnel into your bottle, and you're done! Congratulations, you've made your own coconut rum! Now that you have the basic technique, you can make all sorts of good stuff! Cranberry vodka for the holidays, chile or black pepper vodka for cocktails (no sugar syrup step for 'savory' infusions), delicious cherry whiskey.

Hi Rum lovers,

We have made extensive testing and trials and best way to spice up a neutral good Rum is to use some Cinnamon extract (have some quality sweet Cinnamon sticks soak in high degree alcohol for several months) + some Vanilla extract. If you add a tiny hint of Molasses (only a pinch) or good Honey, that will do wonders - but beware - both can create bottom sidiments so be carefull how you do, or make a decantation after one week to be on the safe side.

I you mature with some toasted oak - better

Good luck !!

I love my Capt. Morgans Spiced Rum. My favorite Trader Joes has a good rum (not spiced) for $10.00 less. What is a good way to spice up my TJ's rum? Thanks

To speed up the process place the jars in the freezer at night while you sleep and take them out in the morning. Old moonshiner's trick.

2 years ago I infused a bottle of Vodka with cherries freshly plucked from the tree in our colony. Forgot about it but found it last week when cleaning up. It was standing way inside the cupboard, almost impossible to spot. Thinking that it must've been spoilt after this long time I took a sip and it's AWESOME! So I find this instructable very interesting and inspirating. Infusing your own drinks gives flavors that can't be store bought.

Hi, thanks for reading! There's definitely no reason you can't let these go a good long time, but I think you'll run into a point where you've gotten everything out of the fruit you're going to. I'd have to look into it, but I imagine you don't even HAVE to decant off of the flavoring ingredients if you don't want to for whatever reason (I dunno, it'd look neat to have a whole row of infused spirit bottles you did yourself!). If you're going to do that, I'd recommend giving the bottles a shake every now and then to move things around: the fruit at the top, partially exposed to air, might begin to mold and rot. This might be an even bigger problem as you pour off the liquor as you drink it. Eventually the fruit will become 'beached' and at that point you should decant. I've got a recipe somewhere for an orange brandy that I think said to stash it under the sink for at least three months! Oddly enough, I think that was when I realized "Hey wow, you can do this stuff??"
