    Cleaning is one of the most important steps in brewing. It kills microscopic bacteria, wild yeast, and molds that may cause off-flavors in your beer. Make certain to clean all equipment that comes in contact with your beer by following the directions below:

    1. Fill clean keg with warm water to line mark 1 on the back, then add ½ pack (about 1 tablespoon) of No-Rinse Cleanser and stir until dissolved. Once dissolved, the solution is ready to use. Save the remaining ½ of No-Rinse Cleanser because you will need it for bottling.

    2. Screw on lid and swirl the keg so that the cleaning solution makes contact with the entire interior of the keg, including the underside of the lid. Note that the ventilation notches under the lid may leak solution. Allow to sit for at least 2 minutes and swirl again.

    3. To clean the spigot, open it fully and allow liquid to flow for 5 seconds and then close

    4. Pour the rest of the solution from the keg into a large bowl. Place your spoon/whisk, can opener and measuring cup into the bowl to keep them cleaned throughout the brewing process. Leave them immersed for at least 2 minutes in cleaning solution prior to using.

    5. After all surfaces have been thoroughly cleaned, do not rinse or dry the keg or utensils. Return lid to top of keg, proceed immediately to brewing.


    Brewing beer is the process of combining a starch source (in this case, a malt brewing extract) with yeast. Once combined, the yeast eats the sugars in the malt, producing alcohol and carbon dioxide (CO2). This process is called fermentation.

    1. Remove the yeast packet from under the lid of the can of Brewing Extract,(not needed for this recipe) then place the unopened can and BrewMax LME's in hot tap water.

    2. Place both packets of grain into a muslin sack tying it closed, then trim away excess material.

    3. Add 8 cups of water to 1 gallon or larger pot. While water is still cool, add the booster packet and stir until dissolved. Heat the booster water until it reaches 155-160 degrees. Once the water has achieved this temperature range, add the grain sack so that it is fully submerged and maintain temperature range for 30 minutes. 

    4. After 30 minutes has passed, remove grain sack, and rinse it with 2 cups of hot water using a colander or strainer while allowing the runoff to flow back into your pot. Discard grain sack.

    5. Bring your mixture of grain water and booster to a boil, stirring occasionally to avoid scorching. Once the mixture is boiling, add both LME packets and the 1 ounce of cocoa powder and allow to boil for 5 minutes, while gently stirring. Once 5 minutes is up, remove the pot from the heat. 

    6. Open the can of Brewing Extract and pour the contents into the hot mixture in your pot. Stir until thoroughly mixed. This mixture of unfermented beer is called wort.

    7. Fill your fermenter with cold tap water to the mark 1 on the back. If using any other fermenter this would be approximately 1 gallon of water.

    8. Pour the wort into your fermenter, and then bring the volume of the fermenter to mark 2 by adding more cold water. 

    9. Stir your wort mixture vigorously with your sanitized spoon or whisk.

    10. Sprinkle the S-04 Dry Ale yeast packet into the keg, and screw on the lid. Do not stir.

    Put your fermenter in a location with a consistent temperature between 68° and 78° F (20°-25° C), and out of direct sunlight. Ferment for 14 days.

    STEP 3: Adding Extras

    Adding extras is the process of adding additional ingredients to a beer which will impart more flavor and aroma in your finished brew.

    1.  At 10 of fermentation- Place flaked or shredded unsweetened coconut on a clean baking pan, covered with parchment paper. Spread the coconut evenly over the paper with a sanitized spoon or washed hands, and place in the over at 350 degrees (turning occasionally to promote even browning) until the coconut achieves a golden brown toast. Be mindful not to burn it.
    2. Once the coconut is toasted, remove from oven and allow to cool. Once cool, add coconut to sanitized muslin sack and tie closed so that coconut is not overly compacted. Carefully remove the lid of fermenter and place the coconut inside.
    3. Then add .25 teaspoon of coconut extract and replace the lid.


    After 14 days, taste a small sample to determine if the beer is fully fermented and ready to bottle. If it tastes like flat beer, it is ready. If it’s sweet, then it’s not ready. Let it ferment for 3 more days (17 total). At this point, it is time to bottle. Do not let it sit in the fermenter for longer than 24 days total.

    1. When your beer is ready to bottle, fill a 1-gallon container with warm water, then add the remaining ½ pack of the No-Rinse Cleanser and stir until dissolved. Once dissolved, it is ready to use

    2. Distribute the cleaning solution equally among the bottles. Screw-on caps (or cover with a metal cap if using glass bottles) and shake bottles vigorously. Allow to sit 10 minutes, then shake the bottles again. Remove caps and empty all cleaning solutions into a large bowl. Use this solution to clean any other equipment you may be using for bottling. Do not rinse.

    3. Add 2 Carbonation Drops to each 740-mL bottle. For 1-liter bottles, add 2 ½ drops; for ½-liter bottles add 1 drop. Alternatively, you can add table sugar using this table as a guide. 

    4. Holding the bottle at an angle, fill each bottle to about 2 inches from the bottle’s top.

    5. Place caps on bottles, hand tighten, and gently turn the bottle over to check the bottle’s seal. It is not necessary to shake them.

    6. Store the bottles upright and out of direct sunlight in a location with a consistent temperature between 70°-76°F or 21°-24°C. Allow sitting for a minimum of 14 days. If the temperature is cooler than suggested it may take an additional week to reach full carbonation. 


    After the primary carbonation has taken place your beer is ready to drink. We recommend putting 1 bottle in the refrigerator at first for 48 hrs. After 48hrs. give it a try and if it is up to your liking put the rest of your beer in the fridge. If it does not taste quite right, leave the bottles out at room temp for another week or so. Keep following this method until your brew tastes just how you like it. 

    This process is called conditioning and during this time the yeast left in your beer can help clean up any off-flavors. Almost everything gets a little better with time and so will your beer

    Rated 5 out of 5 by joegonzo999 from Best Coconut beer I've ever had! I am a big fan of coconut. Ever since Ashley Collins told me that this one was coming, I've been salivating over it. Well talk about being worth the wait! Ashley hit a home run with the Coconut Island Porter recipe! What a smooth beer with just the right amount of coconut flavor! To be fair, after checking with her to make sure it wouldn't ruin the recipe, I doubled the coconut extract to make sure I had that flavor. Ultimate perfection! Even one friend of mine who is not a fan of coconut loved this beer!

    Rated 5 out of 5 by Glonker from Move over Maui Brewing coconut porter This beer turned out great. I doubled the coconut extract and can say that I would advise just sticking with the original ingredients instructions. I love coconut but the extra dose I gave it makes it very prominent; so depending on how much you enjoy that flavor will determine what to do. This batch smelled amazing while making it in the kitchen.

    Rated 5 out of 5 by Stopthemad from So delicious, my new favorite beer This is a light bodied but FULL flavor beer. This is almost like a milkshake in a glass with the cocoa and coconut flavors, but no sugary sweetness. I have made the Nilla Porter and was not a fan, but this recipe has turned me into a convert for MrBeer Porter! And this is even before it has fully carbonated.

    Rated 4 out of 5 by Jim71 from Very nice porter While this is a good tasting porter, the cocoa flavor was bold but coconut flavor seemed to me to be lacking a bit. When making this again I would add more coconut extract but that just my preference... I love coconut.

    Rated 5 out of 5 by Tom05 from WOW! This is perhaps the best beer I have made. Although I used vanilla vs coconut extract (did not have any coconut extract at the time) this was really really great beer. I highly recommend.
