    STEP 1: Sanitizing

    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, then remove the label from the can. Place the unopened can in hot tap water

    2. Using the clean measuring cup, pour 4 cups of water into your 4-quart or larger pot. Add your booster packs slowly while stirring the cool water until dissolved. Bring water to a boil, and then remove pot from heat.

    3. Open the can of brewing extract from the bottom of the can and pour it into the pot. Stir until thoroughly mixed. This mixture is the wort.

    4. Fill the keg with cold water to line mark 1 on the back. The water must be cold (ideally from the refrigerator) with a temperature of 40-55°F/4-12°C. For the best results, we recommend using bottled spring water or filtered tap water. If using any other fermenter this would be approximately 1 gallon of water.

    5. Pour the wort into the keg and then bring the volume of the keg up to line mark 2 by adding more cold water. Mix vigorously with the plastic spoon/ whisk. Be careful to not scratch the inside of the keg, which could create small spaces for bacteria to grow. (If you have a different fermenter top it off with cold water to the 8.5-liter mark).

    6. Sprinkle the entire yeast packet into the keg and then screw on the lid.Do not stir.

    7. Allow your fermenter to sit for 10-14 days.

    Store the fermenter in a cool, dark place between 68-78°F/20-26°C for the yeast to work properly. The ideal temperature range is 70-72°F / 21-22°C. After a few days the foam and activity will subside and your batch will appear to be dormant. However, the yeast is still at work, slowly finishing the fermentation process.

    STEP 3: Bottling & Carbonating

    After 10 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 4 more days (14 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 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 solution 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 to sit for a minimum of 14 days. If the temperature is cooler than suggested it may take an additional week to reach full carbonation. 

    Tip from our Brewmasters

    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 4 out of 5 by Keljr0207 from Nice brew I wanted to try making a dark beer other than a stout. A local craft brewing company makes a Maple Porter that is so popular that when it is released it sells out within hours. I made my own using 1 cup of dark amber syrup which is added one week into the fermenting process. The maple flavor in the beer itself is very subtle, the aroma that comes from opening the bottle is intoxicating. If making a Maple Porter, I would recommend either a Grade B syrup which is darker than the dark amber I used or a Maple Extract.

    Rated 4 out of 5 by jimed77 from Elk camp favorite! With an elk camp coming in the cold north country, I brewed up a batch of this excellent porter to enjoy around the campfire. It poured fantastically with a thick, rich foamy head. We (my hunting buddies and myself) found it to be wonderfully full-bodied with fantastic coffee and chocolate tones a nice tart finish. Hard to believe something served ice cold can make you feel so warm inside! Will definitely make again (and again and again)!

    Rated 5 out of 5 by Bohemian Master Brewer from As Good As Any Micro Brew Porter Last year I brewed a porter from an extract kit from a local brew store. It turned out just so so. This Spring I decided to try a Mr. Beer Porter and it totally blew me away. Full flavors with overtones of chocolate and coffee with a nice thick head. It tastes every bit as good as any micro brewed porter I've ever had and blew the extract kit porter into the weeds. I used the Robust LME and found that it hit its stride after 8 weeks of conditioning. If you like dark beers, you'll love this porter.

    Rated 5 out of 5 by The Bagpipe Brewer from Outstanding taste prior to bottling added Coffee Hey Guys, Bought this a month and a half ago. Just bottled it the other day. When I made it I subbed one liter of coffee in for water to bring it up to the full 2 gallons and trust me the flavour is awesome. It hasn't fully conditioned yet, but I tasted it before bottling and the aroma and colour were great. The rich flavour and had strong coffee notes, which is what I was going for.

    Rated 5 out of 5 by Ed H from Staggerback Stout I ordered the American Porter to brew another Staggerback Stout. The first time I brewed this batch, I had (and still have) a huge about of foam that oozes from the bottle. I think I may have had an infection in the first batch, so it's time to try again until I get it right. Even with a presumed infection, this is one great beer. I'm sure I will order this again. I want to brew this straight up with maybe a little coffee to create a Java Porter...

    Rated 5 out of 5 by rsnake2 from Great beer This American Porter is the first beer that I brewed. I am very impressed. First that the brew kit (LBK) worked and second that it produced a very good beer. As a newbie I will stick to the extract refills and have already purchased three more. Good job Mr. Beer !

    Rated 4 out of 5 by BrewCat from First Home Brew This was my first home brew, and it was pretty easy to follow the directions. I did everything faithfully, except (my fault) I forgot to tilt the first bottle when filling it for the conditioning phase. Needless to say, it got oxygenated and tasted funky - so be careful not to do that ! After the recommended conditioning time and chilling 2 days in the fridge, the second and third bottles still had a slightly sour "off" taste but after waiting another week, the 4th bottle tasted fine. My advice would be to let it age at least another week or two before drinking. Cheers !

    What's the difference between a standard kit and a deluxe kit?

    Asked by: Nate401
    Our Standard refills come with Brew Max Booster, a corn-based booster that increases alcohol and body but doesn't add any color or flavor. The Deluxe refills come with LME (liquid malt extract) packs, the same kind of malt that comes in the can without any added hops. This adds alcohol and body like the corn-based Boosters but also adds more color and flavor. I usually suggest that if you have a favorite refill, try it both ways to see which becomes your absolute favorite. I also usually suggest Deluxe options for the more malty styles like Oktoberfest or porters/stouts since you typically want more malt character in those styles but to each their own. Cheers.

    Can you tell me what type of appetizer or food pares best with this beer. Brewing it right now for a friends beerfest and we need to pare with food. Thank you
