Rated 4 out of 5 by KGO1 from Good activity for my 13 year old son 3 years ago my family bought me a Mr. Beer LBK kit for Christmas. This started my continuous home brewing activity since. My son always showed an interest but really couldn't participate in the final product. So, last year we bought him a Mr. Rootbeer kit to see if he would take interest. He has and as it turns out, he now makes it routinely for himself and for family holiday gatherings. His root beer is a big hit, especially with my mother who made root beer back when I was a kid. My son now has 16 bottles and I don't know how many refill kits and keeps a steady supply on hand. We bought him 2 more full kits for Christmas at his request to bump up his ability to maintain a supply of his root beer. Good activity for a kid.

Rated 4 out of 5 by Vernon from Excellent starter kit, fun for kids, tastes great. My kids wanted to help me with brewing my beer, I ended up getting this kit for them to try. Very simple directions to follow, similar to brewing beer but in a fraction of the time, taste better than the big name brand root beers. My kids couldn't get enough of it & a root beer float made from this product is out of this world. Fun for the whole family. Highly recommended product!

Rated 5 out of 5 by Shane from Great for fathers and kids! I bought this to try with my kids since I use my Mr. Beer kit at home quite often. I bought it as a way to have some father/son/daughter time and have them participate in one of my favorite hobbies; making beer. This Root Beer kit is very similar to the LBK kit, a lot of the steps are the same. The whole family actually ended up participating making the Root Beer. It took about an hour top to bottom. I was familiar with how to check carbonation in the bottles by feel, so they went in and out of the fridge at different times. The first bottle we drank was EXCELLENT!!! The kids of course loved it, and I did as well! It really IS good. The kids ended up making root beer floats the next night. All in all, a great way for fathers/mothers to spend some quality time with their kids!

Rated 4 out of 5 by 71Monte from Worth It The kit makes a full flavor old fashioned style root beer. The process is relatively simple and doesn’t require a lot of time. The natural carbonation creates just the right amount of carbonation unlike the over carbonated store bought stuff. My only complaint was to me it was too sweet. Sodas today are over sweetened like the rest of our food. Original sodas were not real sweet. I contacted support and found out I could reduce the sugar by 1/4 cup. This helped but I had to let the root beer carbonate a little longer. Mine is usually done by the second day. All in all it’s a fun project and cool that you’re drinking something you made yourself.

Rated 5 out of 5 by shopperfect2 from The Best Root Beer Ever! I purchased this item about 3 weeks ago. I was a little intimidated at first; but I found the directions were relatively easy to follow. I put the four bottles of root beer in a dark place for 2 days. I put them in my refrigerator for 24 hours. I poured my first glass over ice. The fantastic foam on top was perfect. When I took my first drink, I was hooked. The flavor and carbonation was excellent. It was the best root beer that I have ever drunk. There is no way that I could ever drink a store bought root beer ever again! Please tell me where I can purchase extra bottles. I want to serve this fabulous root beer at our family reunion coming up in mid August. With 2 kits I could make 16 bottles if only I could purchase extra bottles.

Rated 3 out of 5 by epollnac from Taste is off? First timer, followed the directions to the letter, but it tastes 'yeasty', is that normal? Did I do something wrong? Making it with my son was fun... he loves root beer, but wasn't fond of this.

Rated 5 out of 5 by HDWolf from Fun Project Made a batch right after I received the kit. Put one bottle in the frig on day 3 and the others on day 4. Both were good, just the carbonation I like. Will be making this again soon.

We don’t seem to have the yeast in our box. Is there a replacement for this?

Asked by: VPPS
We like to hide the yeast under the plastic lid of the can. It helps keep it secure during shipping. If there isn't a yeast under the lid, please call or email customer service and we'll send one right out for you.

My yeast packet expired. May i use 1/2 tsp of active yeast for breadmaking as a replacement?

Asked by: lsloan
You can use it, but the results may vary. Bread yeasts are less concerned with flavors and more concerned with making carbon dioxide, which might work great with a soda kit. However, you'll want to keep a closer eye on them since they may over-produce compared to the yeast we provide. Cheers.

do you stir in yeast after sprinkling it in?

Asked by: BeckyC
No, do not stir the yeast. You want to stir BEFORE adding your yeast. Cheers!

If I wanted to Keg this rootbeer in a 3 gallon home brew Keg. Would the recipe need to change? I have C02, so wouldn't need the rootbeer to self-carbonate.

Asked by: K23456
You could add slightly less sugar. If you would like, cut the sugar by 1/4 to 1/2 cup. Cheers!

I wanted to transfer the root beer from the plastic bottles after its finished chilling from the refrigerator to glass bottles with caps. Do you see any issues with that? I plan on keeping enough space in the bottle. Thoughts? Thank you.

Asked by: Chaps
That should be okay as long as the bottles stay refrigerated the entire time until they are consumed. You may need to vent the bottles if you keep them for over a week. Cheers!

I was given a root beer kit as a gift about five or six years ago and never used it I just found it is it still good

Asked by: Bobpat
The only part of the kit you will need to worry about is the packet of yeast. If you have exceeded the expiration date on the yeast packet, that will need to be replaced. Cheers!
