I was skeptical, but when used with distilled or reverse osmosis water as recommended, it has reliably improved my mash efficiency. However, it's overpriced. $2.50 would be a more reasonable price point since there's probably less than 25 cents worth of raw materials in there, and would likely result in more people using it regularly.

Works as advertised But Overpriced.
Although pricey this made my brew day simple. Just use RO water and add this to the mash 1 package for a 5 gallon batch. I used this to make a Blonde Ale and entered that beer into competition and finished with a silver medal. I've had good results with this my only complaint is I wish it were half the price.

Instructions?
I traded a few emails with the company that makes this stuff because there are zero instructions on how much of this stuff to use. They tell me each packet is for 5 gallons, which I was assuming, but it isn't written anywhere except a review here. After sharing my recipe with them they said two packets were needed for my 12 gallon batch, fit dropped the PH to 4 and I had to add baking soda to bring it back up. Going to try adding it to the mash next time a teaspoon at a time since I have two more packets to use up. I think this product needs a lot more refining and direction to justify $10 on my grain bill. Will not purchase again.

Order change
I messed my order up by not choosing my grains to be left uncrushed, so I called to see if there was still time to change it. There was and come to find out I accidentally ordered an extract kit when I wanted an all grain kit. The gentleman was very polite and helped make my mistakes correct. I always love doing business with Northern Brewer! You guys rock!!! Thanks for being awesome!!! Scott Heighland

Accumash
It seems to work very well considering I have terrible tap water. I just bottled my last brew which was the first time I used Accumash and it tastes much smoother and less minarlly.

Can't edit reviews?
Out of curiosity I re-calibrated my PH meter and it was off by about a point, not sure how that happens but it did. So anyway to counter my own review below I'm not sure if the PH was correct or not. Either way I probably won't be spending $10 a brew session for this product, that's 33% of my last grain bill.

So far so good.
BTW I have no idea what kind of review Cyndi H. just posted here...Baffles me. Anyway... I used it as directed and my mash was consistently stable at 5.45 all through the mash. The resulting beer was very crisp and clean. However, the mix that I order was supposed to have a hoppy finish which I didn't get... maybe after some bulk age and self-cleaning the hops will come out a little more. So far so good.... we will see in a couple of weeks.

I use a Zymatic and have realized some of my issues are due to my water quality. The Z does 2.5 gallon batches. Can I take 5 gallons of RODI water, dissolve this in, then only use the amount of water that I need? Or does it have to go into the dry grain, which means I have to try to get 1/2 of the packet divided correctly?
J S on Jun 21, 2016
BEST ANSWER: Greetings!

Thanks for your question. You can absolutely add this to the water first, then add the right amount of said water to your grains.

Cheers!
Is the product designed for brewing 5 gallon batches? I make 3 gallon all-grain batches and am curious if I should use 3/5 of the packet?
J G on Mar 10, 2016
BEST ANSWER: Yes, the packet is for a five gallon batch size. Make sure you shake the packet really well before you measure out 3/5. The larger particals tend fall to the bottom. Good luck and cheers
First all grain batch coming up this Saturday. I'm trying this product on the fly because I haven't had time to dial into my water chemistry just yet. I understand that accumash is to be mixed into the mash strike water using RO or distilled water. Does this mean the rest of the brewing process (hot water for mashout and sparge water) must use distilled or RO water to ensure the effectiveness of the product or would tap water be fine?
T W on Jan 27, 2016
BEST ANSWER: To get the right concentrations all water used should be distilled or RO water. Good luck on the batch, we'll be here to help if needed!
My apologies regarding my last question, the product I was referring to was 5.2 Mash PH Stabilizer, can Accumash Water Treatment be utilized in conjunction the 5.2 Mash PH Stabilizer or is it a replacement for it?
Mike S. on Jan 13, 2016
BEST ANSWER: As I understand it, accumash would serve as a replacement. The company guarantees ph levels between 5.2-5.7 so you should not need additional support. They recommend the use of either purified or distilled water. If you use tap water I don't believe the ph range is guaranteed
Can Accumash be used with PH5 Stabilizer or is this a replacement for PH5?
Mike S. on Jan 13, 2016
BEST ANSWER: I�?ve used Accumash several times now, & I have found that yes it places you in the 5.2-5.7 range almost always. So there is no need for PH5
This may help it is from accu-mash.com,
ACCUmash is designed to put your mash pH in the desired pH range (5.2-5.7 at room temperature) and as close as possible to the range for the desired subcategory. There is a small chance that your mash pH may end outside of the desired 5.2-5.7. In the event this occurs, you can rest assured a small acid or base adjustment will bring the pH back in, but all the needed components are included in ACCUmash to ensure the correct taste, aroma, and yeast nutrients for the style of beer you are brewing.
I'm all grain and I heat/handle mash and sparge waters separately, do they both need treating before the boil?
B S on Nov 18, 2015
BEST ANSWER: Thanks for the question! I recommend adding the salts to the mash water. You may want to acidify the sparge water so it is below 6 pH but it does not need to be treated. This way the sale will flow into the boil kettle and the resulting water will have the right proportions. I hope this helps! Cheers! James J.
How many gallons of water does each packet treat and what are the recommendations when the OG Exceeds 1.090?
A D on Dec 6, 2015
BEST ANSWER: Hello Mr Brown,

Thank you for choosing Northern Brewer! This product is not to be added directly to water. It is to be added during the mash, and in doing so, it is capable of producing the proper mineral levels in the beer for a 5 gallon batch of wort. I hope that this helps, have a wonderful day!
Which water is the best option and will give you better results Distilled or RO?
B A on Sep 22, 2015
BEST ANSWER: The processes of distilling and RO water are really just two different ways to accomplish the same thing

so either will work equally as well with Accumash.
Can 3 stage filtration water be used?? The two final states is .5 micron (carbon & carbon/MTBE-Clorine-=order-lead-VOCs) removal.
bob b on Sep 18, 2015
BEST ANSWER: Accumash is designed to work with as close to pure H2O as you can get. Unfortunately carbon filtration doesn't even come close to that. Reverse Osmosis water is really best for this product.
Can accumash be used with non sparge systems (breweasy, biab, etc) where total water volume is used instead of just mash volume?
Adam S on Sep 8, 2015
BEST ANSWER: Thanks for the great question! Accumash can be used in this fashion. Only use distiller water for your brewing water and add the accumash to the actual mash. This would still give you the correct mineral and salt profile in the resulting brew and will buffer its pH to the correct range still.
Can acumash be used with partial boil of 3 gallons for a final 5 gallon batch?
jody V on Aug 28, 2015
BEST ANSWER: Accumash is a water treatment for All Grain Brewing. It is meant for the strike water used in the mashing stage. It will not have the intended effect or benefit if used in the boil, partial or otherwise.
