## Overview

CellarScience AD640LB Potassium Carbonate is a 1 lb. unflavored acid neutralizer designed to precisely lower wine acidity by approximately 0.1% per 3.8 grams per gallon. Ideal for winemakers and culinary professionals, it requires refrigeration after use to facilitate potassium bi-tartrate precipitation, ensuring a refined, balanced product. Highly rated and versatile, it also supports alkaline food preparations.

## Description

Lowers acidity levels. 3.8G per gallon will reduce acidity by roughly.1 percent. Wine must be refrigerated for several weeks after application. Tartaric acid drops out as potassium bi-tartrate. Test first on a small amount.

Review: Works for me - I successfully use this to raise the pH of food stuffs. I bought it in February 2024, and my sensitive nose could not detect any smell. I use it for hydrating faba bean protein concentrate and for an alkaline brine for hydrating beans (1 cup dry beans, 700mL water, 28g salt, 7g K-carb; 8–9 hrs room temp + 10–11 hrs in fridge). I do use a citric acid stop bath (4g/2.5c water) for 5 minutes to freshen the beans up and then they taste great. Now you know my secret!
Review: That the quality is good - They help with legs cramps,,,,so we don’t go without them,,,,ask your Dr, about the benefits. You’ll be surprised..

## Questions & Answers

**Q: Can i use this for Nixtamalization?**
A: Yes you can use it but you would need to use potassium hydroxide as well

**Q: What is the percent of potassium?**
A: Potassium Carbonate has a chemical form of K2CO3 with a molar mass of 138.205g/mol. Potassium is 39.098g/mol.  Since you got two K the percent potassium is 2 * 39.098 / 138.205 = 56.58% potassium when measured by mass (or weight).

**Q: How much should i add to 1 galon of water to make a solution similar to general hydroponics ph up?**
A: There is no set answer for this. Type of water will you are buffering will determine what the needed ratio would be. That said this is very strong and even after adding all my needed nutes ( I mix strong, cal mag, 0-10-10,etc.) I use 1- 1½ tsp per gallon which brings my ph into the normal range. I use distilled or rainwater. Its very strong stuff and well worth the savings vs ph up/down.

**Q: Seller, is this k2co3? thanks**
A: To our knowledge, yes, this is.  This is a food grade Potassium Carbonate primarily used in beer & wine making manufactured by Armand Products Company.  You can go to their website for further specs.
