APAX Lab Water Minerals for Coffee are mineral concentrates designed to let home brewers and specialty coffee enthusiasts build precise brew water from scratch. Three profiles (TONIK [1], JAMM [2], and LYLAC [3]) each tune a different flavor dimension, and each is available in a 20ml bottle (approximately 30 brews) or a 100ml bottle (approximately 150 brews).
Most tap and filtered water lacks the mineral balance that brings out the best in specialty coffee. APAX Lab concentrates let you start with a neutral base (distilled or reverse-osmosis water) and add back only the minerals that serve your brew. Because the concentrates are made with demineralized water and analytical reagent grade (AR) minerals, the mineral content you dial in is exactly what ends up in the cup, with no background interference from tap chemistry.
Each APAX Lab profile is formulated to emphasize a distinct sensory result. TONIK [1] is built around vibrant acidity, delivering a crisp, intense, and juicy character. JAMM [2] and LYLAC [3] each target their own flavor dimension. Select the profile that matches the coffees you brew most often, or experiment across all three. The usage method is the same for every profile: shake the bottle thoroughly, then add 3 to 4 g/L of concentrate to your brew water, or add 1 to 10 drops directly into the finished cup.
APAX Lab uses analytical reagent grade minerals throughout, the same purity standard used in laboratory applications. That consistency matters in coffee water: lower-grade mineral sources can carry trace impurities that shift flavor unpredictably from batch to batch. With AR-grade inputs, the concentrate behaves the same way every time, so a recipe you develop today reproduces reliably next week.

APAX Lab Water Minerals suit specialty coffee brewers who want precise, repeatable control over brew water chemistry, particularly those using distilled, reverse-osmosis, or very soft water that needs mineral content added back. The two bottle sizes make the concentrates practical for both occasional home use and higher-volume brewing.
APAX Lab Water Minerals are not a water filter or purifier and do not remove existing minerals or contaminants from tap water. They are intended for use with a neutral water base, not as an additive to already-mineralized tap water.
APAX Lab Water Minerals are designed to be added to a neutral water base. Distilled or reverse-osmosis water works best. Starting from a mineral-free base lets the concentrate determine the full mineral profile of your brew water, giving you accurate, repeatable results.
APAX Lab Water Minerals call for 3 to 4 g/L of concentrate added to your brew water before brewing. Alternatively, 1 to 10 drops can be added directly into the finished cup. Shake the bottle thoroughly before each use to ensure the minerals are evenly distributed.
The 20ml APAX Lab bottle yields approximately 30 brews. The 100ml bottle yields approximately 150 brews. Actual yield will vary slightly depending on your exact dose and brew volume.
TONIK [1] is formulated to enhance the acidity of the coffee, producing a vibrant, bright, and juicy character with a crisp and intense result in the cup. Its mineral composition includes magnesium chloride, calcium chloride, sodium chloride, sodium bicarbonate, and potassium bicarbonate.
APAX Lab Water Minerals are made with analytical reagent grade (AR) minerals, a high-purity standard that ensures consistent mineral content and minimizes trace impurities. The concentrates use demineralized water as the base.
