Default Instructions
v1.5
Prepare in a 1 liter bottle, or directly in your kettle.
- Add 50 mL (or 50 grams) Hardness.
- Add 0.50 mL (or 0.590 grams) Buffer.
- Add 0.50 mL (or 0.590 grams) Extraction Booster (optional).
- Fill remaining capacity with zero TDS water (about 949 grams).
Buffer Guide
As a starting point, use:
- 0.50 mL Buffer for light roast filter coffee and any tea
- 0.50 mL x2 Buffer for medium roast filter coffee
- 0.50 mL x3 Buffer for dark roast filter coffee and any roast as espresso.
For higher intensity, use less buffer. For lower intensity, use more buffer.
Extraction Booster
The Extraction Booster (EB) is a dropper bottle of mineral concentrate, designed to increase flavor intensity and definition.
Add 0.50 mL Extraction Booster per liter of 1x brew water.
Mineral Composition
All minerals in Empirical Water can be found in natural mineral waters at comparable concentrations.
v1.5
Ingredients
Hardness: Calcium carbonate, magnesium sulfate, calcium chloride, magnesium chloride.
Buffer: Deionized water, sodium bicarbonate.
Extraction Booster: Deionized water, magnesium chloride, magnesium sulfate.
FAQ
Can I mix Empirical Water with tap water, spring water, reverse osmosis or other drinking water?
Empirical Water is an ultra fine-tuned mineral profile. As a result, it's crucial to select a dilution water that contains absolutely zero TDS. Tap water, spring water, and even reverse osmosis water have too much mineral content to be used as dilution water.
What is zero TDS water, and where can I find it?
TDS = Total Dissolved Solids, which are usually minerals. Zero TDS water is water that contains no minerals.
Deionized - Best option. Pick up a Zero Water pitcher and enjoy Empirical Water the way it was meant to be. Zero Water pitchers save money over time compared to buying distilled water. Ideally, feed your Zero Water pitcher or other deionization system with the lowest TDS water you can find, typically reverse osmosis, to conserve the life of your deionization filter/resin.
The recommended long-term solution is an under-sink reverse osmosis unit with a deionization stage.
Distilled - Most grocery stores carry distilled water. Recommended brands: Arrowhead Distilled, Good & Gather Distilled (find at Target), Ice Mountain Distilled
There is quite some variance in distilled water quality, so please try a few different brands to find the one that tastes best.
Reverse osmosis - Low TDS, not zero. Do not mix Empirical Water with reverse osmosis water unless it has been fully deionized.
What is the shelf life of Empirical Water?
An unopened bottle of Hardness concentrate will stay fresh for 1 year. Once opened, it's recommended to use it within a month. The dropper bottle concentrates will stay fresh for 2 months (at minimum), which is the lowest order frequency on offer.
How should I store the provided concentrates?
The concentrates can be stored at room temperature or in the fridge.
What makes Empirical Water different from other brewing waters on the market?
Check out The Key Ingredient in Empirical Water.
What's the difference between the Coffee and Tea Editions?
Differentiating these Editions is a project that's currently in the works. For now, they are the same water, and can brew tea and coffee equally well.
How can I make a lot of brew water quickly?
Reuse the glass bottles as your 1 L brew water mixing bottle. Make several at once to save time.
Can I use Empirical Water in my espresso machine?
empirical water produces a minimal amount of scale in espresso boilers. Check your machine annually for scale buildup.
Can I drink the concentrates?
Do not drink the concentrates before diluting them into brew water according to the instructions higher up on this page.
