This is the first time using "refreshe Purified Drinking Water" bottled water. Based on the on-line profile for it, I need to add 2 grams of gypsum, 4 grams of calcium chloride. Since there was no on-line information about chloride and Sulfates, it's a guess that levels will be acceptable. Bicarbonates are in the range and ph seems very low at 4. but I will compensate with ph stabilizer.

Notes

I've been brewing various Scottish Export-80 clones for many years. It started with Kilt Lifter (Four Peaks, AZ) Clone because my son really likes Kilt Lifter and we don't get it here. It has morphed from a straight clone recipe to experimentation recipes, including this one, which focuses on water. I'm using purified water (see water notes), the next batch will use a campden tablet to neutralize the cloramine in our local water supply.

Even though the original intention was to focus on water, I fiddled too much with sugar adjunct ingredients. That is, I added molasses to the boil, which was probably OK, but, I used robust molasses for carbonation sugar. It made the bitter molasses flavor way, way too strong. Never again. I re-bottled (yes, not recommended, but you can do it) with a corn sugar carbonation solution, and after another 5 weeks of bottle aging, it is OK. Still a lot of molasses smell and taste, but it's actually pretty good. Go to http://wildyeast.beer for day-by-day details.
