Cold Brew Mastery (Guide)

One master recipe, a dilution matrix, and six drink builds: two weeks of better iced coffee from a jar on your counter.

Who this is for: anyone paying cafe prices for cold brew, and home brewers whose batches come out weak one week and bitter the next. Who it is not for: espresso-first people; the Dial In in 7 Days course is your lane.

What is in the guide, 3 print-ready pages, instant PDF download:

• The master recipe: the 1:8 concentrate ratio by weight, coarse grind, and the 12 to 18 hour steep window, with a worked example batch
• A vessel table (mason jar, French press, filter pitcher, bucket and brew bag) so you brew with what you own
• The dilution matrix: five concentrate-to-water starting points from strong-and-bold to hot-in-a-hurry
• Flavor troubleshooting for weak, bitter, sour, and flat batches, with the exact variable to change next time
• Honest storage guidance: about 2 weeks for refrigerated concentrate, and why to dilute by the glass
• Six drink builds: over ice, with milk, cold brew tonic, an affogato-style float, a scaled party batch, and the iced latte hybrid

The math: two cafe cold brews cost more than this guide, and one batch from page 1 pours about five glasses.
