Lighting transformed my home bar from a functional serving area into a genuinely inviting space — the difference between overhead fluorescent lighting and layered LED with a neon accent piece is the difference between a utility room and somewhere peo
Beer Brewing
Building a 6-tap keezer with a walnut collar was the most satisfying project in my homebrewing journey — the combination of functional brewery capability and furniture-grade aesthetics produced something I’m genuinely proud to have in my home.

Cold Crashing Science: How Temperature Impacts Protein Precipitation
by John Brewster 7 minutes readCold crashing transformed the clarity of my homebrewed lagers once I understood exactly what was happening at the molecular level during the temperature drop — the precipitation of proteins and the settling behaviour of different yeast strains are no

Clarity Ferm vs. Gelatin: The Science of Gluten-Reduced Brewing
by John Brewster 7 minutes readClarity Ferm changed how I approach gluten-reduced brewing — I can now produce beers that my celiac-sensitive friends can enjoy without the harsh stripping effects I used to get from aggressive fining regimens.

The Physics of Carbonation: Henry’s Law and Temperature Equilibrium
by John Brewster 6 minutes readHenry’s Law and temperature equilibrium are the two physical chemistry principles that make beer carbonation calculable rather than guesswork — once I understood that dissolved CO2 concentration is determined entirely by pressure and temperature, the

Yeast Morphology: Why US-05 and WLP001 Aren’t Actually Identical
by John Brewster 5 minutes readThe assumption that Safale US-05 and White Labs WLP001 are interchangeable is one I held for years before running a side-by-side fermentation and discovering measurable differences in ester production, attenuation, and fermentation kinetics between t

Freezing Yeast Banks at Home: The 2026 Guide to Glycerin Stocks
by John Brewster 6 minutes readBuilding a yeast bank with glycerin stocks has extended my brewing significantly — strains I obtained years ago remain viable and available without the recurring cost of purchasing new yeast packs, and my collection of over a dozen preserved strains

The Chemistry of Foam: How to Achieve the “Belgian Lace” Effect
by John Brewster 5 minutes readBelgian lace — the foam ring patterns left on the glass as you drink — became something I actively engineered rather than hoped for after understanding the specific proteins and hop compounds responsible for it.

Managing Residual Alkalinity for Dark Malts: Avoiding the “Roasty Bite”
by John Brewster 6 minutes readResidual alkalinity and its relationship to dark malt roastiness is a water chemistry subtlety that took me several stout batches to fully appreciate — the “roasty bite” in poorly water-adjusted dark beers is a harsh, acrid, almost metallic sharpness

Mash pH and Enzymatic Efficiency: Why 5.2 isn’t Always the Magic Number
by John Brewster 6 minutes readThe “5.2 is the magic mash pH” myth was one of the most persistent simplifications I had to actively unlearn — the idea that targeting exactly 5.
