How Long Does Coffee Stay Fresh? The Real Timeline (and the Fastest Ways to Ruin It)

Best Water for Coffee: Does It Matter? Filtered vs RO vs Tap (Simple Science, Real Results)

Water is the most overlooked variable in coffee—and it can be the difference between a clean, sweet cup and coffee that tastes flat, sour, or “pool-ish.” In this Bilge Brew Show episode, Nate and a very knowledgeable (and very unserious) guest break down what actually matters: chlorine, mineral content (hardness), alkalinity, and why “pure” water like straight RO or distilled often brews worse unless it’s remineralized. You’ll get practical guidance for tap water, filtered water, bottled water, and RO systems—without turning your kitchen into a lab. Show Notes: 00:00 — Why water can ruin great coffee (and why it’s not subtle) 02:10 — Chlorine: if you smell it, you’ll taste it in the cup 04:30 — The four water buckets: off-flavors, minerals, alkalinity, TDS 06:10 — SCA-style water targets (hardness, alkalinity, pH, “no chlorine”) 08:30 — Alkalinity explained: why too high = flat, too low = sharp 10:20 — TDS meters: useful, but they don’t tell the whole story 12:10 — Filter vs RO vs distilled: what each is good for (and where people mess up) 14:10 — Espresso machine owners: scale and corrosion risk basics 16:00 — Quick home test: brew the same coffee with two different waters 17:40 — Bilge Brew tie-in: bitterness variables and water consistency  Links for your show page: SCA Home Coffee Brewers Standard 310-2021 (water ranges summary): https://coffeegeek.com/wp-content/uploads/2023/10/SCAGoldCupStandard.pdf SCA Water Research Report (SCAE/SCAA water targets): https://sca.coffee/s/Water_Research_Report.pdf SCAE Water Chart Report (alkalinity/hardness & corrosion notes): https://sca.coffee/s/SCAE-water-chart-report.pdf SCA article on chlorine & aroma interactions: https://sca.coffee/sca-news/news-from-our-partners/water-and-the-taste-of-coffee Bilge Brew blog (bitterness variables incl. water temp): https://bilgebrew.com/blogs/from-the-bilge-blog/what-makes-coffee-taste-bitter-and-how-to-avoid-it EPISODE: Best Water for Coffee: Does It Matter?

How Long Does Coffee Stay Fresh? The Real Timeline (and the Fastest Ways to Ruin It)

Coffee doesn’t “go bad” the way milk does—but it absolutely goes stale, and most people are drinking coffee that’s already flattened out. In this episode of The Bilge Brew Show, Nate and a fellow coffee nerd break down what “fresh” actually means, why roast date matters more than “best by,” and the three clocks that control flavor: degassing, oxidation, and aroma loss. We keep it simple and practical: whole bean vs. ground, what happens the moment you open the bag, the real enemies of coffee (oxygen, heat, moisture, light), and when freezing helps—or hurts. If you want coffee that tastes alive, this is the baseline. Show Notes: 00:00 — “Fresh” is three different clocks: degassing, staling, contamination 03:40 — Oxygen is the primary enemy; temperature/moisture close behind 06:30 — Whole bean stays fresh longer than ground because surface area accelerates staling 09:10 — Opening a bag speeds staling by changing the package atmosphere 11:00 — Freezing can work if portioned and sealed; refrigeration is usually a bad move 13:20 — Typical “best flavor” windows vary; many guides suggest using beans within weeks, grounds within ~2 weeks 15:10 — Roast date beats “best by” for flavor decisions 17:00 — Related reading: Bilge Brew’s “fresh roasted coffee near me” guide (storage + roast-date red flags) EPISODE: How Long Does Coffee Stay Fresh?

Specialty Coffee Association (SCA) Explained: What “Specialty Grade Coffee” Really Means (and Why It’s Changing)

“Specialty coffee” gets thrown around like it’s a magical stamp of quality—but what does it actually mean? In this episode of the Bilge Brew Show, Nate breaks down the Specialty Coffee Association (SCA): what it is, why it exists, and how it shaped the way the coffee world evaluates quality. We unpack the classic “specialty grade” idea—clean green coffee, defect standards, and the famous 80+ scoring threshold—then explain what’s changing right now as the SCA moves toward the Coffee Value Assessment (CVA), a newer system designed to look beyond a single number. If you buy coffee online (or run a coffee business), this episode helps you spot real quality vs. buzzwords. Show Notes: * 00:00 — “Specialty” as a buzzword vs a real standard * 02:10 — What the SCA is and why it formed (including the 2017 unification) * 04:40 — What SCA actually does: standards, education, events, research * 06:45 — Where “specialty coffee” came from (Erna Knutsen, 1974) * 08:10 — The classic “80+ points = specialty” shorthand (and why it became common) * 10:05 — The shift: SCA’s updated definition + Coffee Value Assessment * 11:30 — CVA becomes official cupping standards; older protocol/form superseded * 13:00 — Green coffee grading and defects (why “clean coffee” matters) * 14:45 — Q Grader program today (now issued by SCA; aligned with CVA) * 16:00 — Shared sensory language: the Coffee Taster’s Flavor Wheel * 17:10 — World Coffee Championships and why competitions influence trends * 18:10 — Buyer checklist: how to spot real quality signals vs marketing Bilge Brew references mentioned in the episode (optional links for your show page): Bilge Brew Coffee Co: https://bilgebrew.com/ Anchor Espresso (Dark Roast): https://bilgebrew.com/products/anchor-espresso Red Alert!

The Tiny Cup That Built Coffeehouse Culture (Plus How to Brew It Right)

Turkish coffee isn’t a “type of bean”—it’s a centuries-old method, a social ritual, and a core piece of coffeehouse history. In this episode of The Bilge Brew Show, we break down where Turkish coffee came from, how Istanbul’s early coffeehouses shaped public life, why rulers sometimes cracked down on coffee culture, and why foam, water, sweets, and even coffee-ground fortune telling are part of the tradition. You’ll also get a practical, beginner-friendly guide to brewing Turkish coffee in a cezve—without scorching it—plus a subtle nod to Bilge Brew’s Red Alert! African espresso blend for listeners who like bold, aromatic intensity. Show notes: Turkish coffee culture and tradition is recognized by UNESCO as intangible cultural heritage, including its role in ceremonial occasions and the tradition of reading fortunes from the grounds. Istanbul’s early coffeehouse history is often traced to 1555 and the Tahtakale area, with accounts emphasizing coffeehouses as community hubs and social institutions. Coffeehouse crackdowns in the Ottoman period—especially under Murad IV—are widely discussed as targeting coffeehouses as spaces of public gathering and political risk. Traditional serving cues (foam as a quality marker, served with water and Turkish delight) and basic preparation ritual are described in UNESCO’s Courier and official travel/culture resources. The grind requirement is extreme—finer than espresso—and is one of the biggest success/failure factors for authentic Turkish coffee. Bilge Brew’s Red Alert! is described as a dark roast African espresso blend with dark berry, citrus peel, cocoa, and warm spice notes—useful context for why it can work as a bold cezve option when ground Turkish-fine.  EPISODE: The Tiny Cup That Built Coffeehouse Culture (Plus How Espresso Took Over) Episode page (canonical): https://bilgebrew.com/podcast/tiny-cup-coffeehouse-culture Espresso Bundle → https://bilgebrew.com/products/bilge-brew-espresso-bundle?utm_source=podcast&utm_medium=shownotes&utm_campaign=tiny-cup-coffeehouse-culture What you’ll learn: - Why espresso became the “social” coffee - How café culture spread (and why it stuck) - What makes a great espresso at home (simple rules) Resources mentioned: - Espresso Ratios (ristretto vs 1:2 vs lungo) → https://bilgebrew.com/blogs/from-the-bilge-blog/espresso-ratios-ristretto-lungo - How to Dial In Espresso (dose/yield/time) → https://bilgebrew.com/blogs/from-the-bilge-blog/how-to-dial-in-espresso-dose-yield-time-simple-method

Siphon Coffee: The Vacuum-Brew Time Machine, Wild History Facts, and a Guatemala Whiskey-Barrel Twist

Siphon coffee looks like a chemistry experiment, but it’s one of the oldest “serious” brew methods in the coffee world. We break down how vacuum brewing actually works, why it used to be a mainstream kitchen staple, and why it stayed alive in café culture. Then we pivot to Guatemala’s coffee history—how it grew from ornamental plants to a major export—and explain what whiskey barrel-aging really is (and what it isn’t). Finally, we talk about why a Guatemala single origin like Bilge Brew’s Drunken Sailor—aged 30 days in a whiskey barrel—pairs perfectly with siphon’s clean, aromatic style.
