Grinder truths, a countertop-friendly superauto, and five ways to cold brew before summer slips away.
August flew by, but the videos are here to stay. This month we covered a lot of ground: the grinder mistakes that might be sabotaging your morning cup, a hands-on look at Terra Kaffe's smallest superautomatic yet, and five ways to make cold brew at home before iced coffee season winds down. Grab a cup and let's get into it.

Coffee Grinding Mistakes You Might Be Making
Blade vs. burr grinders, demystified — why a blade grinder re-chops beans over and over (inconsistent grind, muddy cups, silt) while a burr grinder grinds once at a fixed, adjustable distance for even extraction. Also breaks down conical vs. flat burrs: conical = more body/mouthfeel and the common choice for home grinders (38–40mm); flat = cleaner, thinner cup, faster grinding that matters most in commercial settings. Ends with the take people quote: if you're choosing between upgrading your machine or your grinder, upgrade the grinder first.
Best for: Anyone still using a blade grinder, first-grinder shoppers, and espresso upgraders deciding where the next dollar goes.

Reviewing the Terra Kaffe Demi Fully Automated Espresso Machine
A hands-on review of the Terra Kaffe Demi — a compact (≈7.5″ wide), coffee-only superautomatic with no milk system. Covers the retro-futuristic dot matrix screen, side dial navigation, five drink options, stainless steel conical burrs (same set as the larger TK-02), five grind settings, 1.4L removable water tank, hot water function for tea, and easy cleaning (removable brew unit + guided cycles). The find of the review: a triple-shot option on most drinks, rare in the superauto space. Framed as the upgrade path from pods/capsules for black coffee drinkers.
Best for: Black coffee and americano drinkers, pod-machine upgraders, small kitchens, and anyone who wants fresh-ground espresso without the learning curve (or the milk system they'd never use).

5 Easy Ways to Make Cold Brew Coffee at Home
Five cold brew methods, each scored on taste, time, and effort: (1) flavored/infused pitcher brew (orange-spice with cinnamon and star anise), (2) a machine with a cold brew function — the Fellow Aiden's slow-drip batch in ~90 minutes, the speed winner, (3) filter bag / tea bag steeping, (4) French press immersion at a 1:4 ratio, and (5) the classic mason jar steep filtered through a V60. Closes with ways to reuse spent grounds (compost, soil, body scrub).
Best for: Iced coffee fans, batch brewers prepping for the week, and beginners who want cold brew with gear they already own.

Three very different videos, one common thread: better coffee starts with the right gear. Whether that means finally making the coffee grinder upgrade, letting a superautomatic like the Demi handle the grinding for you, or just putting the French press you already own to work on cold brew — there's a next step here for every setup.
