A humble little device that does not do a show or offer original style - but it does make fine coffee.
Positive Product Points
All stainless construction with a great polymer gasket. Light enough to prevent back strains; quick cleanup; excellent filtration; and 40 oz capacity.
Negative Product Points
Very light gauge steel, bordering on flimsy. It's OK, but does not offer a substantial feel. This may be great for folks with arthritis in their hands. The handle is small and will bend at the attachment collar when stressed a tiny bit.
After giving up auto-drip machines for many years of press pot and espresso coffee, I thought I'd try something new. I'd never used a vac-pot before purchasing the (Adcraft/Korea) Food Service Direct model. It has a capacity of 40 oz. (1.5l).
Zeroing in a suitable grind wasn't too difficult. I use something slightly finer than I would with a french press. Following time honored posts, I use 1 rounded tablespoon per 4 oz. water. This produces a full-bodied cup. Moving down to 1T per 6 oz. was a bit weak tasting for my preference. The pot is suitable to boil water in - just. A few minutes of northbound bubbling followed by a one minute drawdown produces a fine cup of coffee. I do not detect any metallic taste.
All 18-8 stainless, it cleans up in a minute in the sink. Don't stress the handle too much when washing because it feels like it might bend and break after a while. The all-metal filter (offset holes on two small convex disks) keeps any grounds out of the coffee. There remains only the slightest amount of fine sediment; it is not evident in any but the last cup poured. The gasket is substantial and seals perfectly. Less the gasket, there would be no dishwasher problem with this pot.
I cannot compare the performance to any other vac-pot, but I am impressed with this little guy. It isn't bulletproof, exactly, but it is tougher than glass and I expect it would last a lifetime if not run over with a car.
