My Pyrex 4 cup glass perculator

Author | Marc Wortman

Question: Hi Marc, Can you help me to make better coffee in my pyrex 4 cup glass percolater? It tends to be weak, too light in color and burned, I think. Really bad!! Thanks so much, Wendy Burke.

Answer: Wendy, I appreciate the question but I’m afraid you won’t like the answer. You can read more about my opinions of the electric perculator, but suffice it to say, a weak and burned flavor is typical of the perculator, regardless of the construction or whether it’s electric or made stove-top. The glass perculator is a unique and interesting feature in the kitchen and unfortunately, makes coffee the same as any perculator: weak and burned. The coffee has been boiled in your perculator, and the drip brewer was designed to compensate for the shortcomings of the electric perculator which was an improvement over the stovetop perculator. The glass perculator may be unique and interesting, but left behind in the ways of making good coffee at home.

Can a perculator make good coffee?

Author | Marc Wortman


Question: I recently purchased an electric perculator and I’m not sure how this differs from the drip coffee I typically brew but it seems watered down even though I use the same ratios. Is this typical for this type of process and what would give me the most flavor out of a brew. I hate to have wasted money on the product but should I go back to a regular drip machine?

Answer: My suggestion would be to go back to the regular drip machine. Unfortunately, I hear all too often from perculator owners that say using the same amount of coffee leads to a weaker coffee in the cup from using the drip brewer. The percolator is almost like charcoal grilling: it has die-hard lovers but has otherwise been relegated to camping trips. The percolator violates what for some is a rule of good coffee, and that is boiled coffee is spoiled coffee. The percolator heats the water to boiling, and forces it through a tube onto the ground coffee in a filter. It all happens too fast for the water to properly absorb enough flavor from the coffee, so this semi-brewed coffee is also heated to the point of boiling and forced again through the tube onto the ground coffee. This is repeated enough that you are boiling coffee, and doing it more than once. While I’m no chemist, I believe this is why people complain of a weaker coffee from the perculator.

New coffee maker is making coffee worse

Author | Marc Wortman

Question: I bought a new drip coffee pot, and now, using the same coffee, I have a weak, nasty tasting coffee with an oil slick.

Answer: Tough to know all the possible reasons why your new coffee maker is making coffee worse without more details on your new maker. The easiest advice is that you should run a ‘cleaning cycle’ through your brewer of two parts water and one part vinegar. Following that, a couple plain water cycles to make sure the vinegar is rinsed out. Vinegar is a powerful cleaning agent, and might eliminate with the nasty taste. Because your coffee is also weak, that could be that the coffee maker is not strong enough to properly extract coffee solids out of the ground coffee and into the pot. You could check the wattage of your new coffee maker. Anything close to 1,000 watts is acceptable, more than that is a good brewer, less than that is not optimal. The oil slick problem might get solved with the vinegar wash, but could also be a defect with the machine. If the wattage is close to 1,000 watts and your vinegar cycle doesn’t improve the coffee, I’d say your coffee maker is defective and should be returned.
