Presto 02811 12-Cup Stainless Steel Coffee Percolator

The original version of this article was a 2009 product description of the Presto 02811 12-cup stainless steel percolator that took the marketing claim of “100% stainless steel construction” at face value. Several readers, most notably Emory in 2013 who called Presto’s customer service line directly and got the engineering answer, established that the claim is not quite accurate: the perk well (where the water heats) is aluminum, and the perk tube and basket are stainless. The exterior is stainless. The original article was technically correct that it had stainless-steel components, but incorrect to call it 100% stainless. That correction matters because some buyers specifically want all-stainless water-contact surfaces, and the Presto 02811 does not meet that bar. The rewrite below incorporates Emory’s correction and the other practical brewing insights from fifteen readers across the comment thread.

The stainless steel question

Reader susan (2013) asked in the comments whether anyone else had noticed that the Presto 02811 was not actually all stainless steel. Reader Emory then called Presto Industries directly at 800-877-0441 and got the manufacturer’s answer: the perk well (the chamber at the bottom of the percolator where water heats) is aluminum. This is what allows the unit to heat water quickly. The perk tube that carries hot water up to the basket is stainless. The basket itself is stainless. The exterior shell is stainless. But the water makes contact with aluminum at the heating chamber before traveling up through the stainless tube to the basket.

For most buyers, this distinction is not a deal-breaker. Aluminum cookware has been studied repeatedly for decades and the health concerns historically attached to it have not borne out under modern epidemiological scrutiny. The reasons people prefer all-stainless are personal preference, taste perception (some palates detect a slight metallic note from aluminum water-contact), and durability over decades. If those matter to you, the Presto 02811 does not deliver what the marketing implies.

Genuine 100% stainless steel electric percolators are harder to find at the Presto price point. The all-stainless Cuisinart PRC-12 and the older Farberware “Yosemite” are among the few mass-market options where every water-contact surface is stainless. Both cost more than the Presto.

Brewing temperature: not boiling

The biggest factual upgrade to the original article comes from reader NewsView’s 2010 measurement of brewing temperature on the Presto perc. NewsView measured roughly 195 F (90 C) at the basket during perking, which lands squarely in the SCAA Golden Cup brewing range. This is significantly cooler than the rolling-boil temperatures (212 F / 100 C) that older percolators were known for and that made the brewing format unfashionable among specialty-coffee drinkers in the 1990s and 2000s.

Modern electric percolators including the Presto 02811 use a thermostat that interrupts the heating cycle before the water reaches a true rolling boil. The “perking” sound is real but the temperature stays in the proper brewing window. This is the engineering reason that modern percolators can produce a meaningfully better cup than their grandfather’s stovetop perc did. The format itself was not the problem; the temperature control was.

NewsView’s longer comment (well worth reading in the thread) makes the case that critics who have not tried a modern electric perc are often comparing it to memories of stovetop perks or older boiler-style electric units that ran much hotter. The Presto 02811 in 2026 brews coffee that any drip coffee drinker would recognize as legitimate, not as the burned bitter mistake percolators were caricatured as.

The “grounds in the cup” problem and how to fix it

The most common complaint in the comment thread, and probably the most common reason new percolator owners give up on the format, is grounds ending up in the brewed coffee. The fix is mechanical and works reliably:

• Wet the basket thoroughly before adding grounds. Reader Rena Watson (2011): “There are absolutely NO grounds if you thoroughly wet the coffee receptor prior to putting the coffee in it. It really works.” This is correct and is the single most effective fix. The wet basket sides hold the grounds in place during the percolation cycle; a dry basket lets the grounds shift around and migrate through the basket holes.
• Check and clear the basket drain holes. Reader tim (2011) suggested a round toothpick to clear blocked drain holes in the basket bottom. Over time, coffee oils and fine particles partially clog the holes; this changes the flow rate and pushes some grounds upward. A regular toothpick clearing once a month keeps the basket flowing properly.
• Use the correct grind. Drip-grind coffee is too fine for percolators; the fines pass through the basket holes regardless of how well you wet the basket. Use “percolator grind” pre-ground coffee or grind your own at a coarse, kosher-salt texture.
• Use a paper filter as backup. Cut a #4 cone filter with a center hole for the perk tube and seat it in the basket before adding grounds. This catches any fines that escape and produces a cleaner cup.

Reader Mike (2010) had a more unusual variant of the grounds problem: coffee grounds floating up and out of the basket entirely, with wet coffee grounds visible on the outside of the basket and under the lid. This typically means too much coffee in the basket (the grounds expand as they wet and overflow), too little water (the percolation cycle is too aggressive for the water volume), or a defective basket lid that is not sealing properly. Check those three things in order.

Coffee ratios and grind for the Presto 02811

The Presto 02811 brews 4 to 12 cups; the “cup” is the standard percolator 5-6 oz / 150-180 ml serving size, not an American 8 oz mug. Standard ratio for the unit:

• 4 cups (minimum): 4 tablespoons (about 20 g / 0.7 oz) of medium-coarse ground coffee.
• 8 cups: 8 tablespoons (about 40 g / 1.4 oz).
• 12 cups (maximum): 12 tablespoons (about 60 g / 2.1 oz). About 3/4 cup ground coffee.

The “perking time” is roughly 1 minute per cup, so a full 12-cup pot perks in about 12 minutes from cold start. The indicator light tells you when perking has stopped and the thermostat is holding at serving temperature.

For grind: medium-coarse, like kosher salt or coarse sand. Test the result; if you get sediment, go slightly coarser. If the coffee is thin or weak, go slightly finer. The Presto basket holes are larger than drip-coffee filter pores, so finer grinds always produce some sediment.

Brewing tips from the comment thread

• The salt trick (reader Jacob, 2011): a small pinch of kosher salt mixed into the grounds before perking takes the edge off the slight bitterness that percolator coffee can have. This is an old southern home-brewing tradition and it actually works. Try it once if you find your perc coffee a touch bitter; if you like the result, keep doing it.
• Empty the basket promptly after perking finishes. Leaving spent grounds in the basket while the pot holds at serving temperature continues to extract bitter compounds from the grounds into any residual moisture, and over time these flavors contaminate the next batch.
• Do not lift the lid during the perking cycle. The cycle depends on pressure and steam dynamics; opening the lid disrupts the flow and can leave you with weaker coffee than the recipe called for.
• The keep-warm function holds at safe brewing temperature without scorching, but coffee held more than 30-45 minutes loses its aromatic complexity and starts tasting flat. For best flavor, brew shortly before serving.
• Made-in question: reader Eva and Katherine Dordevic both noted the unit is made in China. This is true of essentially every electric percolator at this price point in 2026; the country of manufacture has not been a meaningful differentiator since the early 2000s.

If you want an alternative

The Presto 02811 is still in production as of 2026 and remains widely available. If you want alternatives that address the specific concerns above:

• Cuisinart PRC-12 ($100-$120) is the genuinely all-stainless electric percolator pick. Every water-contact surface is stainless including the perk well. 12-cup capacity, similar brewing time to the Presto. Worth the upgrade if all-stainless construction matters to you.
• Hamilton Beach 40614 ($30-$45) is the budget alternative. Brews 4-12 cups with similar mechanics to the Presto. Build quality is lower than the Presto, but at half the price the trade-off is acceptable for occasional use.

Frequently asked questions

Is the Presto 02811 actually all stainless steel?

No. The perk well (water-heating chamber at the bottom) is aluminum. The perk tube and basket are stainless. The exterior shell is stainless. Confirmed by reader Emory in 2013 who called Presto directly at 800-877-0441. If you specifically want a percolator with all-stainless water contact, the Cuisinart PRC-12 is the more accurate fit for that requirement.

What temperature does it brew at?

About 195 F (90 C) per reader NewsView’s measurements. This is within the SCAA Golden Cup brewing range and significantly cooler than the rolling-boil temperatures older percolators were known for. Modern electric percs use thermostats that interrupt the heating cycle before true boiling.

Why do I get coffee grounds in my cup?

Three usual causes: drip-grind coffee that is too fine for percolator brewing (fix: use perk-grind), dry basket that lets grounds shift during perking (fix: thoroughly wet the basket before adding grounds), or clogged basket drain holes (fix: clear with a toothpick once a month). All three together usually produce a clean cup.

How long does it take to brew 12 cups?

About 12 minutes from a cold start. The “one minute per cup” rule holds across the brew range. The indicator light shows when perking is complete and the keep-warm cycle begins.

How much coffee for 12 cups?

About 12 tablespoons (3/4 cup, roughly 60 g / 2.1 oz) of medium-coarse ground coffee for the full 12-cup pot. Adjust up or down by a tablespoon based on strength preference.

Should I use paper filters?

Optional. The basket is designed to work without paper filters when you use the correct grind and wet the basket properly. Paper filters become useful if you want a cleaner cup, if you are using slightly finer pre-ground coffee, or if your basket has degraded over time. Use a #4 cone filter with a center hole cut for the perk tube.

How do I descale the Presto?

Fill the unit with 50/50 white vinegar and water, run the perk cycle without coffee, then run two cycles of plain water to rinse. Do this every 1-3 months depending on water hardness. Mineral buildup on the heating element slows brewing and changes the brewing temperature over time.

Why this article changed

The original version of this article was a 2009 product description that took the “100% stainless steel” marketing claim at face value. Reader Emory called Presto directly in 2013 and confirmed that the perk well is aluminum; reader susan flagged the same issue in the same thread. Reader NewsView measured the actual brewing temperature in 2010 and showed that modern electric percs brew within SCAA range, not at rolling boil. Reader Rena Watson identified the wet-the-basket fix for the grounds problem; reader tim added the clear-the-drain-holes technique; reader Jacob shared the southern salt trick. Reader Mike (2010) raised the floating-grounds problem and we now have a diagnosis for it. This rewrite tries to consolidate everything fifteen readers contributed over more than a decade. If you have additional tips or corrections, the thread is still open.
