Well you're a complete idiot. Everyone knows that silver plated kettles produces coffee which is too bright and tight in the upper range of flavours, making it appear cold. Gold is far better and produces a nice rich and warm coffee, who wants cold coffee? The other thing to watch out for is skin effect, ever drink a cappuccino with skin? Yuck!! Stick to gold mate it's a whole new world, you will be tasting flavours in your coffee which you've never tasted before and didn't even know existed!! This is how coffee should be made and I can put you in touch with someone who can make you a perfect gold plated kettle for only $25,000 or $45,000 with a really good power cable, which will make those flavours zing. BTW, don't listen to professional coffee makers, they think they understand the science of coffee but we all know that coffee flavour goes well beyond what science can tell us. Don't listen to scientific claims of stupid double blind taste tests, just use your own mouth and your own tongue.
