My wife is a coffee lover (in fact she drinks too much), so thinking of presenting her a coffee maker for her birthday. I went in search of a lot of models and at last finalized this model(http://www.bestbrandappliance.ca/en/catalog/product/124677-Miele-CM5100W). But yesterday, I came across an interesting article titled coffee good or bad in one of the sites named authority nutrition. After reading the article, I am bit confused whether I should present her coffee maker or not. Need expert suggestions if too much caffeine is harmful to health.
