Pre-Infusion For Increased Flavor
Bonavita has equipped the BV1900TS with a Pre-Infusion feature to let the coffee ‘bloom’ before the brewing begins.
You may have heard the expression “blooming” before but if not I will explain it quickly. I will try to be brief about the chemical reactions of the bloom and why it is so important for a better flavor.
When you pour hot water over freshly ground coffee, CO² or Carbon Dioxide is released.
If more and more water is coming, as it is with most of the average coffee makers, the gasses cannot escape. And when your coffee is not able to “degas”, you may find your coffee to be excessively bitter or taste like acid.
And the purpose of the Pre-Infusion feature is exactly that – to degas the grinds by pre-wetting them before the brewing cycle starts.
Extra-wide Showerhead And Flat Bottom Filter To Promote Even Extraction
The Bonavita BV1900TS is equipped with an extra wide 3-inch showerhead (2¾ inches of Bonavita BV1800).
The wide showerhead and the flat bottom filter work perfectly together to evenly wet the coffee grinds not only in the middle but also along the edges.
And this procedure results in a perfectly balanced coffee, neither over nor under extracted.
Additional Year Of Warranty For Extra Peace Of Mind
As with the BV1800 coffee maker Bonavita also offers a two-year warranty for the BV1900 TS (link to the warranty information provided below).
I really want to emphasize this extra year of protection, since not a lot of (or any?) other coffee maker manufacturers offer it.
