The classic bottom is a possible bottom to use with the [[Orea Brewer V4|Orea V4]] modular brewing system: > The design that got us here – a semi-restricted bottom that brings with it more intensity with unique balance and sweetness. It goes well with almost any coffee, but it is particularly good with coffee that has been **naturally processed or more heavily fermented**. This bottom can also be paired well with **medium or darker roast** levels.
