So I took the plung and purchased 100 pods as a mix of the strengths 6, 10, 12 & 16. I like a strong tasting coffee but not bitter. For me the 16 double shot is the crowning glory. Despite the double shot strength the taste for me is not over powering. I'd describe it almost ad chocolately with only a slight bitternes which adds to the flavour. The 12 although a good coffee is probably my least favourite, 10 is a good rounded coffee and should agree with most pallets and finally the 6 is a coffee without kick but creamy and fragrant. If you like a full flavoured coffee usually 9+ then give the 16 a go
