Welcome to CS!
To put it as delicately as possible.............. if you want to be taken seriously about your coffee,
don't go anywhere near a pod machine, other than to walk straight past it.
You will wow your guests with a great roast, a decent grinder and something as simple as a press,
google 'how to make coffee with a french press' for technique, brew ratios and steep times.
If you want to go the espresso machine road then do some reading on the various CS threads,
according to your budget. Plenty of people go with box branded machines from the likes of HN/GGs but
I can only advise to purchase from someone who can give you instruction, support
and after sales service. Check out the many sponsors on this site. Don't overlook the importance of a good grinder.
Having the equipment is only part of it and is no automatic shortcut to 'wow' coffee. The most
important factor is 'the hands that make it', in other words your technique.
We are all on the learning curve, just at different places.
Ask questions, enjoy the journey.
