if you are going to get interested in roasing
Id seriously consider this :
https://www.roastmasters.com/behmor.html
I had this roaster in the earli9er version , and used it for ' Drip " that I roasted , Vac'd
and sent to my sister.
I have a larger roaster for espresso , but that's a different story.
the above place give you 8 lba green coffee sample and has free shipping
Im very loyal to SweetMaria , the the obove is a better deal.
you can do a fine job on 1/3 d of a lbs w this drum roaster
and the initial investment will pay off in no time , and you will have better fresher coffee
that you can taylor to your own taste-profile.
an issue for the espresso ' single shot ' is that its a single shot
and you can't make any adjustments. if carefully designed you might not need to.
having several shots at the same time ?
might be an issue , cool down etc.
but its impressive for sure
Id wait until someone at HomeBarista.com puts it through its paces if I were you.
did I mention how important a very good grinder is for Espresso ?
looking forward to HB.com 's reviews
