Hey ya, congrats on your first brew experience. Don't let the poor initial results get to you I unboxed a new silvia for work this week, my first shot was a gusher, the second choked the machine and the third was ok but not great. The fourth shot I nailed. it's all about grind and dose. I had the grind dialed in fast, but it took a couple of good dose attempts to get it right. Now getting cracking pours off the machine every time. With more practice and experience, your work area will be cleaner and neater as you factor in cleanliness to your process.
