00:00 - Intro

00:22 - Determine Your Extraction Yield

00:33 - Pull Your First Shot
Remember to taste your espresso and look for bitterness

00:48 - First extraction
Under extracted

01:45 - Adjust Your Grind Setting
Set up a fine grind setting and look for bitterness in the espresso. Once you find the bitterness you know that you’ve over extracted your espresso. At that point move slightly coarser again to find the ideal extraction for you coffee.

02:11 - Tip 1
When you change your grind setting remember to purge a bit of your coffee before extracting to avoid leftover grounds inside the grind chamber

02:26 - Tip 2
Use the sizes of the circles on the Super Jolly V Pro to determine which way to adjust, from fine (small) to coarse (large).

02:54 - Tip 3
Quickly set up the exact timing for your desired dose amount using the manual mode on the Super Jolly V Pro.

03:43 - Second extraction
Keep going finer

04:29 - Tip 4
Make big enough adjustments to feel enough of a difference in your espresso.

04:55 - Third extraction
Almost there: more body and bitterness. You can now slowly move into a coarser grind size until you find the sweet spot.

By following these steps, you’ll be able to fine-tune your espresso recipe to perfection, ensuring a rich and balanced flavor every time.
