Best Grinder Setting for V60 Pour Over Brewing?

Coffee preparation techniques besides espresso like pourover.

Hello, my name is Dal Moody. I use a Baratza Forte-BG grinder for my pour over brewing. It is set at 7D. I am wondering what setting other Forte-BG users use? I use a V60 brewer with 26 grams of coffee. Thanks.

I have a Vario and I would consider 7D to be a little coarse. For V60s I'm in the 4M range, but what kind of pour-over are you doing as some are better with coarser grounds.

A tiny bit coarser than when astringency starts to appear in the finish. I find it varies a bit by coffee and roast.

https://baratza.com/grinding-tips/ suggests 4M / 5M for their steel / ceramic flat-burr grinders.

Andrew, I'm making a single cup pour over with the V60 (26 gr) using Costa Rica La Minita Tarraza coffee roasted medium, agtron color 65, roast drop temp 408 F.

that's a fairly light roast and I would try and grind finer. as Jeff suggests keep going until its astringent then go up a touch coarser where the astringency is not present. in this you establish the extraction ceiling before negative flavours are present.

what water/coffee ratio are you use? how fast is your the total brew? whats your impression of the cup?

Coffee Extraction dated 5/23/2020. V60 Forte-BG setting 7D. Brew Temp 203F. Brew time 3:14. 26.5 gram coffee. 425 grams water. Brewed coffee wt - 367 gr. TDS: 1.47, 1.57, 1.58. Extraction: 20.36%, 21.74%.

Here is a curve ball for you to consider. Mostly I batch brew using a Bunn Pour Over Batch Brewer. Coffe Extraction dated 8/30/2020. Forte-BG setting 7D. Brew temp 200F. Brew time 2:39. 35.8 grams of coffee. 572 grams water. Brewed coffee wt 509 grams. TDS: 1.49, 1.54, 1.37. Extraction: 21.18%, 19.48%.

I had better extraction results using the V60 pour over with a grinder setting of 7P. Ideal balance.

you seem to have all the data. How are you measuring extraction? SCA says the gold standard is 1.15-1.35% TDS and 18-22% extraction but that data is based on 60-year-old studies nor does it factor the interstitial fluid which decreases total TDS and increase total extraction up to a full percent. Decreasing TDS is as simple as adding a bit of water to it but increasing typically means a larger dose or a finer grind but heat and a blooming technique are important as well. The goal is to get as high as extraction as possible without unpleasant astringency so if you have a VST then I would take advantage of it and grind finer and finer until you hit that extraction ceiling then you know what you're own gold standard is.

Use less water. We like 25/375. 3:30 draw down. Coarse sand grind. I'll have to remember the astringent tip on grinding. thanks

Disagree- go finer and use more water! I go SUPER fine and am mostly doing 25/500 right now

15:1 vs 20:1. Heck, my wife likes 10:1
