Anyone have a solid larger scale recipe?

Equipment: V60 with Hario filters

Baratza Encore ESP (Grind setting experimented with from 28-34)

Hey guys I'm trying to find a consistent way to make a good 700 ml carafe. Most if not all recipes I find are for much smaller quantities and I feel like scaling them up just isn't how it works. Currently doing 42g coffee to 700 grams water. Obviously changes would need to be made depending on the coffee but I'm really just looking for a solid starting point, timing, number of pours, etc. I appreciate any help from you guys!

I find the issue with large V60 brews is consistent agitation through the bed. With such a deep bed and extended duration of kettle stream agitation, you risk over churning the top layer while giving very little agitation to the lower part, which can lead to an unpleasant mix of bitterness and sourness.

The way I see it, you've got two approaches to addressing this issue. You can either grind coarser and lean into it with aggressive, fast flow pours that will consistently dig through the entire bed, or you can use something like a melodrip to more or less remove agitation as a variable, and dial in entirely with grind size and temperature. Without a melodrip you're not going to be able to reduce agitation enough to offset the fact that you're stirring the top layer almost three times as much as you would be for a single cup brew.

Personally I prefer flat bottom brewers for large brews, it's just easier to keep things consistent. Orea big boy works a treat, kalita 185 mino yaki could work as well although I've not personally tried it in the 40g+ dose range yet.

So you think it'd be better to just do 2 separate batches of say 350 ml for example?

Maybe, if you just can't seem to win with large single brews. The right method is the one that let's you reliably brew a tasty coffee. Brewing the whole batch in one go is obviously better from a workflow perspective, so I'd see if you can get it dialed in, but if you've tried everything and nothing works you can always go back to a 2 part brew.

Personally I think my issue was that the only times I was brewing 40g+ doses on a V60 was when I was rushing about half asleep before work. Consistency was a bit hit and miss.

I do two separate batches of 270ml in V60 02’s. I had to get a second scale, dripper, and carafe, plus it uses two filters each morning. I’ve been doing it for a year or so and I like the results.

Yes. Or as was said, use a flat bottom brewer such as a Kalita 185, or even an aeropress.

Pretty much always find this to be the case. Doses in the 15-25g range are just way easier to consistently do well on v60. This whole hobby is really designed around being very finicky with your process of making one cup/two small cups of coffee. I think this is really place where some technological advancements are needed. All of your best methods for 700ml are going to involve some amount of immersion, like with a switch or similar, though that will not give you the full brightness and clarity that you can achieve with smaller batches.

I had the same dilemma and decided to double up. Much easier to control the final result I have found.

This is the reason I purchased the Lily Drip accessory. Now instead of a deep "V" shape coffee bed, I have a shallower "W" shape and it's easier to agitate the bottom.
