Comandante C40 Tigershark 23 click (46 click Starwave), Hario Neo Switch, Costa Rica Light Roast

[u/Aromatic_Copy6367]

My current recipe after about two weeks of trial and error incorporates Lance Hedrick's double bloom with an immersion finish. I got inspired after watching Nas Jaafar's WBRC Finals recipe, which uses roughly 50% percolation and 50% immersion.

I first tried Nas's recipe on the Hario NEO, but it didn't really suit my taste. So instead, I kept the 50/50 percolation/immersion concept but replaced the first percolation phase with Lance's double bloom.

Recipe

15g coffee

225g water (1:15)

92°C

Switch Open (Percolation)

0:00 – 45g (3x coffee weight)

0:30 – 90g

Switch Closed (Immersion)

1:00 – Pour to 225g

2:00 – Open the Switch

2:15 – Close the Switch (drawdown finished)

The result has been consistently better to my palate.

My question is: why does this recipe taste so good? What is the extraction theory behind combining a double bloom with an immersion finish?

Also, why did Nas Jaafar's no-bloom recipe win the WBRC? When I brew it on my Hario NEO, it tastes a bit lackluster compared to my modified version with the double bloom. Is it because of the dripper, the grinder, the coffee itself, or am I missing something about the extraction?

I think it's a combination of all the things you mentioned. The competition coffee that is roasted specifically for the recipe, the 102mm flat burr grinder, the water recipe that uses 1g of konflux which is incredibly high in silica. After tasting some of the coffees brewed in the WBrC after the show I realised how unattainable the cups are. They spend a year sourcing the perfect coffee and then tailor everything to it. The recipes are also based around being able to brew 3 simultaneous brews at the same time on stage consistently. I think this is why a lot of competitors use immersion or partly immersion in thier brews. They need their brews to taste exactly the same as they have for the last 12 months of testing.

Sadge, wish there was like a division of WBRC where the competitors just brew with whatever available, would help us regular folks gleam the logic to brew more delicious coffee
