Dial in a better cup.

Bloom is a brew journal for coffee at home. Log what you brewed, brew along with your pour plan, and let each cup tell you what to change next.

Coming soon to the App Store See how it works
Bloom's Brews tab: a journal of this week's brews, each with its dose, water, ratio, grind, temperature and time, a rating and a taste note.
Dose

Slide it. At 1:16, that’s 280 g of water.

From the bag to a better cup.

Bloom follows the way you already brew, from picking the coffee to the cup you’ll want to make again.

  1. Put the bag on the shelf.

    Snap the bag and Bloom cuts it out as a sticker. The roaster, origin, roast date and grams left stay with it, and resting bags tell you when they’re ready.

    The Bags tab as a shelf of photo stickers: three resting bags on top, ready in three days, and eight bags on the shelf below.

  2. Log the brew in seconds.

    Each brew starts from your last one with that coffee, so you only change what changed. Every number is a ruler you slide with one thumb.

    The New brew sheet, prefilled from a recent brew: coffee, grinder, method and brewer, with the dose ruler at 17.5 g.

  3. Brew along, step by step.

    Build a pour plan from bloom, pour, swirl and wait steps, then tap Start. Bloom calls every pour, big enough to read with a kettle in your hand.

    Step 1 of 5
    Bloom
    50g
    +50 g this pour, 0:45 left
    Next Pour
    0:00

    A 17 g, 255 g V60, running six times faster than a real brew.

    The guided brew, step 4 of 5: pour to 255 g, 102 g this pour with 19 seconds left, swirl next, and the brew timer at 1:31.

  4. Taste it, then know what to change.

    Mark the cup from sour to bitter and Bloom tells you what to try next time, or that you’ve found it.

    How did it taste?
    Slightly sour Go a bit finer or a touch hotter next time.
    A brew's detail page with a photo of the cup, its recipe compared with the last brew, and the verdict: balanced, dialled in, keep this recipe.

  5. Keep your go-to.

    Mark your best brew and it becomes the bag’s go-to recipe, one tap from brewing it again.

    A bag's page showing days off roast, grams left and brew count, its go-to recipe card and a Brew with this button.

Made for the way you brew.

Insights: 49 brews in the last 8 weeks as a bar chart, and a taste summary that reads mostly balanced.

Insights, not a dashboard.

See how often you brew, which way your cups lean, and the coffees and origins you come back to.

The share sheet: a brew card with a photo of an espresso, the coffee's name, rating and taste, and buttons to copy a link or share the card.

Share the cup.

Turn a brew into a card with your photo and notes, or send the recipe as a link that opens straight into Bloom.

A grinder's page with its total brews, coffee ground and average dose, above its recent brews.

Every grind setting, kept.

Add your grinders and every brew remembers its setting, down to a tenth of a click.

Classic pour splits
Start a pour plan from an even split, the 4:6 method, Hoffmann’s six pours or Scott Rao’s, then make it yours.
Espresso, too
Log dose, yield and time for every shot, and tag it with your machine profile.
A ratio calculator
Solve for water, coffee or ratio, whichever two you already know.
Rest days
Set a rest period for each bag and Bloom tells you when a fresh one is ready.
The brewers you own
V60, Chemex, Kalita Wave, Origami, Hario Switch, Clever Dripper, April, Orea, Kono, AeroPress, French press and more.
