Made for coffee moments
A simple refill rhythm
FROM OATS TO YOUR FIRST SIP
A small ritual.
A very good morning.
Enzymes help shape what oats become. Start with the texture. Choose your sweetness. Then make a little room for coffee.
Let the enzymes work
Measure your amylase at its working temperature. Add the sweetness or protein step your recipe calls for.
Finish your batch
Follow the recipe’s finishing and straining steps, then cool and store your fresh oat drink as directed.
Make it a moment
A breakfast glass, overnight oats or a carefully poured flat white. Find your favourite way to enjoy it.
Use the supplied formulation’s process conditions. The recipe builder is a trial planner; it does not prescribe temperatures, inactivation or shelf life.
ONE COLLECTION. YOUR KIND OF MILK.
What’s your
oat ritual?
Choose your starting point. You can explore each ingredient before building your kit.
THE HOME COLLECTION
Little bottles.
More possibilities.
Two routes to your oat base. One sweetness step. Two ways to explore oat protein.
30 mL dropper bottles · 100 mL refills · 500 mL café refills
Choose one amylase route for your recipe. Extra enzymes are optional; you don’t need all five for every batch. Dropper and refill formats let you start small and scale up.
STARTER COLLECTIONSTART SMALL. FIND YOUR FAVOURITE.
Your first
oat ritual.
Begin with the everyday pair, or bring protein glutaminase into your coffee experiments. Separate bottles give you control over each step.
The Everyday Pair
Flow Warm + Sweet · 2 × 30 mL dropper bottles
£29 / starter kit
Buy the pair or trio through secure Shopify checkout. Explore the five individual products above first.
FOR THE FLAT-WHITE OBSESSED.THE COFFEE CORNER
Good oats.
Great coffee.
Let’s talk foam.
Your coffee deserves its own oat recipe—at home or behind the café counter. Protein glutaminase changes how oat proteins behave—an interesting route to explore for solubility, texture and foam.
A different way to work with protein.
Protein glutaminase modifies protein side chains without cutting the protein backbone. Published research supports exploring it for plant-drink functionality; results depend on the oat base and process.
OatCraft’s home recipe will need its own foam trials. This is an ingredient added during preparation, with compatible conditions—not a last-minute drop in finished coffee.
OATS. WATER. A LITTLE KNOW-HOW.
Three starting points.
Your own recipe.
Choose a trial recipe, then adjust the batch, oat concentration and measured enzyme additions. Work to the conditions supplied with your enzymes.
The simple oat base
Oats + water + one amylase. A starting point for breakfast bowls and cooking, without the optional glucoamylase sweetness step.
Your everyday oat drink
Oats + water + one amylase, with optional Sweet. Adjust the sweetness step and compare the ingredient cost of your own pour.
A recipe for coffee moments
Your oat base + optional Sweet + Barista protein glutaminase. Compare taste, separation and foam under your actual coffee conditions.
Editable trial plans, not validated preparation recipes. Each enzyme needs its supplied processing, finishing and storage conditions. Silk is a separate guided ingredient for controlled protein-hydrolysis trials.

THE REFILL RITUAL
Keep your bottle.
Keep your rhythm.
Start with a 30 mL dropper bottle. Reorder a 100 mL refill for home, or a 500 mL refill for your café. Measure doses with the graduated pipette in millilitres. Drop size varies; use the mL markings rather than counting drops.
At the illustrative dose, a 30 mL bottle lasts about 14 weeks.
Uses your selected amylase’s calculator settings, with a one-week buffer. A calendar download—not an order or subscription.
A FEW GOOD QUESTIONS
A little more
oat know-how.
Simple questions deserve clear answers.
Do I need all five bottles?+
No. Choose one amylase route to prepare your base. Sweet is an optional sweetness step. Barista and Silk are separate protein tools for suitable recipes. The everyday pair is a simple starting point for trials.
How do I measure with the dropper?+
Use the graduated glass pipette to measure the mL quantity shown in your recipe. A drop is not a fixed unit: the liquid and dropper change its volume. Measure repeated pipette additions if needed; use a suitable graduated measure for larger café batches.
Can I put Barista straight into my coffee?+
Barista is intended for the preparation of your oat base, with the temperature, dose and time specified in the matching recipe. The name doesn’t mean instant foam: oat composition, processing and steaming technique all affect results.
What is the difference between glutaminase and protease?+
Protein glutaminase modifies protein-bound glutamine. Protease cuts protein into smaller peptides. Both can change functionality, but protease treatment needs careful control: excessive hydrolysis may reduce foam stability or change flavour.
Does this make homemade oat milk nutritionally identical to shop-bought?+
No. Enzymes change processing characteristics; they don’t supply the calcium, vitamins or other nutrients added to some commercial drinks. Your final recipe determines its nutritional composition.
How do I order and refill?+
Choose a dropper bottle or refill, add it to your basket and use secure Shopify checkout. Refills are one-off purchases, so you control when to reorder. International delivery is free from £100 equivalent; below that, it is £30 equivalent. Final delivery availability and taxes are confirmed at checkout.
Where can I read about the science?+
For ingredient-level context, explore Amano’s explanation of sweetness enzymes, protein-glutaminase applications, and published plant-protein research. These describe enzyme mechanisms and studied products; they do not validate your final OatCraft recipe.
