Yeast and bread improvers for reliable fermentation

Baker's yeast converts fermentable sugars into carbon dioxide and flavour compounds, but fresh, active dry and instant formats differ in moisture, handling and storage. Choosing the appropriate product helps make fermentation more predictable.

Ratton Pantry stocks home, craft and professional formats for pizza, bread and enriched dough, alongside selected bread improvers.

Fresh, active dry and instant yeast

Fresh yeast is refrigerated and has a shorter storage life. Active dry yeast is commonly rehydrated, while instant yeast can usually be incorporated directly into flour.

General-purpose instant yeast suits many lean doughs; osmotolerant yeast is designed for higher-sugar recipes. Pizza-specific products and improvers address more specialised handling or consistency needs.

Why buy yeast from Ratton Pantry

Our range lets home bakers, pizzerias and bakeries choose a yeast format and pack size that fits their process and rate of use.

We also provide access to professional products that can be hard to find in ordinary retail sizes, while keeping smaller options for occasional baking.

Choosing yeast and improvers

Select yeast according to the recipe, sugar level, fermentation schedule and storage facilities. Do not substitute fresh and dry yeast gram for gram.

Use bread improver only where it serves a clear purpose and at the manufacturer's stated dosage. More yeast or improver is not automatically better.

Protect opened dry yeast from heat, air and moisture, and keep fresh yeast refrigerated as directed.

Questions & answers

Yeast & Bread Improvers FAQs

What is the difference between fresh, active dry and instant yeast?

Fresh yeast is moist and refrigerated. Active dry yeast is commonly rehydrated before use, while instant yeast can usually be mixed directly with flour. Follow the instructions for the specific product.

Can fresh yeast and dry yeast be substituted directly?

Not gram for gram. Their moisture and activity differ, so use a reliable conversion and account for the particular yeast, recipe and fermentation schedule.

What is osmotolerant yeast used for?

Osmotolerant yeast is designed for doughs with higher sugar levels, where ordinary yeast activity can be inhibited. It is useful for sweet and richly enriched bakery products.

What does a bread improver do?

A bread improver can support dough handling, gas retention, volume, softness or consistency, depending on its formulation. Use only at the manufacturer's stated dosage.

Does using more yeast make dough better?

Not necessarily. More yeast accelerates fermentation but can shorten flavour development and make timing harder to control. Balance yeast quantity with dough temperature and fermentation time.

How should opened dried yeast be stored?

Protect it from heat, air and moisture, reseal it carefully and follow the pack instructions. Large professional packs should only be chosen if they can be stored correctly and used at a sensible rate.
