Our Bulgarian Sirene (hard white brined cheese, similar to feta cheese) starter makes a delicious sirene that turns out perfectly every time.

Whether you like your sirene crumbly or creamy with excellent taste and great aroma, it’s never been easier to make your own sirene.

Bulgarian Sirene is a type of hard white cheese. It is very similar to the feta cheese variety but has a sharper, tarter taste and the most delicious aroma you can imagine thanks to the presence of lactobacillus bulgaricus lactic acid bacteria.

Each pack contains loose powder mix, in perfect proportions, of a collection of bacterial strains required to make sirene, amongst which  — the ubiquitous lactobacillus bulgaricus and streptococcus thermophilus.

Our Sirene starter is made and packaged in Bulgaria. It is organic and fully natural with no preservatives, additives, artificial colors or flavors. It contains no GMO ingredients and it is gluten free.

Each pack contains freeze-dried live active lactic acid sirene starter cultures. Since the bacteria is grown on organic dried milk powder, the pack also contains a minute (very small) quantity of dried organic milk powder, which is completely consumed by the bacteria during fermentation.

Bacillus Bulgaricus sirene starter is fully natural with no additives, preservatives, artificial colors or flavors. It contains no GMO ingredients and it is gluten free.

It is manufactured and harvested in a strictly regulated sterile environment so it does not contain nor it has been in contact with nuts, soy and other common allergens.

When you introduce the live culture into prepared milk the streptococcus thermophilus bacteria goes into action first and prepares the perfect environment for lactobacillus bulgaricus and the rest of the cultures, which starts multiplying and slowly turns the milk into genuine Bulgarian sirene.

These beneficial, transient bacteria work together in the fermentation process that turns milk into a naturally sweet, smooth, fresh-tasting, super delicious sirene.

The process takes approximately 24 hours to complete.

Storage

Best to store in the FREEZER.

Bacillus Bulgaricus starters are best kept in a cold dry place. Your fridge or freezer works best for this.

You can store the packs in your freezer, at around 0°F (-18°C) or lower, for two years.

You can store the packs in your fridge, at around 40°F (4°C), for one year.

You can store the packs at room temperature for up to a year.

Unfreezing the starter packs and freezing them again (e.g. when using only a portion) is OK to do, even multiple times.

Transporting the packs (i.e. shipping them to you) is perfectly OK and will not damage the live cultures. We use a freeze-dried process that keeps the strains alive even during long trips at ambient temperatures. Once you receive your starter packs – pop them in the refrigerator or the freezer for best storage.

The packs are best used at once. They are packaged and labeled with the grams they contain and the volume those grams make when used entirely in one go. However if you decide to split their content you can of course do so. Take out as much as you need in order to make yogurt, then reseal and refreeze the remaining starter for later. You can see this post for more information about splitting the packs and how much starter to use for different volumes of milk.
