Von Helman, great additional pictures and info.
When I first started learning about cheese making it was all "Greek" to me, I had no clue what a rennet or other stuff was, it all came with time. For me it was an even harder learning curve as 1) I didn't have a Granny who had been making cheese for years and 2) I didn't have this forum - anyone to ask, just a book. FYI there is a cheese
glossary here.
Basically, your cheese making can be as simple or very complicated. I often think of it like a tree. You start with milk, but then each thing you add or each small process step you take leads to a different branch. And the cheese makers before us over the last 2000-5000 years have figured out 1000's of these different paths to 1000's of different cheeses. Actually I and others on this forum figure out new branches ending in new cheeses all the time, some not so good
.
Also, Francois is a Professional Cheese Maker currently in New Zealand, and his time is short and valuable, and thus yes sometimes his posts are short and concentrated. I sometimes have to read them several times and research them on internet to fully understand what he's saying. Basically for us newbies he is on a higher plain-level like the Dalai Lama or Confucius
.
OK, to your cheese and initial questions:
1) I agree, your additive "Enzymes-coagulant-microorganisms" is a rennet, if you have the brand or any other labelling we could try and find out more for you. To others, while normally separate, is it possible that their additive could actually be a combination rennet and mesophilic starter culture, or can they coexist in concentrated form?
2) Rennet is super concentrated stuff, so yes only a few drops diluted in water before adding to milk are required and yes they are very helpful in cheese making and forming the curd to help release the whey. There is some info
here on rennet and
here on starter cultures. Can you ask Granny how many drops she adds to each gallon of milk? If it is many drops - teaspoon then I agree it is more a rennet type cheese, if it is few drops per gallon then it is more a semi-lactic cheese. There is a
good thread here by members clherestian and Alex on their semi-lactic cheeses. In Alex's first picture, you can see his plain and then ash coated semi-lactic cheeses, in his second you can see his ash coated with nuts or dried fruits inside, an example of what Francoise mentioned in his post above. In his third it looks like nuts and a special mold he's added and grown on the surface, probably
Penicillium candidum.
3) On milling, you've been doing it for years and works well for you and your customers are used to it so yes I'd keep doing that for your current type of cheese.
4) On molds, the idea of adding molds to cheese at first seems strange, but the molds we add are good molds that create nice scent, taste, texture and appearance and are not harmful to humans. These molds can fall into 3 groups, first are starter cultures to acidify the milk, second are secondary cultures to add flavor and texture, and the third are molds which we add to give a surface - rind covering. The first trick is to concentrate or isolate these bacteria, in the past our predecessors brewed all sorts of concoctions, similar to in beer or wine making to do that. Now these molds have been isolated and concentrated by the big
cheese culture type companies and are sold in a huge
range of culture products. For starter cultures used to acidify milk, there are two basic types, low temperature mesophlic and high temperature thermophilic. Yep scientific terms that are hard to say. Instead of manufactured concentrated "pure" cultures, popular substitutes are
buttermilk and yogurt. Some members like Alex only use these, they don't buy these manufactured starter cultures. The second trick for all these cultures is to grow and reproduce them in a controlled method so that other bacteria don't take over and the wanted bacteria don't multiply out of control and you get the cheese your want. That is a whole separate subject.
In conclusion:
- To learn how to make cheese, it is best to stick to one cheese type and perfect it (like you two have done) rather than bouncing from one type to another like I have done.
- Once you have a cheese type perfected, it is always good to take small change steps to see what you get. I like Francoise's recommendations of adding spices or (semi-dried) fruits or like Alex nuts. Or storing in brine (like feta) or storing in oil.
- I would leave new cultures or surface molds to future.
- If you want, you can buy manufactured cultures and molds from on-line cheese making supply stores.
FYI, there is a post here for people new to cheese making.
Lastly, this is almost the longest post I've written so I'm stopping here and hope it helps. To others, please correct me on anything above that is wrong and please add your opinions etc as mine is just one persons.
