A hard cheese story

[TrickiDicki]

Hi guys
I've been making camembert for a while but the last 2 or 3 batches have turned out much harder than usual. Any ideas why this might be?
Could my rennet be too old (it does need replacing...)?
It is summer here - could it be too warm? Could the milk be too rich?
I've added a splash of vinegar to my brine solution - could that be adding too much pucker factor?

Thanks for your help!

You mean they do not soften up and go runny ?  Or they star out harder but turn out normal after a little more aging?

Don't have a particular answer to offer, but do want to welcome you to the forum. And a question - sounds like you are brining your cams. I've never tried that; I also dry salt them - but I don't know that it would make any difference ... ??

The first batch I thought the cellaring temp was a bit high (in the basement during summer). The mold skin formed in about a week where it usually takes 10-14 days, so I put the hardness down to that. I've now changed to using a temperature-controlled fridge (11-13C).
The second batch I was very excited about, trying to make a more Brie-like cheese. I allowed the curds to ripen at about 32C/89F (which is lower than I usually use) and cut them fairly large, gentle stirring and ladelling only. But these have gone very firm in the 4-5 days since making. I added Geotrichum for the first time to this batch.
The third batch followed a similar method to (2), made 48 hours ago. Feeling a bit squishier, a bit better but still on the firm side. This is my first attempt at Cambozola so I *really* want it to work!!!

This is the starter culture I've been using and haven't had problems before. http://www.cheeselinks.com.au/products/cheese-starters-mould-spores-and-aroma-cultures/type-farmhouse-starter

Many thanks.

I've always brined my cams, haven't had any issues before. I am interested to try dry salting as it should be quicker.

Do you use raw milk and high fat milk? My raw milk cams, especially if I put extra cream in it, get hard before it soften. I found that they need around 6 -7 weeks ripening while PH milk only need 4.

I would guess that it has the same result. Dry salting is not quicker in one sense - I generally salt my cams over about 48 hours. But it is a lot quicker and easier in another sense - I put 1/4 of the salt on the top, and let it sit for 12 hours; flip and put 1/4 of the salt on what was the bottom but now is the top, let it sit for 12 hours; repeat twice more. On the last flip & salt, I go ahead and put it in a ripening box in the cave. It doesn't matter if it is more or less than 12 hours, and only takes a couple of minutes to do the salting, so this way I am not tied to the cheese the way I would be if it were in brine - waiting for just the right amount of time to take it out.

So, just to be clear: I make a set of cams one evening; let them continue to drain until the following evening. Then I salt one side. The next morning, I flip and salt again. That evening, flip and salt again. The next morning, flip, salt, and put in the ripening boxes in the cave.

Thanks for the input, Ann. It is high summer here in Oz so the milk is at its richest. I always try to use the richest organic/biodynamic milk available, which was the case here. Certainly there was a lot of curd when they were hooped, indicating high solid content.
I've now got a 'cheese cave' rigged up so I have better control over the temperature and will let the little beauties sit for a few weeks and see how they progress.

A cheese does usually get a little firmer after a few days . How many cheeses did you make before this started to happen?  It has been  my experience to get a firmer rennet set in spring summer  so you could be experience this.

This is why I ask how many cheeses you made with the same recipe before this started and were they with in the last few months.?

There is a bunch of other posibilities but they are harder to pinpoint

Also  how firm are they ?

[TrickiDicki]

They don't feel like they have the usual 'give' when turning them. I've made many batches in the past and the batch I made for Christmas had a decent consistency, so these batches have been noticeably firm and out of the ordinary from early in the maturation.

[Gregore]

Couple of ideas are

Acid dropping a little low before salting ( could be caused by temp being higher in room when in molds )
Too much rennet
Too much stirring ,cooking , too long , too hot ,
Shorter floc time ( using clean break instead of floc multiplier)

There may be a few other that I forgot.

[TrickiDicki]

I think that higher-than-normal room temperature is the most likely culprit. In which case I'm guessing things might just take longer on the maturation side.

[Gregore]

Unless it is a lot dryer than  it should be,   it will  not take very much longer .
