    Chymosine double strength

    Posted by Aimee on 13th Apr 2020

    In the past, all the rennet I’ve bought has been amber or brown colored - I’m not sure why this one (which I thought was the same stuff) is clear. Seems less strong than previous rennet I’ve bought from you. I usually use 5-10 drops per two or three gallon batch. With this new rennet that’s resulted in a very soft cure that was difficult to form up . Note from Steve/thecheesemaker: This is the same rennet as before. It is now made without coloring and is the same strength. Coagulation can vary based on temperature and type of milk used. To use, always mix in with a little water then slowly draw across your vat, using 2 pulls. Stirring longer than two or three pulls can disrupt the rennet's coagulation.

    Chymosin: A Bioengineered Marvel

    Posted by Michele Wolski on 19th Sep 2019

    In my senior high school biotechnology class, we begin each year testing various curdling agents to make cheese. We use rennin, chymosin and buttermilk. The chymosin always comes out first for speed (5 to 10 minutes until curdling occurs) but buttermilk takes top place for volume of curds. Students then take the role of a technician to recommend a curdling agent to their "supervisor" and propose further research.

    I'm new to cheese making, but this rennet had worked wonderfully so far. This is a great company to work with as well!

    Posted by Robert T on 3rd Jun 2019

    Works great for my goat cheeses -- mozzarella, feta, and cheddar. I've never had a set go wrong with this rennet.

    Really sets well

    Posted by Sandy on 28th Jan 2018

    Just got this rennet in and have already made several 4lb wheels of Colby with it. It sets the milk up to a good break stage in correct time for my recipes. Thanks, Steve, for the suggestion for this rennet.

    Very good product

    Posted by Ghada on 1st May 2017

    Excellent service. Followed up with an email after I put the order with instruction. I didn't give this product a 5 star because that's the only one I tried so far, otherwise it is an excellent product and the service is excellent too. Thank you
