    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!

    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

    Cheese making a pleasure!

    Posted by MsEdFun on 18th Aug 2015

    I have numerous food allergies and decided to eliminate as many additives from my diet as possible. I started making my own cottage cheese, cream cheese, and butter with good results. Then, I decided to try my hand at mozzerella. I am happy to say that the rennet I needed, with kosher certification, came very quickly! I was extremely pleased with the service I received, and my cheese is amazing! Thanks you Cheesemaker!

    Posted by Susan Z on 28th Jul 2015

    I needed a kosher rennet to try my hand at making cheese. This worked just fine! I appreciated the fast shipping and the choice of sizes. I can't compare it to anything else, but no problem with this. Yummy Mozzarela.
