Having previously owned and ran a coffee shop, we are keen coffee drinkers, enjoying a variety of coffee types from around the world, brewing coffee daily, including espresso shots for milky coffee drinks. We were very excited to try a new form of coffee brewer that provided a stock of fresh coffee concentrate (similar to espresso) as we did not have to brew a batch each time we wanted some. It did exactly that! Being a cold process there was no danger of scolding the granules. It is important to follow the instructions to understand the processs once you have mastered that you can then start experimenting with different blends and strength. For example we find an 20/80 split with espresso bean works well for our tastes. We are delighted with the product and would certainly recommend it to our family and friends.
