That is a kit I plan to keep in production at all times. I have one in bulk now and will start another in the spring. My first batch, I added 3 oz French medium cubes for 6 weeks and it is phenomenal. My current batch has no additions. I am still trying to decide if I will add oak. If I do, it will be a Tuscan Oak Blend of cubes from Midwest Supplies. Here is their description of the product:
Rich and balanced. Medium and heavy toast American oak lends a rich flavor profile of sweet vanilla, toffee, caramel, and a light roasted smokiness. Medium and heavy toast French oak adds a subtle spicy, chocolate character and a bold yet balanced tannin structure.
Hope you like your batch as well as I enjoy mine.
