Sure. It's a totally fair question. First of all, you look at the performance of the business overall over the last year and you've got essentially 2 things going on. You have in the single-serve business and in the systems integration, the first part of the year where we were putting in a new accounting and information system in Concord, which is the roast and ground and extract business. You had $5 million to $10 million of cost this year related to those 2 things, which are, for the most part, now out of the run rate. So you look at single serve, where we were basically overrun with orders beyond the equipment, we had to get equipment in. It was late bringing it in. We paid penalties. We suffered the charges of that. We ran 24/7 over time. All of that was in the first part of the year.
In the last 5 months of the year, that business is right on plan, clicking along just like we told you. So if you look at the extract business, flavors, extracts and ingredients and I'll heed your question and keep going, that business is up 70% over the quarter. Same period last year. So single serve is doing exactly what we told you it would do. Flavors, extracts and ingredients is doing exactly what we told you it would do. The hot black coffee business is a very complicated business, where we had a very, very, very good year last year and we've had a bit of a tough year this year. But you take out the demand forecast, now these are the biggest companies in the world, biggest restaurant and C-store chains. We follow their demand forecast.
The gas price spike, the interest rate spike in the summer and the demand destruction that created at their restaurants and in their shelves surprised them as much as it surprised us. So I guess some points in time in hot black coffee, you're going to have periods of time like that. But if we hadn't had that happen to us, you'd be sitting here and saying, well done, you're up 15% year-over-year, tell me more about Conway. It's just life, you just go through it. I've had quarters where we've been pleased and I'm no genius, and we've got quarters when we're disappointed and we're not idiots. It's just part of a commodity processing business where you don't have contractual rights to make people buy a product.
