I have a homegrown coffee tree in Toronto, Canada. It loves summer-time on my deck, but always took a beating every winter (dropping a lot of leaves) until last year... I bought full-spectrum lighting in its sixth winter and finally got blooms last May. I harvested nearly 40 cherries in the past couple of weeks. They're dried and hulled now and I'm going to roast them in a cast iron pan - I have about 10 grams in raw dark green beans. Think I'll get an espresso out if it? And can I expect a higher yield next year?
