I waited to check my inventory to give an accurate answer.
1. My cellar is more wide than deep
2. I have 138 (Or 139) different blends which I have purchased over my 17 months of active pipe smoking.
3. Two different pivot tables giving me two different answers for the no of blends, (138 vs 139) but I am not motivated enough to find out which one is correct. I do believe 139 is correct and the other Pivot table is not distinguishing between Edward G Robinson made by Sutliff and made by HU
4. The total amount in sealed tins and jars cellared is 27.4 pounds
5. There is another 5.1 pounds which I have open right now, or had opened earlier smoked a few bowls and then jarred. How much tobacco is in this category is very difficult to estimate but putting some ball park here, I estimate total smokable cellar I have is about 31.1 pounds
6. I have smoked about 8.6 pounds (Also an estimate) of tobacco over 17 months so my monthly consumption is estimated to be between 6-9 ounce
7. It is very difficult to predict how long my cellar would last, but definitely good for 5 years
