Lots of folks suggesting non-aros and vanilla blends for you, as you didn't request that, ha ha.
Molto Dolce, as I am smoking some that is almost 8 years in the tin it came in, and the sweetness has held. The Creme Brule is the bulk for that but without the extra spray of topping, and I don't have experience with that. But I really enjoyed the Molto Dolce with age, as that extra sugar really has penetrated the leaf over the years.
I picked up my tins in a $6 per tin if I ordered 6 tins, so I bought 12, and it has taken me forever to smoke four of those tins, ha ha. But, the paper tins have held up nicely. I have no plans to swap them to more durable jars, as this one isn't one that is going to really go through any fermentation process with age, and it is so sopping wet, that I have no fears of it drying out in another 8 or 10 years.
Maybe, wait for a Sutliff sale.
