James, sounds like the smoke is done but I'm sure there are more on the horizon. Here's what you can do to get your temps up, and I'm assuming we're taking F not C.
The
WSM should easily cruise up to as high as 350F, so first decide at what temp you want to smoke.
Now, fill the charcoal ring with a layer of cold charcoal about 25-35mm thick. Evenly space 3-5 fist sized pieces or piles of wood. Then cover that with another 25-35mm layer of cold charcoal and put another 3-5 pieces of wood evenly around the top of that. Open all your bottom vents and dump a half chimney of flaming hot, ashed over charcoal in the middle of your charcoal ring on top of the cold charcoal. Spread it out a little so it doesn't touch the bottom of your water pan. Leave the
WSM unassembled and the charcoal burning like that for about 5 minutes. Then add your barrel, pour hot water to fill your water pan, then put the lid on with the top vent fully open.
Watch your temp climb and when you are within 25F of your desired temperature start closing down your bottom vents. You'll get the feel with practice how much to close them. For higher temps they stay open more. Lower temps, like 225F, they may be only open 5-8mm.
Add the meat when you start to see the smoke change from whitish grey to hints of blue.
As far as refilling your water pan, that's up to you. I don't. I dry smoke with my
WSM a lot of the time (no water), or wet-to-dry smoke (fill and when it is empty I don't refill). BTW, water is best used when you are smoking at 250F or less, otherwise you're just using heat from the fuel to evaporate water. What you want is a low simmer, not a rolling boil. For higher temp smokes, 275 and up, no need for water.
When the smoke is over, remove the meat, close all your vents top and bottom, and reuse the leftover fuel the next time, just knocking off the ash. I have got good at lifting the used charcoal grate and ring, setting it on a couple bricks, dumping the ash from the bowl, then putting the grate/ring with the used charcoal back in the smoker. Add more cold charcoal, wood, and hot charcoal for your next smoke.
Hope that helps.
Love the wine from Spain BTW. One of our favorite wine producing countries. I just might have to open a bottle tonight!
