I just finished up a bottle of Laphroaig's youngest Islay not too long before doing the peat smoked porter and wanted something that had that smoke bite like the scotch. Surprisingly, it just bites you in the face at the first drink, but then settles into the background as you're drinking it.
As for the Thai Basil, I had to idea to do a really light ale that would let the flavor come through and only end up with an ABV of 4-5% so I'd have a nice spring/summer ale to drink on. I have a bunch of Marris Otter I'm going to use as the base, so I was thinking the lightest crystal malt I could find at the LBHS and see what specialties they have that I think would compliment it. If worse comes to worse, I'll just do the Marris Otter and the crystal.
