Mugwort porter

I've put on a new brew now the weather has cooled

This is a mugwort porter and the recipe is:

• 18 litres water
• 600g molasses
• 1kg brewing sugars
• a few inches of ginger
• about half a dozen small lemonbalm leaves
• one of those bags used for fruit and veg stuffed full of mugwort

I've submerged the mugwort in the wort, using a cotton bag weighed down with mugs.

The nettle porter last year worked well but had a bit much of alcohol for me.

Update: seems I've pushed my luck too far and the wort is infected. Guess it might've been the tea bag (an old flour sack) weighed down with three mugs.
