update 10/5/2020. Adding additional process notes. When base beer is hald fermented add the blueberries. I get frozen blueberries from the grocery store, thaw overnight, then blend into puree in the blender. I used 6lbs blueberry for this batch but that is probably too much. It tasted like juice instead of beer. Probably next time use 3 or 4 lb. Scrape the vanilla bean and soak in small amount of vodka with lemon zest for at least 2 days before adding to the beer.
Update 11/26/18 : brewed this last night, decided not to go with the belgian yeast - it was really old, i wanted to make a week long starter to prove it was still viable and the number of healthy yeast in there is probably low. anyway just went with the 1056 now we will just call it a blonde ale i guess. teal suggested that blueberry muffins often have lemon. plenty of ways to do this but i think i am going to zest 1 lemon and add it to the vanilla bean vodka mixture for a couple days before going into secondary. decided the amount based off of this discussion : https://www.beeradvocate.com/community/threads/how-many-lemons-zest.15966/#post-249484
also considered using dried peel. would have to order or go to brew store for that though so we'll try the zest.

10/24/2018 : copied from 2016's trustmonkey belgian blond. removing cane sugar and LME, changed from pilsner malt to 2row, adjusting efficiency, adding some base malt to make up for removed sugars but also to increase abv to around 7. adjusting crystal malts to match original recipe percentages. switched to only hallertau for simplicity. im seeing sample belgian blonde with 5.6AAU for 60 mins (https://byo.com/article/belgian-blond-style-profile/) so ill go with about that, and add some flavoring hops as well. not sure how much blueberry to use yet......rb10242018
--------------------
copied from 2015's blinde recipe. came out with 5 gallons exactly but was under on gravity - 1.044 (without the sugar), wanted to hit 1.051. By chance I have some Pilsen LME so I will add enough to add 7 pts. Wort has been chilling for one day while yeast starter....starts. Adding the LME and pitching tonight (night after brew night)
