In the EAV structure, you have to make a join for each attribute for each store. (if there is only one store then just for each attribute)
SELECT
e.entity_id as 'ID'
, e.sku
, pt.value AS 'Product Title'
, bl.value AS 'Brix Level'
FROM catalog_product_entity as e
left join catalog_product_entity_text as pt on pt.entity_id = e.entity_id and pt.attribute_id = {xx}
left join catalog_product_entity_text as bl on bl.entity_id = e.entity_id and bl.attribute_id = {yy}
group by e.entity_id
where {xx} and {yy} is the attribute_id for Product Title and Brix Level respectively.
(if you don't know the attribute_id, you can use a subquery attribute_id in (select attribute_id from eav_attribute where attribute_code = 'brix_level' and entity_type_id = 4)
I assumed product title
is text, if not, change table name accordingly, e.g. catalog_product_entity_varchar
.
SKU is a static type, so it is stored in the entity table as a column
