Searching for local Semolina & Durum

I've had excellent experiences with Heartland Mill, both in customer service and in their products, including durum.  Their online ordering is not operational at the moment, but a quick phone call will get you the info you need.  Most if not all of their products are organic.  You can get both berries and ground flour.  I was not able to tell if they are using the stone mill for the durum/semolina--they use the stone grinding for their whole wheat products and modified roller-milled for the white.  Their prices are very competitive even with shipping included given the quality of the flours and berries.  Hope you find something that will work for you!

Welcome to The Fresh Loaf!

General Mills has 50 pound bags of two types of gritty semolina (enriched and not-enriched), and two types of roller-milled fine durum flour (enriched and not-enriched).  There is sure to be a GM distributor near you. Annapolis, right?  See the product listings here, and for each product, follow link to distributor lookup:

https://www.generalmillscf.com/products/category/flour

Select "durum and semolina" in the product filters.

Pull up the PDF spec sheets (spec sheets are on each individual product page) to see ash%. Both types of the fine durum flour have .99% ash. Both types of the gritty semolina have .79% ash.

If you're willing  to use Canadian durum, it is available in 20 pound bags at most Indian grocery stores. One brand/type is stone-ground.  See my write up of various brands/types at:

I've used:

• Sher brand roller-milled whole grain durum aka "Fiber Wala". 
• Sher brand roller-milled refined (low bran) durum aka "Desi Style". 
• Golden Temple roller-milled white/red bag - reconstituted with some bran but it's not whole grain. 
• Patel brand stone-ground whole grain durum. 

I've seen:

• Golden Temple yellow/green bag with less bran and more finely ground than the white/red bag.

There are plenty of Indian grocery stores in and near Annapolis. See:

The Patel brand stone-ground sounds the closest to what you're looking for -- stone ground, nothing added.  But it is 100% whole wheat. So it is difficult to work with at anything over about 30% of total flour. It's the durum _bran_ that makes it difficult, absorbing extra water, and turning to rubbery glue.  It's fine at 100% for pasta, tortillas, and chapatis. But for yeasted _loaves_, i've been limiting its use to 25%.

Hope this help. Good luck.
