Do you buy whole or milled malt?

The basis malt I buy milled. But I plan not to buy more basis malt home than I can use in 3 months time coz to risk of less efficacy, lipids turning old, giving metallic tastes etc.. By basis malt I mean Maris Otter, Pilsner Malt and Wheat Malt. For the more special malts I buy them home in 1 kg un-milled and then mill them by cake roller (nice job for the kids) or by using the Cafe grinder!wp_20161104_002
